ABSTRACT

Abstract Introduction: Dentofacial deformity (DFD) and the breathing mode can change the head posture. However, head posture changes after orthognathic surgery are controversial, and no studies were found on the relationship between the head posture and breathing mode in adults with DFD. Objective: To identify the main head posture changes in young adults affected by DFD, to verify if orthognathic surgery modifies the breathing mode and head posture, and if the breathing mode is associated with the head posture. Methods: Twenty-five young adults were assessed and divided in dentofacial deformity group (DFD; n = 15; x̅ = 28 years) and control group with dentofacial harmony (CG; n = 10; balanced by gender and age with the study group). Breathing mode was evaluated according to the orofacial myofunctional evaluation protocol, and biophotogrammetry was used in the head posture analyses. For the DFD group, the evaluations were performed pre and post the orthognathic surgery (pre- and post-DFD). Results: For the DFD group, the breathing mode modified after orthognathic surgery (p = 0.003), but with difference from GC (p = 0.027). No changes were found in head posture after orthognathic surgery, but significant difference was seen between post-DFD and GC for head inclination (p = 0.017). No relationship was observed between breathing mode and head posture (p > 0.05). Conclusion: After orthognathic surgery, a spontaneous improvement of breathing was seen in the sample. It was not possible to verify changes in head posture and association with breathing mode and head posture.


Resumo Introdução: A deformidade dentofacial (DDF) e o modo respiratório podem alterar a postura de cabeça. Entretanto as modificações da postura de cabeça após a cirurgia ortognática são controversas e não foram encontrados estudos que apontassem relação entre a postura de cabeça e o modo respiratório em adultos com DDF. Objetivo: Identificar as principais alterações na postura de cabeça em adultos jovens com DDF, verificar se a cirurgia ortognática altera o modo respiratório e a postura de cabeça e se o modo respiratório está associado com a postura de cabeça. Métodos: Foram avaliados 25 jovens adultos, os quais foram divididos no grupo deformidade dentofacial (DDF; n = 15; x̅ = 28 anos) e grupo controle com harmonia dentofacial (GC; n = 10; equilibrados por gênero e idade com o grupo de estudo). O modo respiratório foi analisado de acordo com o protocolo de avaliação miofuncional orofacial e a postura de cabeça foi avaliada por meio da biofotogrametria. Para o grupo DDF, as avaliações foram realizadas antes e após a cirurgia ortognática (pré e pós-DDF). Resultados: Para o grupo DDF, o modo respiratório se modificou após a cirurgia ortognática (p = 0,003), porém com diferença em relação ao GC (p = 0,027). Não houve modificação na postura de cabeça após a cirurgia ortognática, porém observou-se diferença significativa entre os grupos pós-DDF e GC para a inclinação de cabeça (p = 0,017). Não observou-se relação entre o modo respiratório e a postura de cabeça (p > 0,05). Conclusão: Após a cirurgia ortognática, notou-se melhora espontânea da respiração na amostra estudada. Não foi possível verificar modificações na postura de cabeça e associação entre modo respiratório e postura de cabeça.

ABSTRACT

The nasal strip is widely used in horses during exercise, but effects of using a nasal strip are controversial and little is known about its effect on horses undergoing endurance events. The aim of this study was to determine whether the use of nasal strips influences alveolar cell population assessed by bronchoalveolar lavage (BAL), tidal volume, and nasal airflow rate. Six Arabian horses were subjected to two low intensity tests on a treadmill, with and without application of a commercial external nasal strip. Tidal volumes and airflow rates were measured during the test; two hours after the test, BAL was performed to assess cytology of pulmonary secretions. The lavage fluid showed increased neutrophil count after exercise in animals with the nasal strip (P<0.05). This suggests that turbulence of airflow through the nasal cavity may have diminished with nasal strip use, thus allowing larger particles to be deposited more distally in the respiratory system, inducing a more intense neutrophilic response. No differences in tidal volumes or airflow rates were observed between groups (with or without nasal strips) during the test (P>0.05). The use of nasal strips seems to influence alveolar cell population during and after exercise in horses after low intensity exercise tests. Further studies are needed to verify whether alveolar cell population is related to poor exercise performance in horses.(AU)


A fita nasal é amplamente utilizada em equinos durante o exercício, porém seus resultados são controversos e pouco conhecidos em animais que disputam provas de resistência. O objetivo deste trabalho foi verificar se o uso da fita nasal influencia a população de células alveolares por meio de lavado broncoalveolar, volume corrente e fluxo de ar nasal. Foram utilizados seis equinos da raça Árabe, que realizaram dois testes de longa duração em esteira, sendo um teste com a fita e outro sem a fita nasal. Fluxo e volume respiratório foram mensurados durante o teste; duas horas após o término do exercício, foi realizado lavado broncoalveolar para realização de citologia da secreção pulmonar. Foi verificada maior porcentagem de neutrófilos após o exercício nos animais que se exercitaram com a fita nasal (P<0,05), indicando que o turbilhonamento na passagem do ar através da cavidade nasal pode ter diminuído, permitindo que partículas maiores se depositassem em porções mais distais do sistema respiratório, induzindo uma resposta neutrofílica mais intensa. Não houve diferenças entre os parâmetros ventilatórios analisados entre os animais quando correram com ou sem a fita nasal (P>0,05). O uso da fita nasal parece influenciar alguns parâmetros, durante e após o exercício, em animais que realizam provas de longa duração. Outros estudos devem ser realizados para verificar se essa influência pode melhorar o desempenho desses animais em exercícios predominantemente aeróbicos.(AU)

ABSTRACT

RESUMO A respiração espontânea pode ser prejudicial para pacientes com pulmões previamente lesados, especialmente na vigência de síndrome do desconforto respiratório agudo. Mais ainda, a incapacidade de assumir a respiração totalmente espontânea durante a ventilação mecânica e a necessidade de voltar à ventilação mecânica controlada se associam com mortalidade mais alta. Existe uma lacuna no conhecimento em relação aos parâmetros que poderiam ser úteis para predizer o risco de lesão pulmonar autoinflingida pelo paciente e detecção da incapacidade de assumir a respiração espontânea. Relata-se o caso de um paciente com lesão pulmonar autoinflingida e as correspondentes variáveis, básicas e avançadas, de monitoramento da mecânica do sistema respiratório, além dos resultados fisiológicos e clínicos relacionados à respiração espontânea durante ventilação mecânica. O paciente era um homem caucasiano com 33 anos de idade e história clínica de AIDS, que apresentou síndrome do desconforto respiratório agudo e necessitou ser submetido à ventilação mecânica invasiva após falha do suporte ventilatório não invasivo. Durante os períodos de ventilação controlada, adotou-se estratégia de ventilação protetora, e o paciente mostrou evidente melhora, tanto do ponto de vista clínico quanto radiográfico. Contudo, durante cada período de respiração espontânea sob ventilação com pressão de suporte, apesar dos parâmetros iniciais adequados, das regulagens rigorosamente estabelecidas e do estrito monitoramento, o paciente desenvolveu hipoxemia progressiva e piora da mecânica do sistema respiratório, com deterioração radiográfica claramente correlacionada (lesão pulmonar autoinflingida pelo paciente). Após falha de três tentativas de respiração espontânea, o paciente faleceu por hipoxemia refratária no 29° dia. Neste caso, as variáveis básicas e avançadas convencionais não foram suficientes para identificar a aptidão para respirar espontaneamente ou predizer o risco de desenvolver lesão pulmonar autoinflingida pelo paciente durante a ventilação de suporte parcial.


ABSTRACT Spontaneous breathing can be deleterious in patients with previously injured lungs, especially in acute respiratory distress syndrome. Moreover, the failure to assume spontaneous breathing during mechanical ventilation and the need to switch back to controlled mechanical ventilation are associated with higher mortality. There is a gap of knowledge regarding which parameters might be useful to predict the risk of patient self-inflicted lung injury and to detect the inability to assume spontaneous breathing. We report a case of patient self-inflicted lung injury, the corresponding basic and advanced monitoring of the respiratory system mechanics and physiological and clinical results related to spontaneous breathing. The patient was a 33-year-old Caucasian man with a medical history of AIDS who developed acute respiratory distress syndrome and needed invasive mechanical ventilation after noninvasive ventilatory support failure. During the controlled ventilation periods, a protective ventilation strategy was adopted, and the patient showed clear clinical and radiographic improvement. However, during each spontaneous breathing period under pressure support ventilation, despite adequate initial parameters and a strictly adjusted ventilatory setting and monitoring, the patient developed progressive hypoxemia and worsening of respiratory system mechanics with a clearly correlated radiographic deterioration (patient self-inflicted lung injury). After failing three spontaneous breathing assumption trials, he died on day 29 due to refractory hypoxemia. Conventional basic and advanced monitoring variables in this case were not sufficient to identify the aptitude to breathe spontaneously or to predict the risk and development of patient self-inflicted lung injury during partial support ventilation.

ABSTRACT

Objective: To compare in neonates with transitory tachypnea if chest rebalancing thoraco-abdominal method (RTA) increased immediate pain. Methods: This was a randomized controlled clinical trial. Forty-nine neonates with transitory tachypnea and aged < 72 hours were included to receive either conventional physiotherapy (CP) or RTA method. Participants received usual care and one 15- minute session of chest physiotherapy. Neonatal Infant Pain Scale (NIPS), peripheral oxygen saturation, heart rate, respiratory rate, axillary temperature before and after chest physiotherapy were recorded. Kruskal-Wallis ANOVA and Mc Nemar test were used to compare differences between measures. The relative risk (RR) for pain after interventions was calculated using a Poisson regression model (robust estimation). A significance level of 5% (p < 0.05) was adopted for all analyses. Results: RTA was not associated to pain. After chest physiotherapy, NIPS reduced (2 versus 3, p < 0.001) and number of neonates with pain reduced (10.2% versus 28.6%, p = 0.02). RR for pain after chest physiotherapy in comparison to before was 0.3 (95% CI 0.15-0.41; p = 0.02); respiratory frequency decreased after chest physiotherapy (58 versus 70, p < 0.001) and peripheral oxygen saturation increased (98% versus 96%, p < 0.001). Conclusion: In neonates with transitory tachypnea, in the first 72 hours of life, RTA did not influence pain evaluation, chest physiotherapy was safe and reduced immediate pain. (AU)


Objetivo: Comparar em recém-nascidos com taquipneia transitória se o método reequilíbrio tóraco-abdominal (RTA) aumentou a dor imediatamente após. Métodos: Estudo de ensaio clínico randomizado. Quarenta e nove recémnascidos com diagnóstico de taquipneia transitória com menos de 72 horas de vida, foram incluídos para receber fisioterapia respiratória. Os participantes receberam os cuidados usuais e uma sessão de fisioterapia convencional ou do método reequilíbrio tóraco-abdominal. Foram registradas a escala NIPS (Neonatal Infant Pain Scale), a saturação periférica de oxigênio, a frequência cardíaca, a frequência respiratória e a temperatura axilar antes e depois da fisioterapia. Para as comparações entre as medidas, foram utilizados o teste de ANOVA de Kruskal-Wallis e o teste de McNemar. O risco relativo de dor após os procedimentos foi calculado usando o modelo de regressão de Poisson (estimação robusta). Foi considerado o nível de significância de 5% para todas as análises (p < 0,05). Resultados: O método RTA não foi associado a dor. Após a fisioterapia respiratória, a escala NIPS reduziu (2 versus 3, p < 0,001) e a proporção de recém-nascidos com dor também reduziu (10,2% versus 28,6%, p = 0,02). O risco relativo de dor após a fisioterapia respiratória em comparação a antes, foi de 0,3 (IC 95% 0,15-0,41; p = 0,02), a frequência respiratória diminuiu (58 versus 70, p < 0,001) e a saturação periférica de oxigênio aumentou (98% versus 96%, p < 0,001). Conclusão: Em recém-nascidos com taquipneia transitória nas primeiras 72 horas de vida, o método RTA não influenciou a avaliação da dor, a fisioterapia respiratória foi segura e reduziu a dor imediatamente após.

ABSTRACT

La principal función del sistema respira-torio es el intercambio de gases durante la inspiración y expiración, una alteración en cualquier parte de este sistema puede generar problemas respiratorios agudos como en el caso de la insuficiencia respiratoria aguda (IRA), que es la incapacidad pulmonar de cumplir con el intercambio gaseoso de oxígeno y dióxido de carbono entre el aire ambiental y la sangre circu-lante1, está acompañada de varios signos y síntomas como taquipnea, cianosis entre otros2, es de inicio súbito, y cons-tituye la causa de ingreso a las unidades de emergencia, por ello la Organización Mundial de la Salud (OMS) indica que "cientos de millones de personas sufren cada día las consecuencias de enferme-dades respiratorias"3. En los indicadores Básicos-Ecuador 2012 del Ministerio de Salud Pública (MSP) del Ecuador a nivel general registró 4 122 muertes por IRA, correspondió a la Provincia de Pichincha 8254, en el Hospital de Especialidades Carlos Andrade Marín (HECAM), la primera causa de ingreso correspondió a neumonía con el 41,29% en el periodo de enero-septiembre 2018 (Coordinación General de Planificación y Estadísticas HECAM).La ruta planteada constituye una herra-mienta que permite al personal de enfer-mería realizar una evaluación efectiva a través de una valoración inicial, primaria y secundaria, con el propósito de evitar complicaciones durante el cuidado de pa-cientes pediátricos con insuficiencia res-piratoria aguda en la Unidad Pediátricos Área de Emergencia (UPAE).


1. INTRODUCTION The main function of the respiratory system is the exchange of gases during inharing and exhaling processes. An al-teration in any part of this system can generate acute respiratory problems as in the case of acute respiratory failure (ARF), which is the inability of the lung to comply with the gaseous exchange of oxygen and carbon dioxide between the external air and circulating blood1. It is accompanied by various signs and symp-toms such as tachypnea, cyanosis, among others2, is of sudden start, and is the cause of admission to emergency units. This is why the World Health Organization (WHO) indicates that "hundreds of millions of people suffer the consequences of respiratory diseases every day"3. In the Basic Indicators-Ecuador 2012 of the Mi-nistry of Public Health of Ecuador at the general level recorded 4 122 deaths due to ARI, corresponding to the Province of Pichincha 8254, in the Carlos Andrade Marín Specialties Hospital (HECAM). The first cause of admission corresponded to pneumonia with 41,29% in the period January-September 2018 (General Coordination of Planning and Statistics HECAM).The proposed route constitutes a tool that allows the nursing staff to perform an effective evaluation through an initial, primary, and secondary assessment, with the purpose of avoiding complications during the care of pediatric patients with acute respiratory failure in the Pediatric Emergency Area Unit (UPAE).

ABSTRACT

Abstract Introduction Foreign body aspiration (FBA) is a potentially fatal paediatric emergency. Our objective was to highlight the importance of a multidisciplinary approach to difficult/doubtful diagnosis. Case report 34-month-old girl referred for urgent rigid bronchoscopy after suspected metallic blade ingestion (found chewing on it). She had a previous recurrent history of wheezing. The physical examination revealed face/lip wounds, traces of powder on her teeth but no breathing difficulty. The plain X-Ray revealed radiopaque images of the upper pulmonary field and gastric chamber. In the absence of FBA clinical signs but considering a previous history of bronchial hyperresponsiveness, a direct digital radiographic study was performed. There were no images compatible with foreign bodies: the results were interpreted as artefacts and no bronchoscopy was performed. Conclusions A careful pre-anaesthetic evaluation, a high level of suspicion and excellent multidisciplinary communication led to the recognition of false radiologic findings. A conservative approach was followed and invasive procedures in a remote location, with high anaesthetic risk for the paediatric population were avoided.


Resumen Introducción La aspiración de cuerpo extraño (ACE) es una emergencia pediátrica potencialmente fatal. La intención del presente artículo es resaltar la importancia de un abordaje multidisciplinario en caso de un diagnóstico difícil/dudoso. Reporte de caso Se trata de una paciente de 4 meses de edad remitida para broncoscopia rígida de urgencia, luego de la sospecha de ingestión de una hojilla metálica (se encontró a la bebé mordiéndola). La paciente tenía antecedentes de sibilancia. Al examen físico se encontraron heridas en la cara y los labios, rastros de polvo en los dientes, pero no había dificultad respiratoria. El examen de rayos-x mostraba imágenes radio opacas en el cuadrante superior derecho del pulmón y en la cámara gástrica. En virtud de la ausencia de signos clínicos de ACE en una paciente con antecedentes de hiperresponsividad bronquial, se realizó un estudio radiográfico digital. No hubo imágenes compatibles con cuerpos extraños: los resultados se interpretaron como artefactos y no se realizó la broncoscopia. Conclusiones Un cuidadoso examen pre-anestesia, el alto grado de sospecha y una excelente comunicación multidisciplinaria, permitieron el reconocimiento de hallazgos radiológicos falsos. Se siguió un abordaje conservador, evitando así procedimientos invasivos en lugares remotos con alto grado de riesgo para la población pediátrica.

ABSTRACT

RESUMEN La lesión pulmonar aguda producida por transfusión (TRALI, por sus siglas en inglés) es un síndrome clínico relativamente raro, que puede constituir una amenaza para la vida y que se caracteriza por insuficiencia respiratoria aguda, edema pulmonar no cardiogénico e hipotensión arterial durante o en el transcurso de 6 horas después de una transfusión de productos hemáticos. Aunque su verdadera incidencia es desconocida, se le ha atribuido 1 caso por cada 5000 transfusiones de cualquier producto hemático y ha sido una de las causas más frecuentes de muerte relacionada con la transfusión. Se presenta un caso de TRALI en el perioperatorio de una cirugía cardíaca con manifestaciones clínicas extremas, cuyo abordaje terapéutico fue extremadamente difícil para el equipo médico-quirúrgico, debido al contexto clínico en el que se presentó: cirugía cardíaca con circulación extracorpórea por diagnóstico de endocarditis infecciosa, lesión pulmonar previa y antecedente de otro tipo de reacción postransfusional.


ABSTRACT Transfusion-Related Acute Lung Injury (TRALI) is a relatively unusual, life-threatening clinical syndrome, characterized by acute respiratory failure, hypotension, and non-cardiogenic pulmonary edema during or within 6 hours after a blood product transfusion. Although its true incidence is unknown, it has been attributed one case per 5.000 transfusions of any blood product and has been one of the most frequent causes of transfusion-related death. We present a case of TRALI in the perioperative period of cardiac surgery with extreme clinical manifestations, whose therapeutic approach was extremely difficult for the medical-surgical team, due to its complex clinical setting: cardiac surgery with cardiopulmonary bypass due to diagnosis of infective endocarditis, previous lung injury and history of other post-transfusion reaction.

ABSTRACT

One of critical technologies in a non-invasive positive airway pressure respirator is to output the airflow for meeting the requirement of respiratory patient in breath. In order to develop a safe and reliable blower driving system, a circuit based on the special chips MC33035 and MC33039 was designed. The linear relationship between the input control voltage and the output air flow was achieved. This designed circuit will be embedded in the non-invasive ventilator system as a module. And based on this circuit, the secure and controllable ventilation flow can be performed.

ABSTRACT

ABSTRACT Objective: High prevalences of muscle weakness and impaired physical performance in hospitalized patients recovering from COVID-19-associated pneumonia have been reported. Our objective was to determine whether the level of exercise capacity after discharge would affect long-term functional outcomes in these patients. Methods: From three to five weeks after discharge from acute care hospitals (T0), patients underwent a six-minute walk test (6MWT) and were divided into two groups according to the distance walked in percentage of predicted values: <75% group and ≥75% group. At T0 and three months later (T1), patients completed the Short Physical Performance Battery and the Euro Quality of Life Visual Analogue Scale, and pulmonary function and respiratory muscle function were assessed. In addition, a repeat 6MWT was also performed at T1. Results: At T0, 6MWD values and Short Physical Performance Battery scores were lower in the <75% group than in the ≥75% group. No differences were found in the Euro Quality of Life Visual Analogue Scale scores, pulmonary function variables, respiratory muscle function variables, length of hospital stay, or previous treatment. At T1, both groups improved their exercise capacity, but only the subjects in the <75% group showed significant improvements in dyspnea and lower extremity function. Exercise capacity and functional status values returned to predicted values in all of the patients in both groups. Conclusions: Four weeks after discharge, COVID-19 survivors with exercise limitation showed no significant differences in physiological or clinical characteristics or in perceived health status when compared with patients without exercise limitation. Three months later, those patients recovered their exercise capacity.


RESUMO Objetivo: Há relatos de altas prevalências de fraqueza muscular e de comprometimento do desempenho físico em pacientes hospitalizados em recuperação de pneumonia associada à COVID-19. Nosso objetivo foi determinar se o nível de capacidade de exercício após a alta altera os desfechos funcionais em longo prazo nesses pacientes. Métodos: Três a cinco semanas após a alta dos cuidados agudos (T0), os pacientes foram submetidos ao teste de caminhada de seis minutos (TC6) e divididos em dois grupos de acordo com a distância percorrida no TC6 (DTC6) em percentual do previsto: grupo <75% e grupo ≥75%. Em T0 e três meses depois (T1), os pacientes responderam à Short Physical Performance Battery e à Euro Quality of Life Visual Analogue Scale, e foram avaliadas a função pulmonar e a função muscular respiratória. Além disso, o TC6 foi repetido em T1. Resultados: Em T0, a DTC6 e as pontuações na Short Physical Performance Battery foram menores no grupo <75% do que no grupo ≥75%. Não foram encontradas diferenças nas pontuações na Euro Quality of Life Visual Analogue Scale, nas variáveis de função pulmonar e função muscular respiratória, no tempo de internação hospitalar ou no tratamento anterior. Em T1, ambos os grupos melhoraram a capacidade de exercício, mas apenas os indivíduos do grupo <75% apresentaram melhoras significativas na dispneia e na função dos membros inferiores. Os valores de capacidade de exercício e estado funcional retornaram aos valores previstos em todos os pacientes de ambos os grupos. Conclusões: Quatro semanas após a alta, os sobreviventes da COVID-19 com limitação ao exercício não apresentaram diferenças significativas nas características fisiológicas e clínicas ou na percepção do estado de saúde em comparação aos pacientes sem limitação ao exercício. Três meses depois, esses pacientes recuperaram sua capacidade de exercício.

ABSTRACT

Continuous positive airway pressure (CPAP) has been used to improve gas exchange and diaphragmatic function, among others benefits. Moreover, it can be used to increase exercise tolerance and positively influence ventilatory function and breathing pattern (BP) during exercise. However, there is no information about the long-term effects of CPAP, as an adjunct to an inpatient cardiac rehabilitation (CR) program, on BP and heart rate variability (HRV) of patients after coronary artery bypass grafting surgery (CABG). Twenty patients were allocated to receive, after randomization, standard inpatient CR without CPAP (control group - CG) or CR with CPAP between 10 to 12 cmH2O (CPAP group - CPG) associated with the exercises. Participants were assessed preoperatively and on the discharge day, in the sitting rest position. Outcome measurements included BP variables, collected by respiratory inductive plethysmography, and HRV, collected by polar precision performance. The CPG presented lower values of percent rib cage inspiratory and expiratory contributions to tidal volume (%RCi and %RCe) at discharge time, compared to CG. No statistical differences between groups were observed for HRV variables and both groups presented lower values of these indices, compared to preoperative ones. In this context, the patients who received CPAP throughout the whole rehabilitation program were discharged with a better BP, which could indicate more synchronized breathing. CPAP did not influence cardiac autonomic modulation in the long term.

ABSTRACT

La respiración comprende una serie mecanismos complejos, que van desde el intercambio de gases con el exterior hasta la utilización de oxígeno (O2) por la célula y la eliminación de dióxido de carbono (CO2). Estos mecanismos requieren de la coordinación de diferentes órganos y sistemas, que se encuentran estrechamente relacionados con la succión y la deglución en el neonato, convirtiéndose en un determinante a la hora de alimentar o no a un neonato por vía oral, sobre todo si este es nacido pretérmino o presenta alguna dificultad respiratoria. El objetivo de esta revisión es determinar los criterios más importantes para el inicio de la succión nutritiva en los neonatos con dificultades respiratorias, para ello se realiza la búsqueda de evidencia científica al respecto en diferentes bases de datos como PubMed, Scopus y Cochrane desde el año 2000 en adelante, en donde se eligen 70 artículos, de los cuales después de realizar el análisis de los títulos y resúmenes, se escogen los documentos potencialmente elegibles para ser analizados con el instrumento de evaluación metodológica AMSTAR. Se trabaja con 16 de ellos, considerados los más apropiados para el desarrollo de la temática, además se realiza el análisis teórico. Se concluyó que, dentro de los criterios más importantes para iniciar la succión nutritiva en pacientes con dificultades respiratorias, se encuentran la medición de la saturación periférica de oxígeno (SpO2), una coordinación de la triada SRD adecuada, la inexistencia de signos de alarma como la tos, la regurgitación nasal y el tiraje intercostal y una succión nutritiva a través de la lactancia materna, gracias a sus múltiples beneficios, incluida la disminución del riesgo de desaturación


Respiration comprises a series of complex mechanisms, ranging from the exchange of gases with the outside world to the use of oxygen (O2) by the cell and the elimination of carbon dioxide (CO2). These mechanisms require nourishing the coordination of different organs and systems, which are closely related to sucking and swallowing in the newborn, becoming a determining factor in whether a newborn is given orally, especially if it is born preterm or has any respiratory distress. The objective of this review is to determine the most important criteria for the initiation of nutritive sucking in neonates with respiratory difficulties, for which a search for scientific evidence in this regard is carried out in different databases such as PubMed, Scopus and Cochrane since the year 2000 onwards, in which 70 articles are chosen, from which after analyzing the titles and abstracts, the potentially eligible documents are chosen to be analyzed with the AMSTAR methodological evaluation instrument. It works with 16 of them, used the most appropriate for the development of the theme, in addition, the theoretical analysis is carried out. It was concluded that, among the most important criteria to initiate nutritional suction in patients with respiratory difficulties, are the measurement of peripheral oxygen saturation (SpO2), adequate coordination of the SRD triad, the absence of alarm signs such as cough, nasal regurgitation and intercostal pulling and nutritious sucking through breastfeeding, thanks to its multiple benefits including the reduction of the risk of desaturation.

ABSTRACT

Traditional methods of non-contact human respiratory rate measurement usually require complex devices or algorithms. Aiming at this problem, a non-contact respiratory rate measurement method based on only the RGB video information was proposed in this paper. The method consisted of four steps. Firstly, spatial filtering was applied to each frame of the input video. Secondly, a gray compensation algorithm was used to compensate for the gray level change caused by the environmental light. Thirdly, the gray levels of each pixel over time were filtered separately by a low-pass filter. Finally, the region of interest was determined based on the filtering results, and the respiration rate of the human is measured. The physical measurement experiments were designed, and the measurement accuracy was compared with that of the biological radar. The error of the proposed method was between - 5.5% and 3% in different detection directions. The results show that the non-contact respiration rate measurement method can effectively measure the human respiration rate.

ABSTRACT

Breathing pattern parameters refer to the characteristic pattern parameters of respiratory movements, including the breathing amplitude and cycle, chest and abdomen contribution, coordination, etc. It is of great importance to analyze the breathing pattern parameters quantificationally when exploring the pathophysiological variations of breathing and providing instructions on pulmonary rehabilitation training. Our study provided detailed method to quantify breathing pattern parameters including respiratory rate, inspiratory time, expiratory time, inspiratory time proportion, tidal volume, chest respiratory contribution ratio, thoracoabdominal phase difference and peak inspiratory flow. We also brought in "respiratory signal quality index" to deal with the quality evaluation and quantification analysis of long-term thoracic-abdominal respiratory movement signal recorded, and proposed the way of analyzing the variance of breathing pattern parameters. On this basis, we collected chest and abdomen respiratory movement signals in 23 chronic obstructive pulmonary disease (COPD) patients and 22 normal pulmonary function subjects under spontaneous state in a 15 minute-interval using portable cardio-pulmonary monitoring system. We then quantified subjects' breathing pattern parameters and variability. The results showed great difference between the COPD patients and the controls in terms of respiratory rate, inspiratory time, expiratory time, thoracoabdominal phase difference and peak inspiratory flow. COPD patients also showed greater variance of breathing pattern parameters than the controls, and unsynchronized thoracic-abdominal movements were even observed among several patients. Therefore, the quantification and analyzing method of breathing pattern parameters based on the portable cardiopulmonary parameters monitoring system might assist the diagnosis and assessment of respiratory system diseases and hopefully provide new parameters and indexes for monitoring the physical status of patients with cardiopulmonary disease.

ABSTRACT

Bronchial asthma is a common chronic respiratory disease,and its diagnosis is mainly based on symptoms,signs,and pulmonary function test.Wheezing is a major symptom of asthma attack,which shows no obvious sign in the early stage while appears after the disease has progressed.Therefore,bronchial asthma is difficult to be detected in early stages,which often leads to worsening of the disease conditions.Pulmonary function test can effectively monitor upper and lower airway abnormalities and is currently the main means for monitoring asthma.However,its accuracy is highly dependent on patient's motivation and cooperation,which obviously limits the scope of application,especially for preschoolers and infants.Hence,there is an urgent need for a new technology with the function of long-term breath sound monitoring and automatic breathing detection to overcome the existing clinical deficiencies.Breath sound analysis emerges in the era of medical artificial intelligence,which can digitally process and convert the collected respiratory sounds by using a variety of different methods to form characteristic signal parameters and model the relationship between parameters and diseases.As we know,breath sounds are closely related to airway changes,and thus the detection and analysis of the sounds can provide reliable clinical information for the progress and control evaluation of asthma.This review mainly summaries the research progress of respiratory sound analysis in recent years,hoping to provide reference for further research.

ABSTRACT

BACKGROUND@#Conventional pressure support ventilation (PSP) is triggered and cycled off by pneumatic signals such as flow. Patient-ventilator asynchrony is common during pressure support ventilation, thereby contributing to an increased inspiratory effort. Using diaphragm electrical activity, neurally controlled pressure support (PSN) could hypothetically eliminate the asynchrony and reduce inspiratory effort. The purpose of this study was to compare the differences between PSN and PSP in terms of patient-ventilator synchrony, inspiratory effort, and breathing pattern.@*METHODS@#Eight post-operative patients without respiratory system comorbidity, eight patients with acute respiratory distress syndrome (ARDS) and obvious restrictive acute respiratory failure (ARF), and eight patients with chronic obstructive pulmonary disease (COPD) and mixed restrictive and obstructive ARF were enrolled. Patient-ventilator interactions were analyzed with macro asynchronies (ineffective, double, and auto triggering), micro asynchronies (inspiratory trigger delay, premature, and late cycling), and the total asynchrony index (AI). Inspiratory efforts for triggering and total inspiration were analyzed.@*RESULTS@#Total AI of PSN was consistently lower than that of PSP in COPD (3% vs. 93%, P = 0.012 for 100% support level; 8% vs. 104%, P = 0.012 for 150% support level), ARDS (8% vs. 29%, P = 0.012 for 100% support level; 16% vs. 41%, P = 0.017 for 150% support level), and post-operative patients (21% vs. 35%, P = 0.012 for 100% support level; 15% vs. 50%, P = 0.017 for 150% support level). Improved support levels from 100% to 150% statistically increased total AI during PSP but not during PSN in patients with COPD or ARDS. Patients' inspiratory efforts for triggering and total inspiration were significantly lower during PSN than during PSP in patients with COPD or ARDS under both support levels (P < 0.05). There was no difference in breathing patterns between PSN and PSP.@*CONCLUSIONS@#PSN improves patient-ventilator synchrony and generates a respiratory pattern similar to PSP independently of any level of support in patients with different respiratory system mechanical properties. PSN, which reduces the trigger and total patient's inspiratory effort in patients with COPD or ARDS, might be an alternative mode for PSP.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT01979627; https://clinicaltrials.gov/ct2/show/record/NCT01979627.

ABSTRACT

Azotobacter vinelandii is a gram-negative soil bacterium that produces two biopolymers of biotechnological interest, alginate and poly(3-hydroxybutyrate), and it has been widely studied because of its capability to fix nitrogen even in the presence of oxygen. This bacterium is characterized by its high respiration rates, which are almost 10-fold higher than those of Escherichia coli and are a disadvantage for fermentation processes. On the other hand, several works have demonstrated that adequate control of the oxygen supply in A. vinelandii cultivations determines the yields and physicochemical characteristics of alginate and poly(3-hydroxybutyrate). Here, we summarize a review of the characteristics of A. vinelandii related to its respiration systems, as well as some of the most important findings on the oxygen consumption rates as a function of the cultivation parameters and biopolymer production.

ABSTRACT

BACKGROUND: γ-Aminobutyric acid (GABA) bypasses the TCA cycle via GABA shunt, suggesting a relationship with respiration. However, little is known about its role in seed germination under salt conditions. RESULTS: In this study, exogenous GABA was shown to have almost no influence on mungbean seed germination, except 0.1 mM at 10 h, while it completely alleviated the inhibition of germination by salt treatment. Seed respiration was significantly inhibited by 0.1 and 0.5 mM GABA, but was evidently enhanced under salt treatment, whereas both were promoted by 1 mM GABA alone or with salt treatment. Mitochondrial respiration also showed a similar trend at 0.1 mM GABA. Moreover, proteomic analysis further showed that 43 annotated proteins were affected by exogenous GABA, even 0.1 mM under salt treatment, including complexes of the mitochondrial respiratory chain. CONCLUSIONS: Our study provides new evidence that GABA may act as a signal molecule in regulating respiration of mungbean seed germination in response to salt stress.
