[Physiotherapy during and after acute exacerbation of COPD]. / La kinésithérapie en per- et post-exacerbation immédiate de BPCO.

INTRODUCTION: Exacerbations are major events in the course and prognosis of COPD. Following acute exacerbation of COPD (AECOPD), functional recovery is not always complete and the risk of relapse is high, requiring proactive management. STATE OF THE ART: Pulmonary and extrapulmonary consequences of AECOPD require comprehensive and individualized care. Muscle function and nutritional status are key elements to target. Pulmonary rehabilitation is an effective strategy designed to deal with these aspects and to facilitate a comprehensive, patient-centered approach. PERSPECTIVES: Access to pulmonary rehabilitation programs is limited, and existing barriers need to be more precisely identified as a first step toward their possible removal. Long-term exercise maintenance strategies likewise warrant further study. CONCLUSION: The physiotherapist has a major role to assume in per- and post-exacerbation management of people with COPD; it is up to him to assess the patient and to put into place an individualized pulmonary rehabilitation program; it is also up to him to provide long-term support, helping the patient to maintain an active lifestyle while coping with a chronic pathology.

[Physiotherapy and COVID-19. From intensive care unit to home care-An overview of international guidelines]. / Kinésithérapie et COVID-19 : de la réanimation à la réhabilitation à domicile. Synthèse des recommandations internationales.

INTRODUCTION: The new coronavirus disease 2019 (COVID-19) is responsible for a global pandemic and many deaths. This context requires an adaptation of health systems as well as the role of each healthcare professional, including physiotherapists. STATE OF THE ART: In order to optimize the management of people with COVID-19, many savant societies published guidelines about physiotherapy interventions within the crisis but none offered a global overview from the intensive care unit to home care. Therefore, the aim of this review is to offer an overview of recommended physiotherapy interventions in order to facilitate the management of these patients, whatever the stage of the disease. PERSPECTIVES: Owing to the emergent character of the COVID-19, actual guidelines will have to be adjusted according to the evolution of the pandemic and the resources of the hospital and liberal sectors, in particular for the long-term follow-up of these patients. Current and future research will aim to assess the effectiveness of physiotherapy interventions for people with COVID-19. CONCLUSION: The emergence of COVID-19 required a very rapid adaptation of the health system. The role of physiotherapists is justified at every stage of patients care in order to limit the functional consequences of the disease.

[Noninvasive ventilation during pulmonary rehabilitation in COPD patients]. / Ventilation non invasive au cours de la réhabilitation respiratoire des patients atteints de BPCO.

INTRODUCTION: Pulmonary rehabilitation is currently the gold standard treatment for patients with chronic obstructive pulmonary disease (COPD). However, the workload achieved may be insufficient to obtain physiological benefits because of the restricted respiratory capacity. BACKGROUND: In patients with COPD, changes in flow as well as biomechanical factors (distension) compromise respiratory adaptation to exertion. Some studies have shown that noninvasive ventilation (NIV) during exercise has a positive effect on respiratory muscle workload, physiological parameters and perceived exertion. However the evidence remains insufficient regarding the effects of the NIV during comprehensive pulmonary rehabilitation programs. OBJECTIVES: The identification of criteria which determine responsive patients is necessary in order to reduce human and time costs and to optimize the use of NIV during exercise. CONCLUSIONS: NIV is used during training to overcome dyspnoea and to increase muscle workload. Further studies are needed to verify the effectiveness of NIV in pulmonary rehabilitation.

Non-invasive ventilation: evaluation of CO2 washout by intentional leaking in three recent oronasal masks. A pilot study.

BACKGROUND: Many types of interfaces with intentional leaks exist for Non Invasive Ventilation. The purpose of intentional leaks is to remove CO2 from the interface, however the calibration does not allow a sufficiently large flow and rebreathing of CO2 can occur. The aim of this study was to compare the CO2 rinsing capacities of three new generation oronasal masks with intentional leaks (A: Quattro®, [Resmed]; B: Amara® [Respironics]; C: Forma® [Fisher&Paykel]) in healthy subjects. METHODS: Seventeen healthy volunteers were included in this prospective cross-sectional, randomized, double-blinded trial. Each subject underwent ventilation with a home ventilator (IPAP: 14 cmH2O; EPAP: 4 cmH2O) with each mask consecutively. Transcutaneous capnography (PtcCO2) recordings were carried out throughout the trial and ventilator data (tidal volume, respiratory rate, minute ventilation and unintentional leaks) were also analyzed. Mask comfort was assessed using a visual analog scale (0 to 10). RESULTS: The results showed no differences in PtcCO2 between masks (P=0.82). There were no significant differences in respiratory parameters (tidal volume, P=0.79; respiratory rate, P=0.65; minute ventilation, P=0.12) between masks. The rate of unintentional leaks were significantly lower for Mask A (P=0.016). Subjects rated Mask A and Mask C as more comfortable than Mask B (P=0.041). CONCLUSION: There was no effect of mask on PtcCO2 in healthy subjects. The mask with the highest comfort rating had not the lowest rate of unintentional leaks.
