Video calls during the COVID-19 pandemic: A bridge for patients, families, and respiratory therapists.

BACKGROUND: In response to COVID-19 pandemic outbreak, healthcare procedures and modalities have changed considerably. Video calls may supply valid support for health care professionals, contributing to maintaining the communication between hospitalized patients and their families. The present study aimed to observe the experience of a group of respiratory therapists who conducted video calls between patients and their families in a COVID-19 unit. METHOD: Semistructured interviews (20-30 minutes duration) with the respiratory therapists who conducted the video calls in a COVID-19 unit in the North of Italy were performed. Participants joined the study voluntarily and, after receiving the informed consent, the interviews were audio-recorded. To better understand healthcare professionals' experience, the Interpretive Description methodology was adopted. RESULTS: Seven respiratory therapists (three males, four females; mean age 45.1 ± 14.4) were recruited. Sixteen codes emerged from the analysis, constituting five primary themes: Contact, Impact, Challenges, Centering, and Future. CONCLUSIONS: The findings shed light on the usability of video calls during this emergency period and their potential for future implementation. Specifically, this type of call may bridge the distances in such periods of care and help professionals to emotionally support patients and caregivers.

C-reactive protein correlates with tissue oxygen availability in patients with stable COPD.

BACKGROUND: Arterial oxygen tension, oxygen delivery to tissue, and systemic inflammation are recognized as pivotal factors in the progression of chronic obstructive pulmonary disease (COPD). However, interconnections between systemic inflammation and tissue oxygen availability are scantly investigated. Tissue oxygen availability depends on arterial PaO2, oxygen concentration, hemoglobin oxygen affinity (P50), and hemoglobin oxygen binding capacity (ceHb). As the integrated changes of those indices are summarized by oxygen extraction tension (PaO2x), the objective of this study was to explore the association between C-reactive protein (CRP) blood levels and either PaO2x or each of its determinants, in stable COPD. MATERIALS AND METHODS: Blood CRP and oxygen status of arterial blood were measured at rest while breathing room air in 44 moderate to severe stable COPD patients. PaO2x was calculated along the shape of oxygen binding curve as the oxygen tension resulting from removal of 2.3 mmol of oxygen per liter of blood. Multiple linear regression analysis was performed with PaO2, ceHb, and P50 as independent variables, and CRP as the dependent variable, adjusting for age and sex. The analysis was repeated using PaO2x as a sole independent variable. RESULTS: Multiple linear regression analysis indicated that ceHb, PaO2, and P50, were significant and independent predictors of CRP (R2 = 0.52, p < 0.0001). PaO2x alone was an even stronger predictor of CRP (R2 = 0.62, p < 0.0001). CONCLUSIONS: These findings indicate that physiological determinants of tissue oxygen availability are independently associated with CRP blood levels. Thus, improvement of tissue oxygen availability is a central therapeutic option to modulate the severity of systemic inflammatory processes in patients with COPD.
