Feasibility and physiological effects of prone positioning in non-intubated patients with acute respiratory failure due to COVID-19 (PRON-COVID): a prospective cohort study

Coppo, Anna et al. The Lancet Respiratory Medicine. 2020; Volume 8, Issue 8, 765-774

This prospective cohort study aimed to assess the feasibility and effect on gas exchange of prone positioning in 56 awake, non-intubated patients with COVID-19-related pneumonia. Several variables were evaluated including demographics, anthropometrics, arterial blood gas, and ventilation parameters. The primary measured outcome was the variation in oxygenation between baseline and resupination, which served as an index of pulmonary recruitment. Findings have shown that prone positioning in awake, spontaneously breathing patients is achievable outside of the critical care environment in the majority of the patients. Improvements have been observed in oxygenation via Helmet CPAP interface (n=44), reservoir mask (n=9) and Venturi mask (n=3), during prone position, which was preserved upon resupination by half of the patients for 1 hour or more, as well as non-significant reduction in dyspnoea. Furthermore, patient discomfort was minimal and prone position was found to be a valuable patient engaging technique that improved blood gas parameters in the short term in patients with COVID-19-related pneumonia.
