This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Prone position ventilation has been shown to decrease mortality and improve oxygenation in ARDS patients. With best of our knowledge, no study reported physiological effect of prone position in SARS- CoV-2 infected ARDS patients. In this prospective observational study, data of n=20 consecutive laboratory confirmed SARS- CoV-2 patients with severe ARDS as per Berlin definition was included. Data of 20 patients analyzed with a median (Interquartile range, IQR) age of 56 (45.5- 67) y and median (IQR) P/F ratio of 56 (54- 66) with a median (IQR) PEEP of 12 (12- 14) before initiation of prone position. Seventy-five percentage (95% CI 53.1- 88.8) patients were prone responders at 16h prone session and 50 (95% CI 29.9- 70.1) % patients were sustained responders. There was a significant decrease in plateau airway pressure (p<0.0001), peak airway pressure (p<0.0001) and driving pressure(p<0.0001) and increase in static compliance (p=0.001), P/F ratio (p<0.0001), PaO2 (p=0.0002)and SpO2 (p=0.0004) at 4h and 16h since initiation of prone session and also after return of supine position. Prone position in SARS- CoV-2 infected severe ARDS patients is associated with improvement in lung compliance and oxygenation in two- third of the patients and persisted in half of the patients.
