Brief summary: Prone positioning improves oxygenation in patients with ARDS (1-3). Patients with severe ARDS due to COVID-19 are candidates for prone position. It should be started within 36-48 h and maintained 1, 3). Prone ventilationARDS based on a randomized trial that showed a mortality benefit (PROSEVA) (3).

The improvement of oxygenation occurs by making ventilation more homogeneous, limiting ventilator-associated lung injury (4-6).

Prone positioning was as effective in improving oxygenation, static respiratory system compliance (Crs) (7).

Higher PEEP should be applied when there is a high recruitability potential of the lung. This study aimed to investigate whether prone positioning changes the recruitability position of the lung.in COVID-ARDS.
