Prone Positioning in COVID-19 Patients
The Effect of Prone Positioning on Oxygenation and Respiratory Mechanics in Patients With COVID-19 Pneumonia
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.

Annen: Prone Positioning
Patients will be ventilated in volume-controlled mode with Vt at 6 ml/kg of predicted body weight.
Prone positioning will be performed over periods of 16 hours when PaO2/FiO2 was persistently lower than 150 mm Hg.
Flow, volume, and airway pressure will bw measured by ventilators.
Measurements of oxygenation and respiratory mechanics were performed at 5 and 15 cmH20 PEEP levels and will be repeated every season as before first period of prone positioning, before supine positioning, and again before second period of prone positioning.
Total PEEP and plateau pressure will be measured by a short end-expiratory and an end-inspiratory occlusion respectively.
Complete airway closure will be assessed by performing a low-flow (4 L/min) inflation( PV tool) (9).
The potential for lung recruitment will be assessed by means of the R/I ratio (10).

Oxygenation will be calculated as PaO2/ FiO2 ratio.Static compliance will be calculated as tidal volume divided driving pressure.The potential for lung recruitment will be assessed by means of the R/I ratio (10).
