Evaluation of the Efficiency and Complications of the Consequtive Proning in Covid -19 ICU

Thirty -one confirmed Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2 ) infected patients with Acute Respiratory Distress Syndrome (ARDS) and placed in prone position(PP) for 3 times (PP1, PP2, PP3)consecutively will be included. Arterial blood gases (ABG), partial pressure of arterial oxygen/ fraction of inspired oxygen (PaO2/FiO2 ) ratios, partial pressure of carbondioxide (PaCO2), positive end expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) values will be recorded before (bPP), during (dPP)and after (aPP) every prone positioning. Eye, skin, nerve and tube complications related to prone positions wll be recorded
