Effect of Prone Position on Oxygen, Blood Gas, and Respiratory Parameters in Intensive Care Patients With COVID-19-induced ARDS

Patients assigned to the Prone Position Group were placed in the prone position (lying face down) for 30 minutes once daily over two consecutive days while hospitalized in the ICU for COVID-19-induced ARDS. The intervention was performed between 12:30 and 13:00 under nurse supervision. Oxygen saturation, blood gas parameters (SaO₂, PO₂, PCO₂, pH, lactate, sodium), and respiratory rate were measured before and after each prone positioning session. The procedure was standardized across patients and no additional treatments were introduced during the intervention period.
