In this study, the COVID-19 patients hospitalized in the intensive care unit due to respiratory failure will be evaluated. Participants will be divided into two groups as patients undergoing lung ultrasonography (Group Ultrasonography ) and those without lung ultrasonography (Group Control).~While performing lung ultrasonography, each hemithorax will be evaluated using anterior axillary line and posterior axillary line into anterior, lateral and posterior region, and each region will be divided into 6 quadrants, upper and lower. Each hemithorax will be scanned by the investigators, scored in 6 regions using a convex ultrasonography probe with the Lung Ultrasound Score (LUS score).~Participants in both groups will be evaluated by comparing arterial blood gas analyzes before examination (with/without ultrasonography), at the 2nd and 12th hours. Is there any change in arterial blood gas values such as PO2 and PCO2 at 0, 2 and 12 hours so that oxygenation and ventilation between Group Ultrasonograpy and Group Control will be evaluated?
In COVID-19 patients hospitalized in the intensive care unit due to respiratory failure, lung ultrasonography will be tried to be given an appropriate position that will effectively use lung capacity and its effect on oxygenation will be investigated.
