In this study, with inspiration/expiration 1:2 and 1:1 time ratios in pressure controlled ventilation mode with different slope times mechanical power will be calculated in covid ARDS patients. In this way, the effect of every 5% slope time change in PCV on mechanical power and SPO2 will be investigated.
The investigators are planning to investigate the effect of each 5% slope time change on mechanical power and SPO2 of the patients with Covid 19 ARDS diagnosis which are on mechanical ventilation PCV mode support.
