Flow-controlled Ventilation (FCV) in Moderate Acute Respiratory Distress Syndrome (ARDS) Due to COVID-19

Arterial blood gasses will be drawn during baseline PCV, and every 15 minutes during FCV and VCV respectively. pO2 (mmHg), pCO2 (mmHg) and pH will be recorded.

Hemodynamic parameters (invasive arterial blood pressure (mmHg) and heart rate (beats per minute)) will be recorded every 5 minutes.

Tidal volume (ml), respiratory rate (breaths per minute), minute volume (l/min), dynamic compliance (ml/cmH2O), resistance (cmH2O/l/min), plateau pressure (cmH2O), mean airway pressure (cmH2O), positive end-expiratory pressure (cmH2O), peak inspiratory pressure (cmH2O) and fraction of inspired oxygen will be recorded every 5 minutes.
