Impact of proning with and without inhaled pulmonary vasodilators and neuromuscular blocking agents in COVID acute respiratory distress syndrome

Figure 1 Flowchart of patients analyzed for the study. Intervention group was further subdivided (gray) by therapy combination for secondary analysis. ARDS: Acute respiratory distress syndrome; COVID: Coronavirus disease; IVd: Inhaled vasodilators; NMBA: Neuromuscular blocking agents; PCR: Polymerase chain reaction; P/F: Arterial oxygen partial pressure/fractional inspired oxygen; PPV: Prone position ventilation; SARS-CoV-2: Severe acute respiratory coronavirus 2.

Figure 2 Trends in secondary outcomes including ventilator parameters 7 days following initiation of prone ventilation. IVd: Inhaled vasodilators; NMBA: Neuromuscular blocking agents; P/F: Arterial oxygen partial pressure/fractional inspired oxygen; PPV: Prone position ventilation.
