Fig. 1From: Clinical risk factors for increased respiratory drive in intubated hypoxemic patientsAssociation between severity of lung injury (ventilation/perfusion mismatch) and P0.1. Results of bivariate analyses show that P0.1 was inversely associated to PaO2/FiO2 and directly associated with ventilatory ratio, indicating that impairment in oxygenation and CO2 clearance are clinical risk factors for increased respiratory driveBack to article page
