From: A new reservoir-based CPAP with low oxygen consumption: the Bag-CPAP
Evolution of pulse oximetry (SpO2), respiratory rate (RR), and modified Borg dyspnea scale after initiation of Bag-CPAP in patients with acute hypoxemic respiratory failure. Readings of SpO2 (panel A), respiratory rate (panel B), and modified Borg dyspnea scale (panel C) were collected at baseline under conventional oxygen therapy before Bag-CPAP initiation (red circles), within 10 min after Bag-CPAP initiation (T0; blue circles), and after 30, 60, 120, 180, and 240 min of Bag-CPAP treatment (T30, T60, T120, T180 and T240, respectively; blue circles). * denotes p value < 0.05
