Figure 7From: Effects of the components of positive airway pressure on work of breathing during bronchospasmChange in end-expiratory lung volume (EELV) after 10 cmH2O inspiratory positive airway pressure (IPAP), expiratory positive airway pressure (EPAP), and continuous positive airway pressure (CPAP) before and after methacholine infusion. For the same positive airway pressure condition, ΔEELV was significantly less (*P < 0.05) after methacholine.Back to article page
