A: Work of breathing before and after nebulized terbutaline delivered via standard nebulization method versus delivered during continuous positive airway pressure (CPAP). A: Work of breathing before and after nebulized terbutaline delivered via standard nebulization method versus delivered during continuous positive airway pressure (CPAP). WOB decreased similarly with the 2 methods (P = .06). B: PaO2 and PaCO2 after nebulized terbutaline delivered via standard nebulization method versus delivered during CPAP. PaO2 was significantly higher with CPAP nebulization. PaCO2 was not significantly different between the 2 methods. Arnaud W Thille et al.
