Article Title: In vitro comparison of performance including imposed work of breathing of CPAP systems used in low-resource settings

doi: 10.1371/journal.pone.0242590

Figure Lengend Snippet: Imposed work of breathing for the Fisher and Paykel, Diamedica and first and second generation Pumani CPAP systems at flow rates of 6, 7, and 8 L/min and 8 cm H 2 O submersion depth are plotted. For the Medijet nCPAP generator, pressure cannot be set independently; results for the flow rates of 6, 7, and 8 L/min are plotted. (A) Imposed work of breathing for breath profiles of an infant (5.5 kg) (32 mL lung volume, sinusoidal breath pattern, RR = 60); (B) Imposed work of breathing for a term neonate (4 kg) (24 mL lung volume, sinusoidal breath pattern, RR = 67); (C) Imposed work of breathing for a preterm neonate (2.5 kg) (15 mL lung volume, sinusoidal breath pattern, RR = 67). Error bars represent standard deviation. Data in and Tables.

Article Snippet: The smaller neonatal and preterm neonate breath profiles are associated with comparable iWOB for the Fisher and Paykel and Diamedica devices.
