Fig. 2: Box-plots of proportion of additional iWOBinsp (CPAP 5 cmH2O).
From: Imposed work of breathing of 16 neonatal CPAP-devices using different mechanisms of CPAP generation

Inspiratory iWOB in a simulated 1000 g preterm (a) resp. 3000 g term (b) model (CPAP 5 cmH2O, see online supplement for 10 cmH2O and tables S3 and S4 for additional parameters); no iWOB determination feasible in term model for Medijet® and both models for Servo-i®.
