  1. The difference in imposed work of breathing between CPAP/PS and CPAP (∆WOBimp) was stated as dependent variable. The measured WOBimp during CPAP/PS was noted as baseline WOBimp. The effect of baseline WOBimp, endotracheal tube size (ETT size), inspiratory time (Tinsp), peak inspiratory flow rate (PIFR) and expired tidal volume (VTe) on ∆WOBimp was studied
  2. A p value of < 0.05 (*) was denoted as statistically significant
