Flow chart. Weaning success was defined as weaning to low-flow nasal cannula, room air, or oxygen hood for 7 d. Weaning failure was defined as returning to CPAP or high-flow nasal cannula within 72 h.

Comparison of SpO2 histogram distribution pre-transition (A) and post-transition (B) between successful and failed transition groups. SpO2 histogram was recorded for the 24-h periods pre- and post-transition from either CPAP or high-frequency nasal cannula to low-frequency nasal cannula or room air. Data are expressed as mean ± SD. * P < .05.

Comparison of SpO2 histogram distribution pre-transition (A) and post-transition (B) of subjects transitioned from CPAP or high-frequency nasal cannula (HFNC) to low-frequency nasal cannula or room air. Data are expressed as mean ± SD.

Correlation between percent change in FIO2 post-transition and percentage of time with SpO2 <86% (A) and percentage of time with SpO2 >95% (B). For each subject, the percentage change in FIO2 post-transition was calculated. The Spearman's rank correlation test was used to calculate the correlation coefficient between percent change in FIO2 and percentage of time with SpO2 <86% and SpO2 >95% for the 24-h periods pre- and post-transition.
