Predictive Factors for Failure of Noninvasive Ventilation in Adult Intensive Care Unit: A Retrospective Clinical Study

Table 2

Multivariate analysis of the risk factors for noninvasive ventilation failure.

Variables	OR and 95%CI	value
IBW (kg)	1.110(1.027, 1.201)	0.009
HR-MAX (bpm)	1.024(1.004, 1.046)	0.021
RR-MIN (bpm)	1.198(1.051, 1.365)	0.007
T-MAX (°C)	1.838(1.038, 3.252)	0.037

Data were presented as median (95% of confidence interval, CI); IBW, ideal body wight; HR-MAX, the maximal heart rate during NIV period (beats per minute, bpm); RR-MIN, the minimal respiratory rate during NIV period (breath per minute, bpm); T-MAX, the highest body temperature during NIV period.
