Secondary outcome
The rate of successful intubation on the first attempt without
physiological instability was higher in the NIPPV group, although the
difference was not significant (p = 0.100). The bradycardia rate and
severe desaturation were significantly higher in the standard care group
(p < 0.002 and p < 0.020, respectively). The lowest
SpO2 level and the lowest heart rate during the
procedure were significantly higher in the intervention group (p
< 0.001 and p < 0.001, respectively). The rate of
SpO2 dropping below 80% and below 90% was higher in
the control group (p < 0.014 and p < 0.002,
respectively). The median duration of severe desaturation was
significantly shorter (p = 0.043) in the NIPPV group (10 s) compared to
the standard care group (20 s) (Table 2).
