Multivariable logistic regression for the effect of implementation of apneic oxygenation use on moderate oxygen desaturation<80%

Variable	Odds Ratio	95% CI	p-value
Implementation of apneic oxygenation
Pre-intervention	Reference
Post-intervention	0.55	0.34–0.88	0.013

Total N=1,368. Five Encounters are missing device data.

Goodness-of-fit test Chi(2)=18.07, p=0.259.

Covariates were selected based on the change in patient and practice between pre- and post-intervention phases.

^*Other device includes laryngeal mask airway, fiberoptic bronchoscope or combination of two devices.
