EPO2-PV: Evaluation of Pre-Oxygenation Conditions in Morbidly Obese Volunteer: Effect of Position and Ventilation Mode

Canada20 participantsStarted 2014-04

Plain-language summary

The risk of complications associated with airway management in obese patients is significant. The results of pre-oxygenation allow a prolonged non-hypoxic apnea time for the clinician. The increase in FRC and non-hypoxic apnea time is correlated. The best condition to accomplish the pre-oxygenation in morbidly obese patient is still undetermined in medical literature. This study is designed to evaluate the effect of different positions combined with different ventilation modes during the pre-oxygenation phase of anesthesia's induction. EPO2: PV will evaluate the effect of different combinations of positions and ventilation modes on pulmonary volumes (mainly functional residual capacity) in a morbidly obese volunteer.
