Effect of position and positive pressure ventilation on functional residual capacity in morbidly obese patients: a randomized trial

ConclusionIn awake morbidly obese volunteers, an increase in the FRC is observed when spontaneous ventilation at zero inspiratory pressure is switched to positive pressure. Compared with S positioning, the BC position had no measurable impact on the FRC. The RT position resulted in an optimal FRC.Trial registrationclinicaltrials.gov (NCT02121808).
