Positive Pressure Ventilation with the ProSeal Versus Classic Laryngeal Mask Airway: A Randomized, Crossover Study of Healthy Female Patients

Abstract
The ProSeal and classic laryngeal mask airways are equally effective ventilatory devices in healthy female patients at tidal volumes of 8 and 12 mL/kg with the cuff semi- or fully inflated, but leakage of small volumes of air from the mouth occurs more frequently with the laryngeal mask airway.
