Table 1. Airway Sealing Pressure and Fiberoptic Position for the Laryngeal Mask Airway (LMA) and ProSeal Laryngeal Mask Airway (PLMA) with Increasing Cuff Volume

Data are mean (95% confidence interval) or numbers. Pressures are in cm H2O.

* Airway sealing pressure > 40 cm H2O in 5/60 with the LMA and 22/60 with the PLMA.

4 = only vocal cords visible; 3 = vocal cords plus posterior epiglottis; 2 = vocal cords plus anterior epiglottis; 1 = vocal cords not seen.
