Abstract
A laryngeal mask airway (LMA) device is provided, which includes an inflatable annular cuff, a backplate attached to the cuff, and an airway tube. The cuff, when disposed in free space, is characterized by a pressure-volume curve that represents the pressure in the cuff when inflated to different volumes of the cuff that include a low-pressure volume corresponding to a low pressure of 10 cm H2O. The pressure-volume curve includes (a) a local maximum pressure at a medium volume of the cuff between 1.25 and 2.4 times the low-pressure volume, wherein the local maximum pressure is between 15 and 120 cm H2O, and (b) respective high-volume medium pressures corresponding to all high volumes of the cuff that are between 2.5 and 3 times the low-pressure volume. Each of the high-volume medium pressures is between 15 cm H2O and 99% of the local maximum pressure. Other embodiments are also described.
