The LMA Supreme Airway forms an effective first seal (oropharyngeal seal) with the oropharynx, which supports oropharyngeal seal pressures >27 cm H204,10-12 and an innovative second seal (esophageal seal) with the upper esophageal sphincter to isolate the respiratory tract from the digestive tract. This dual seal may be beneficial in patients with decreased thoracic compliance, in mild-tomoderately obese patients, and in certain procedures requiring mechanical ventilation where higher seal pressures are required, or in cases where intubation isn’t indicated but there is a small increased concern regarding regurgitation risk.

The LMA Supreme Airway incorporates design features intended to reduce the risk of aspiration. These include improved sealing characteristics versus first-generation devices and an integrated drain tube, which supports diagnostic testing to verify mask positioning, facilitates suction or decompression of the stomach, and enables expelled gastric content to bypass the pharynx in the unlikely event of active or passive regurgitation.
