Preoxygenate the patient with 100% oxygen via a nonrebreather mask, as time allows.

Choose the appropriate size of laryngeal mask airway (LMA).

Check the LMA cuff for leaks.

Deflate the cuff of the LMA completely against a flat surface.

Apply a water-soluble lubricant generously to the posterior surface of the mask.

Administer sedation when indicated.

Position the patient.
