Inflate the cLMA cuff. Take care not to overinflate the cuff, as this may lead to a poorer seal, which increases the risk of pharyngolaryngeal and nerve injuries.

Intracuff pressures should be routinely monitored to ensure they do not exceed 60 cmH₂O. The 'recommended' volumes of air (printed on the tube side) are in fact maxima, and if a pressure monitor is not available, it is wise to start with half that volume.

When using nitrous oxide as part of the anaesthetic, cuff pressure rises for approximately 20-30 min as nitrous oxide diffuses to equilibrium. Therefore, the cuff pressure should be rechecked at this time.
