How much air should be used to inflate a laryngeal mask airway (LMA) cuff for adequate sealing?

• A. 10 cmH2O
• B. 30 cmH2O
• C. 60 cmH2O
• D. 90 cmH2O

Answer: (C)

The recommended pressure for inflating a laryngeal mask airway (LMA) cuff to achieve an adequate seal typically falls around 60 cmH2O. This pressure is considered optimal for ensuring that the cuff forms a proper seal in the laryngeal area while minimizing the risk of tissue damage or complications such as cuff leaks during positive pressure ventilation. When the cuff is inflated to this pressure, it helps to maintain airway patency during anesthesia and reduces the likelihood of aspiration. Overinflating the cuff beyond this pressure can lead to complications such as injury to the laryngeal tissues due to excessive pressure. Hence, the optimal sealing pressure is crucial for both effective ventilation and patient safety in clinical settings.
