What is the appropriate cuff inflation volume for a King LT Size 3 supraglottic airway?

The King LT Size 3 supraglottic airway is designed for patients weighing between 50-70 kg. The appropriate cuff inflation volume for this device is crucial to ensure proper sealing in the airway while minimizing the risk of injury to surrounding tissues.

For the Size 3 King LT airway, an inflation volume of 45-60 mL is recommended to create an effective seal in the pharynx, which helps maintain airway patency during ventilation. Using the correct volume is essential for effective ventilation and minimizing complications, such as inadequate lung expansion or air leak.

Using a volume below this range might lead to insufficient sealing and a risk of airway obstruction, while inflating the cuff beyond this recommendation could increase the risk of trauma to the surrounding structures or compromise airflow. Therefore, adhering to the recommended cuff inflation volume is critical for achieving optimal performance of the King LT Size 3 device in clinical practice.
