How much do you inflate the Melker cannula during a cricothyrotomy?

The correct volume for inflating the Melker cannula during a cricothyrotomy is 10 mL. This specific amount is based on the design and intended functionality of the Melker cannula, which is a tool used for establishing an airway in emergency situations. Inflating the cuff of the cannula to this level ensures adequate sealing within the trachea, allowing for effective ventilation while minimizing the risk of aspiration or leakage of air.

Inflating to 10 mL strikes a balance between ensuring that the cuff is sufficiently filled for proper positioning and maintaining safety and comfort for the patient. Over-inflation could lead to complications such as tracheal injury or inadequate blood supply to the surrounding tissue due to excessive pressure.

In emergency medical protocols, adhering to the recommended inflation volume is essential to ensure the efficacy of the procedure and the safety of the patient during critical situations.
