What is the recommended pressure for cuff inflation in endotracheal tubes?

The recommended pressure for cuff inflation in endotracheal tubes is generally set between 20-30 cm H2O. This pressure range is optimal for ensuring a proper seal around the trachea while minimizing the risk of complications such as tracheal injury or ischemia to surrounding tissues. Maintaining the cuff pressure within this range helps to prevent both airway leaks, which can lead to inadequate ventilation, and excessive pressure that could erode tracheal mucosa, increasing the risk of tracheitis and other airway complications.

Using pressures outside of this recommended range can lead to significant clinical issues. For example, pressures below 20 cm H2O may not effectively prevent aspiration or air leaks, compromising ventilation effectiveness. On the other hand, pressures exceeding 30 cm H2O can increase the risk of damage to the trachea and surrounding structures due to prolonged pressure, leading to severe complications. Therefore, adhering to the recommended cuff inflation pressures is crucial for patient safety and effective airway management.
