Reevaluating 30 cmH₂O endotracheal tube cuff pressure: risks of airway mucosal damage during prolonged mechanical ventilation.

ABSTRACT:

Background

The optimal endotracheal tube (ETT) cuff pressure remains contentious. In the traditional consideration that the level 30 cmH₂O is considered safe, balancing the prevention of reflux aspiration against airway mucosal damage. Whether this pressure level can cause potential damage to the airway mucosa remains to be discussed.

Methods

Airway mucosa damage and structural changes at 30 cmH₂O were examined in patients under general anesthesia and in rabbit mechanical ventilation models. Prior to this, we also interviewed some anesthesiologists about the level of concern about ETT cuff pressure.

Results

A total of 634 valid questionnaires suggested that anesthesiologists generally do not pay enough attention to ETT cuff pressure and the avera
