Cuff pressure on tracheal tubes


Q; What should be the optimal pressure applied to tracheal tube cuffs?


A; 20 - 30 cm H2O.

Cuff pressure should not exceed the capillary occlusion pressure of the tracheal wall. The concern is that with increasing cuff pressure beyond given threshold, it may compromise mucosal blood supply and may result in subglottic stenosis. Tracheal mucosal ischemia occurs when endotracheal tube cuff pressure exceeds above 34 cm H2O (some suggests it is safe till 40 cm H2O).
