A comparison of endotracheal tube cuff pressures using estimation techniques and direct intracuff measurement.

Cuffed endotracheal tubes are one aspect of airway management designed to ensure safety, yet patients can be at risk for injury from underinflated and overinflated endotracheal cuffs. Tracheal pressures exceeding approximately 48 cm H2O impede capillary blood flow, potentially causing tracheal damage, and pressures below approximately 18 mm Hg may increase… (More)
