Changes in Pediatric-Sized Endotracheal Tube Cuff Pressure With Elevation Gain: Observations in Ex Vivo Simulations and In Vivo Air Medical Transport

摘要

Objectives Prolonged excessive endotracheal cuff pressure greater than 30 cmH(2)O is thought to cause ischemic airway injury. Excessive cuff pressure with altitude gain during air medical transport has been previously described in adult patients. It is poorly understood how pediatric-sized endotracheal tube (ETT) cuffs behave with atmospheric pressure change during flight.
