Evaluation of Intratracheal Cuffs for Aeromedical Evacuation.

Abstract

Conventional, low-residual-volume intratracheal cuffs exert possible trachea damaging pressures at ground level and definitely damaging pressures upon ascent to 8,000 ft. Also, these cuffs exert excessively high pressures with decompression to 35,000 ft. Cuff/tracheal pressure exerted by a foam-type cuff was relatively unaffected by altitude changes, but depended on critical selection of the proper size tube. In contrast, several types of low-pressure, large-residual-volume cuffs with a control balloon maintained a satisfactory cuff/tracheal pressure at all altitudes. (Author)
