Effects of Nitrous Oxide on Volume and Pressure of Endotracheal Tube Cuffs

Abstract

The effects of nitrous oxide on endotracheal tube cuff gas volumes and pressures were determined with 50 size 32–40-Fr Foregger endotracheal tubes fitted with fluted latex rubber cuffs. The cuffs were inflated with 5,10, or 15 ml of air and then exposed to 100,75,50, or25 per cent nitrous oxide in o
