Performance of low-pressure cuffs. An experimental evaluation

S M Mehta. Ann R Coll Surg Engl. 1982 Jan.

Abstract

A study was carried out in vitro to determine the minimum intracuff pressure needed to produce no-leak ventilation and prevent aspiration in Portex Profile and Searle Medical Sensiv endotracheal tubes. The mean pressures required to produced no-leak ventilation were 4.16 and 1.06 kPa respectively and the mean pressures at which aspiration occurred were 2.93 and 0.54 kPa respectively. The implications of these findings are discussed and recommendations are made regarding cuff specifications.
