Abstract

BACKGROUND AND OBJECTIVE:This study investigated the distribution of pressures within a model trachea, produced by five different tracheal gas insufflation devices. The aim was to suggest a suitable design of a tracheal gas insufflation device for clinical use.METHODS:Each device was tested using in...
