Automatic endotracheal tube cuff inflator and continuous pressure monitor/controller.
Endotracheal tube cuff pressure over 30 cm of water has been found to occur in about 50% of cases where cuff inflation was performed without monitoring, using pilot balloon palpation, minimal leak, or minimal occlusive volume techniques1. The incidence of post operative respiratory complications such as cough, sore throat, hoarseness, blood-streaked expectoration, and even tracheal stenosis is ...
متن کاملLaboratory evaluation of 4 brands of endotracheal tube cuff inflator.
INTRODUCTION Routine measurement of endotracheal tube (ETT) cuff pressure is a standard in respiratory care, and several devices are available for measuring ETT cuff pressure. Yet an informed choice in the buying process is hindered by the present paucity of unbiased, comparative data. METHODS Four brands of cuff inflator were tested: Posey Cufflator, DHD Cuff-Mate 2, Rüsch Endotest, and SIMS...
متن کاملRapid pressure compensation by automated cuff pressure controllers worsens sealing in tracheal tubes.
BACKGROUND Cyclic redistribution of air within the cuff during respiratory pressure changes creates a self-sealing mechanism which allows tracheal sealing, despite tracheal airway pressure being above baseline cuff inflation pressure. The aim of the present study was to investigate the effect of continuous automated cuff pressure regulation on tracheal sealing during cyclic respiratory pressure...
متن کاملDirect measurement of mucosal pressures exerted by cuff and non-cuff portions of tracheal tubes with different cuff volumes and head and neck positions.
We measured directly mucosal pressures against the cuff and non-cuff portions of the tracheal tube in different head-neck positions and tested the reliability of calculated mucosal pressures, in vivo intracuff pressures and cuff volume as determinants of directly measured mucosal pressures. We studied 10 anaesthetized, paralysed adult patients. An 8.5-mm, high volume, low pressure PVC tracheal ...
متن کاملEfficiency of a pneumatic device in controlling cuff pressure of polyurethane-cuffed tracheal tubes: a randomized controlled study
BACKGROUND The primary objective of this study was to determine the efficiency of a pneumatic device in controlling cuff pressure (Pcuff) in patients intubated with polyurethane-cuffed tracheal tubes. Secondary objectives were to determine the impact of continuous control of Pcuff, and cuff shape on microaspiration of gastric contents. METHODS Prospective randomized controlled study. All pati...
