机械通气气管导管气囊压力的临床研究

摘要

目的 寻求机械通气气管导管理想气囊压力的管理方法.方法 应用最小闭合容量技术注气测量机械通气患者气管导管气囊压力,并统计分析.结果 实际测得的气囊压力范围为10～42cmH2O,与指南推荐气囊压力25～ 30cmH20差异较大.结论 应用最小闭合容量技术个体化测量气囊压力并定时校正,可有效预防气道黏膜损伤.%Objective To explore ideal methods of managing cuff pressure of endotracheal tube cuff inflation. Methods Cuff pressure was measured by minimum closing volume, and the datas were statistically analysed. Results Actual cuff pressure ranged from 10～42cmH2O and was different from recommended cuff prcssure(25～30cmH2O). Conclusion Applying minimum closing volume technology to test the cuff pressure individually and calibrating regularly can effectively prevent airway injury.
