摘要
目的：判断机械通气患者气管套管气囊压力是否合适。
方法：40例经口气管插管和15例气管切开行机械通气患者的气囊压力和注气容积进行测量。
结果：实际气管插管患者气囊压力为（59．3±217）cmH2O．明显高于推荐压力值；实际注入气体量明显高于推荐压力所需注入容积（P＜0．05）。
结论：临床上根据经验和手感来确定气管导管气囊压力和注气量偏高，应对机械通气患者的气管套管压力和注气量进行测量和调整．以减少气管套管对气管粘膜的损伤。
Objectives： To evaluate tracheal tube cuff pressure in the patients with mechanical ventilation.
Methods： Forty patients with intubation and fifteen patients with tracheostomy were studied. Both gas volume and pressure of tube cuff were measured by control inflator.
Result： The actual inflated volume and pressure were higher than the recommended volume and pressure （P〈0.05）.
Conclusion： The cuff pressure should be measured regularly in order to avoid tracheal mucosa injury for long time residence within the trachea.
