During mechanical ventilation, endotracheal tube cuff pressure should be maintained within proper range. We investigated the effect of frequent adjustment on cuff pressure in 27 mechanically ventilated patients. Cuff pressure was recorded every 2 h and was adjusted to 24 cmH2O each time. We found that cuff pressure was decreased by 4.9 ± 2.9 cmH2O from the target value. Cuff pressure decreased to less than 20 cmH2O in 45% of measurement occasions 2 h after adjusting it to 24 cmH2O.
在机械通气过程中，应将气管内导管套囊压力维持在适当范围。我们研究了 27 例机械通气患者频繁调整套囊压力对其的影响。每 2 h 记录一次套囊压力，并每次将其调整至 24 cmH2O。我们发现，套囊压力从目标值下降了 4.9 ± 2.9 cmH2O。将套囊压力调整至 24 cmH2O 2 h 后，有 45%的测量时机其压力降至 20 cmH2O 以下。
