Abstract

BACKGROUND

Manual hyperinflation is a treatment technique commonly used by physiotherapists in intensive care units to reverse or prevent atelectasis and mobilize airway secretions in intubated patients. The aim of this study was to determine which of the Magill (Rusch Manufacturing Ltd, Craigavon, UK) or Mapleson-C (CIG DF 655, CIG Medishield, Sydney, Australia) manual hyperinflation circuits was theoretically more effective at mobilizing secretions.

METHODS

A semi-blinded crossover study of 12 physiotherapists with tertiary level intensive care unit experience was conducted on a benchtop model. The order of circuits and compliance settings was randomized.

RESULTS

The Mapleson-C circuit produced a significantly faster peak expiratory flow (F[1, 210]=14.51, P < or = .01) and smaller inspiratory to expiratory flow ratio (F[1, 210]=28.44, P < or = .01) than the Magill circuit regardless of compliance settings.

CONCLUSION

The results of this study suggest that the Mapleson-C manual hyperinflation circuit may be more effective at mobilizing secretions.

摘要

背景

手动过度充气是重症监护病房物理治疗师常用的一种治疗技术，用于逆转或预防肺不张，并在插管患者中移动气道分泌物。本研究的目的是确定 Magill（Rusch Manufacturing Ltd，Craigavon，英国）或 Mapleson-C（CIG DF 655，CIG Medishield，悉尼，澳大利亚）手动过度充气回路在理论上哪个更有效地移动分泌物。
