對於放置氣管內管，使用呼吸器的加護病房病人，成功的痰液清除和通氣是一項重要的任務。文獻及臨床經驗皆顯示手動式高度充氣擴肺術可以改善使用呼吸器病人的痰液清除和通氣。然而，很少實證研究支持臨床上常規使用手動式高度充氣擴肺術。本研究目的是驗證手動式高度充氣擴肺術用在急性呼吸衰竭肺擴張不全病人，痰液清除和通氣之成效。
本研究使用控制、隨機、單盲的實驗性研究設計。收案場所在北部某醫學中心的胸腔科加護病房。以隨機決定研究對象進入研究順序的方式，共有28位研究對象完成本研究，實驗組和對照組各14位。實驗組個案接受呼吸器設定型式和手動式高度充氣擴肺術，對照組個案則僅接受呼吸器設定型式。手動式高度充氣擴肺術壓力20cm H2O，每日執行三次，每次20分鐘，共2天。治療效果評值項目共有八項，包括，病患痰液濕/乾比，痰液黏稠度，潮氣容積，最大吸氣壓，動脈血氧分壓/吸入氧濃度，胸部X光影像，動態順應性和淺快呼吸指標。所有研究對象皆每天評值病患痰液濕/乾比、痰液黏稠度、潮氣容積、最大吸氣壓、動態順應性和淺快呼吸指標；每三天評值動脈血氧分壓/吸入氧濃度和胸部X光影像，研究結果如下：
一、痰液清除方面，實驗組病患在痰液黏稠度的得分改變量較對照組進步，達到統計上顯著差異，p值為0.011。兩組病患在濕/乾比的進步程度無顯著差異。
二、通氣方面，實驗組病患在淺快呼吸指標的得分改變量較對照組改善，此項改變量隨著時間遞增，達到統計上顯著差異，在第二天和第三天的p值分別為0.062和0.050。達到統計上顯著差異。兩組病患在潮氣容積、最大吸氣壓、動脈血氧分壓/吸入氧濃度、動態順應性和胸部X光影像的進步程度無顯著差異。
經由本研究顯示實施手動式高度充氣擴肺術可以改善急性呼吸衰竭病人的痰液清除和通氣。

Regarding in the intubated ICU patients receiving mechanical ventilation, successful sputum clearance and ventilation are an important task. The literature and the clinical experience all demonstrated the effect of MH on the patients receiving mechanical ventilation, it may improve sputum clearance and ventilation. However, there are few emperical studues to support its routine use in clinical practice. The purpose of this study was to examine the effectiveness of MH on sputum clearance and ventilation on Atelectasis in Patients With Acute Respiratory Failure.
A controlled, randomized, single blind, experimental design was used. Each patient was assigned a random numder upon entering the research project, which allowed randomly allocation to two groups: experimental group and control group. The sample were collected in the ICU of a Medical Center in northern Taiwan. A total of 28 patients joined the study in two groups, i.e., experimental group and control group, 14 patients in each group. Case from the experimental group received ventilation support and additional manual hyperinflation while cases from the control group were only received ventilation support. Patients in experimental group received the manual hyperinflation at a peak airway pressure of 20 cm H2O once of 20 minutes in 3 times per day for two days.
Outcome measurements were evaluated by noting changes in the patient,s score in dry/wet ratio of sputum, sputum viscosity, tidal volume, maximal respiratory pressure, PaO2/Fio2, upper chest X-ray film, dynamic lung compliance and the index of rapid shallow breathing.
Dry/wet ratio of sputum, sputum viscosity, tidal volume, maximal respiratory pressure, dynamic lung compliance and the index of rapid shallow breathing were assessed every day. PaO2/ Fio2 and upper chest X-ray film were assessed once every three days. Upon giving the conclusions are as follows:
一、For the sputum clearance, patients from the experiment group were significant improvement than those from control group in terms of sputum viscosity(p=0.011);while patients from both group were no significant difference in dry/wet ratio of sputum.
二、For the ventilation, patients from the experimental group were significant improvement than those from control group in terms of the index of rapid shallow breathing on second day and third day(p=0.062,p=0.050); while patients from both groups were no significant difference in terms of tidal volume, maximal respiratory pressure, PaO2/Fio2,dynamic lung compliance and upper chest X-ray film.
This study showed MH improved sputum clearance and ventilation in patients with acute respiratory failure.
