Abstract

|
|
Purpose: This study examined the effects of chest physiotherapies, high-frequency chest wall oscillation and
manual percussion, in mechanically ventilated patients.
Methods: This repeated measure-experimental study was done with 11 ICU patients with ventilators. Each patient received manual percussion 5 min (method 1), high-frequency chest wall oscillation 5 min (method 2), and 10 min (method 3) at 2 hour intervals. After each chest physiotherapy, amount of sputum collected was measured. Systolic blood pressure (SBP), heart rate (HR), tidal volume (TV), dynamic lung compliance and peripheral oxygen saturation recorded at prior to, immediately, 10 min, 20 min, 30 min, 60 min, 120 min after each chest physiotherapy. Data were analyzed with Kruskal-Wallis test and Wilcoxon signed-rank test.
Results: There was no significant differences in sputum amount for each method. However, 10 min after the intervention, there were significant increase in SBP (p=.024), HR (p=.013), and TV (p=.007) in method 2, and significant increase in SBP (p=.032) and HR (p=.012) in method 3, and SBP (p=.008) in method 1.
Conclusion: The effect of the two chest physiotherapies for mechanically ventilated patients on sputum amount, hemodynamic indicators and ventilation is not different. When applying high-frequency chest wall oscillation therapy, providers should observe heart rate of patients carefully.
