Abstract:

AbstractBackground: Manual hyperinflation and expiratory rib cage compression are methods of chest physiotherapy. They
are commonly applied but their value and their early utilization managing mechanically ventilated remain questionable.
The purpose of the study was to investigate the effects of manual hyperinflation with rib cage compression and
endotracheal suctioning on arterial blood gas parameters in mechanically ventilated patients.
Results: Seventy mechanically ventilated patients at a teaching hospital in Egypt were assigned to the clinical trial
study. The age of more than half of the studied samples ranged between 60 and 69 years with a mean age of 53.64 ±
16.44 years. Initially, the ABG parameters were assessed. Then, the patients were exposed to manual hyperinflation for
5 min and 20 min external expiratory chest compression followed by endotracheal suctioning. Later, ABG parameters
were assessed again and compared to the initial one. The findings revealed significant differences in ABG parameters
before and after completion of MHI and ERCC and ETT suctioning in relation to PaO2
(t = 3.892) and SaO2
(t= 5.904).
Also, it showed significant improvement in PaO2
and SaO2
after the completion of interventions, while no significant
differences were found in other ABG parameters. This study was registered retrospectively with an ISRCTN number
39983 on 5/6/2021.
Conclusion: Applying manual hyperinflation with rib cage compression and endotracheal suctioning improved
mainly the arterial oxygenation parameters in mechanically ventilated patients despite no significant changes
observed in other ABG parameters.
