Acute Response of Manual Hyperinflation In Addition To Standard Chest Physiotherapy on Critically Ill Mechanically Ventilated Patients

Background: Physiotherapists use manual hyperinflation (MHI) as a treatment for the recruitment of collapsed lung and mobilization of excess pulmonary secretions .Purpose: To investigate the acute effect of manual hyperinflation (MHI) on oxygenation and volume of secretions cleared in mechanically ventilated patients. Subjects and Methods: Manual hyperinflation was delivered in 30 medically stable, mechanically ventilated patients . patients were randomly selected from Cairo university hospitals (critical care department). Their ages ranged from 50 to 60 years .The study group A received both manual hyperinflation and standard chest physiotherapy while control group B received standard chest physiotherapy only. Oxygenation parameters were recorded before and after 30 minutes of treatment while secretion volume was recorded after 30 minutes of treatment. Results: The results of this study revealed statistically significant improvement in oxygenation parameters and the amount of drained chest secretions in patients of both groups which was highly significant in favor of study group A with P value ≤ 0.05. Conclusion: Use of manual hyperinflation in combination with standard chest physiotherapy is a beneficial method to clear lung secretions and improve oxygenation parameters in mechanically ventilated patients .
