Abstract

Background: Chest physiotherapy is a critical aspect of the treatment of mechanically ventilated patients . Expiratory rib cage compression is considered one of the bronchial hygiene techniques that is commonly applied among mechanically ventilated patients. Aim: This study aimed to investigate the effect of expiratory rib cage compression on oxygenation and ventilation among mechanically ventilated patients. Method: A quasi-experimental research design was used to conduct this study at intensive care units of the Mansoura Emergency Hospital. A sample of 64 patients was randomly assigned into two equal groups (n = 32). The intervention group received expiratory rib cage compression, and the control group received percussion only. Respiratory status assessment sheet and expiratory rib cage compression outcome evaluation tool were used to collect data for this study. Results: There was highly statistically significant difference between the control and intervention groups regarding tidal volume, the oxygenation parameters as PaO2, SaO2, SpO2, and the pulmonary oxygenation capacity index (PaO2/FiO2 readings). While no significant differences were found in ventilation parameters as PaCO2 and HCo3. Conclusion: Expiratory rib cage compression are efficient in improving the arterial oxygenation parameters and it is easily applied in intensive care units. Recommendations: Expiratory rib cage compression should be used in combination with conventional chest physiotherapy techniques as a part of nursing care for mechanically ventilated patients. Furthermore, other studies on a larger number of Egyptian critical care units in different hospitals may enrich significant findings.
