Aim: This study was conducted to compare the effect of manual hyperinflation and rib springing technique in mechanically ventilated patients with lung collapse. Martials and methods: forty mechanically ventilated patients with lung collapse who were admitted to the intensive care unit participated in this study. Their ages ranged from 30 to 40 years and randomly distributed into two equal groups: group (A and B). Group (A): twenty patients were received manual hyperinflation in addition to their traditional chest physical therapy program (nebulization / positioning / vibration / percussion / suctioning). Group (B): twenty patients were received rib springing technique in addition to the same traditional treatment as group (A). Each patient in both groups assessed before treatment and reassessed after 4 successive sessions at a rate of one session per day regarding PaO2 and Respiratory rate. Results: In this study there was a statistical increase in PaO2 of the group A post treatment compared with that of the group B post treatment (p = 0.02). There was no alteration in RR post-chest PT when compared to pre-chest PT in both groups. Conclusion: Manual hyperinflation and Rib spring technique both must be added to chest physical therapy management programs in mechanically ventilated patients with lung collapse.
