Background: Manual expiratory rib cage compression technique is one of the most practiced chest physiotherapy technique in mechanically ventilated patients in intensive care unit Aim of the study: to detect the effect of manual rib cage compression on blood gases in mechanically ventilated patients Patient and Methods: forty adult patients on pressure controlled mechanical ventilation from both gender participated in this study , their ages ranged from 40 to 50 years old and randomly distributed into two equal groups A (control group ) and B (Study group). Group (A): twenty mechanically ventilated patients received traditional physiotherapy (positioning, percussion, vibration and suctioning) Group (B): twenty mechanically ventilated patients received manual expiratory rib cage compression technique in addition to the same traditional treatment. Each patient received two sessions per day for 3 days, both groups assessed before and after treatment regarding arterial blood gases parameters (PH, SaO2, PaO2, and PaCo2). Results: there were significant increase after treatment in PaO2 and SaO2 compared to before-treatment within control group with improvement percentage 39.65% and 3.15% and study group with improvement percentage 46.85% and 4.80 %. But, no significant differences (P>0.05) between before and after treatment in pH and PCO2 within control group and study group. And Between both groups indicated no significant differences (P>0.05) at before and after treatment in pH, PCO2, PO2, and SaO2 between control group and study group
