| description | Abstract Background Tracheal intubation exposes mechanically ventilated patients to serious pulmonary complications such as ventilator-associated pneumonia (VAP). This study was conducted to compare the efficacy of manual hyperinflation in supine versus lateral decubitus position on arterial blood gases (ABG) in patients with VAP. Forty-two patients with ventilator-associated pneumonia with age range from 40 to 60 years were selected. They were randomly divided into two equal groups: group A who received manual hyperinflation from supine position and group B who received manual hyperinflation from lateral decubitus position (upper most affected). Both groups received respiratory physiotherapy. The patients received 2 sessions per day for 6 days. Outcome measures were arterial blood gases (PaO2, PaCO2, PaO2/FiO2, and SaO2). They were assessed before the 1st morning session (pre), at day 3 (post 1), and at day 6 (post 2). Results After sessions, significant changes of measured variables (PaO2, PaCO2, PaO2/FiO2, and SaO2) were obtained in both groups (P < 0.05, in all variables) and by comparison between groups post-intervention; a significant difference was observed between both groups in measures of oxygenation in favor of group B (P < 0.05), whereas there was a non-significant difference in the PaC02 between both groups (post 1 P = 0.52 and post 2 P = 0.33). Conclusion It was concluded that effect of the bag squeezing on arterial blood gases in patients with ventilator-associated pneumonia from lateral decubitus position was more effective than from supine position.
