Abstract: Postural drainage is one of the most common techniques used by physiotherapists in the management of patients with excessive secretions. Desaturation occurs at times when patients were placed in a head-down postural drainage position. This study was a one group pretest-posttest design which aimed to evaluate the effect of the head-down position on the static compliance of the respiratory system and oxygen saturation in mechanically ventilated patients suffering from pneumonia. Fifteen adult patients diagnosed with unilateral pneumonia and under mechanical ventilation in the intensive care unit of United Christian Hospital were recruited. Each patient was positioned in the zero or twelve degrees head-down lateral decubitus lying position for fifteen minutes. Static lung compliance and oxygen saturation were measured by the Adult Star 2000 ventilator and pulse oximeter respectively. Comparison of the group means by Paired t-test and correlation evaluation by Pearson product-moment coefficient of correlation were employed for data analysis. Results showed that the static compliance of respiratory system decreased significantly (p < 0.001) in the twelve degrees head-down position. However, no significant difference in oxygen saturation was found upon postural change. There was no correlation between static lung compliance and oxygen saturation. It was concluded that a head-down position could decrease lung compliance and precaution should be taken particularly when applying head-down postural drainage to mechanically ventilated patients in the intensive care unit.
