Background: The patients under mechanical ventilation are involved in immobility and its complications. Patient's position change is an important nursing intervention to prevent complications due to immobility. Although, many studies have reported the effect of body position on pulmonary ventilation and perfusion but yet, there are more questions on the effect of kinetic and static positions on cardiopulmonary indices.
Materials and Methods: This is a clinical trial on 16 patients under mechanical ventilation hospitalized in central ICU of Al-Zahra Hospital. Method of sampling was continue convenience and tool of data collection was check list, and was used content validity for validity and pilot study for reliability. Intervention process consist of those patients before of each position first received basal position (supine), then with random order were positioned either kinetic-static (prone) or static (Prone-kinetic). Remain duration in each position was 30 minutes and cardiopulmonary parameters were measured in basal position and 15 minutes intervals then after for two times after each position. Statistical analysis was done with descriptive and inferential statics (ANOVA repeated measurement and T Paired).
Results: In both of positions was shown increased SPO2 and decreased static compliance that SPO2 increase after static position and static compliance decrease after administrating kinetic position were statistically but no significant in cardiopulmonary parameters (RR, TV and airway R) in before and after both of positions.
Discussion: Whereas no significant clinical cardiovascular change occurred following kinetic or static positioning. It can be concluded that both positioning method; could be used safely in mechanically ventilated patients. Relative benefits of static position in decreased of airway resistance; increase of TV and SPO2 may be considered in mechanically ventilated patients.
