Abstract

There are many barriers to the movement of patients requiring mechanical ventilation and these patients are at risk for complications of immobility, especially pulmonary complications; so along with the use of mechanical ventilation in patients, we should take steps to create movements in them. The aim of this study was to determine the effect of chair position on respiratory parameters of patients undergoing mechanical ventilation. Materials & Methods: In this randomized clinical trial groups, 60 mechanically ventilated patients admitted to ICU in Besat Hospital of Hamadan with convenience sampling were studied. 30 patients were in chair position for half an hour (put the head of the bed at an angle of 70 degrees and foot of the bed at an angle of -75 degrees), and the other 30 patients (control group) were in initial position for half an hour (put the head of the bed at an angle of 30 degrees and knees straight). Respiratory parameters (respiratory rate, tidal volume, minute ventilation and arterial oxygen saturation) before and immediately after half-time were measured and recorded in two groups. The data were analyzed with SPSS16 to carry out paired t-test and t-test with significant level of P <0.05. Result: Research findings showed no significant difference in the respiratory control group index values. Respiratory rate before and after the chair position in the intervention group and between the two groups was not significantly different, But in the intervention group, increase in tidal volume, minute ventilation and arterial oxygen saturation was observed in the chair position that were statistically significant. Conclusion: Based on the results, it seems that placing the patient in the chair position can be effective in improving their respiratory parameters.
