Introduction: Measuring arterial blood gas, which is performed in different parts of the body, plays an important role in clinical evaluation.
Aim: The present study was conducted to determine the effect of position change on arterial oxygen saturation in different parts of the body, in cardiac and respiratory patients.
Materials and Methods: The present randomised clinical trial was conducted on 169 hospitalised patients admitted to 22 Bahman Hospital of Gonabad in 2016. Patients were selected through convenient sampling, then were randomly assigned into three groups of cardiac patients, respiratory patients and control. Initially, the patient was placed in a semi-fowler’s position for 15 minutes; then, arterial oxygen saturation was measured at three points i.e. the auricle, fingertip and tip of the greater toe simultaneously. Then, the patient was placed in the supine and prone positions and the arterial oxygen saturation was measured following the same protocols of the former position. Collected data were analysed at a significance level, p-value less than 0.05 by SPSS-version 20 through the analysis of variance with repeated measures, independent t-test and Pearson correlation coefficient.
Results: The mean oxygen saturation percentage has statistically significant difference at different positions (p=0.016). It was also found that there was a significant difference between the mean oxygen saturation on three different points i.e. fingertip, auricle and the tip of the greater toe (p<0.001).
Conclusion: The arterial oxygen saturation in the semi-fowler’s position and the auricular point were higher in the three groups of patients with and without cardio-respiratory disorder than other positions and body points.
