Theses and Dissertations
This study utilized a quasi-experimental pretest-posttest design that compared the effect of body position changes on arterial oxygen saturation in obesity as measured noninvasively by pulse oximetry. The null hypothesis, that there would be no difference between oxygen saturation values measured by pulse oximetry with position change from sitting to supine in obese subjects as compared to nonobese subjects, was tested. Fourteen obese, American Society of Anesthesiologist (ASA) physical class status II subjects and 14 nonobese ASA physical class status I subjects were included in the sample population. Thirteen of the obese subjects were further classified as morbidly obese. After …
