Summary
This study tested whether sleeping in a semi-upright position (45-degree angle) after surgery could prevent sleep apnea from getting worse. 164 adults with sleep apnea who were having elective inpatient surgery took part. Half slept semi-upright and half slept flat on their backs. The researchers measured breathing problems on the second night after surgery.
