Influence Of Head Position On Obstructive Sleep Apnea Severity
Zhu K, Bradley TD, Patel M, Alshaer H, Sleep and Breathing. 2017; Epublished ahead of print.
In 26 subjects, movement of the head into the lateral position while the body remained supine resulted in a significant reduction in the apnea hypopnea index (AHI) from a mean of 36 to 26 (p=0.008) compared to when head and body positions were both supine. These results demonstrate an important influence of head position on the AHI independently of body position in OSA patients.
