Table 5. Differences Between REM-Related and Supine-Related OSA.
| REM-Related OSA | Supine-Related OSA |
|---|---|
| Females | Males |
| Older in age | Younger in age |
| Higher mean BMI | Lower mean BMI |
| Genioglossal hyporesponsiveness | Unfavorable airway geometry due to smaller craniofacial volume (midline obstruction such as thyroid, retroglossal thyroid, or tonsillar enlargement needs to be excluded) |
| Reduced lung volume |
Abbreviations: BMI, body mass index; OSA, obstructive sleep apnea; REM, rapid eye movement.
