A Prominent Increase in Slow Wave Sleep after PAP Therapy

Abstract

Muhammad Riaz and Gaurav Nigam

Sleep disturbances are common in patients with chronic pain syndrome, and coexistent obstructive sleep apnea (OSA) in such patients could further compromise the quality of sleep and increase sleep fragmentation. Here we present an unusual case of profound increase in slow wave sleep as noted during the sleep study and discuss the potential causes for this observed polysomnograhic phenomenon.
