Abbreviated Daytime Sleep Study (e.g. PAP-NAP)


An abbreviated daytime sleep study (PAP NAP) has been explored to address poor compliance and enhance individual comfort and tolerance of CPAP/BiPAP. PAP NAP combines psychological and physiological treatments into one procedure during an abbreviated daytime nap session (100-120 minutes). Sleep technicians employ various coaching and monitoring techniques including mask and pressure desensitization, emotion focused therapy to overcome aversive responses to CPAP, mental imagery to divert the individuals attention from the sensations associated with CPAP and physiological exposure to CPAP.

Obstructive sleep apnea (OSA) or sleep apnea syndrome is a breathing disorder characterized by the cessation of breathing for at least ten seconds, which occurs repetitively throughout the night and is accompanied by hypoxia and hypercapnia.

Overnight polysomnography (PSG) testing is the standard diagnostic test performed for both adult and children. Despite efforts to individualize the treatment, adherence to prescribed therapy (e.g. CPAP, BiPAP) remains tenuous.




Limited data from a single study of PAP-NAP is insufficient evidence to form conclusions on the efficacy of this approach in improving compliance with CPAP. No professional guidelines currently recommend use of PAP NAP as a compliance enhancement for either adults or children.
