A PAP-NAP is a daytime trial that is usually conducted in a sleep center.
The primary objective of the PAP-NAP is to help patients accommodate to CPAP (continuous positive airway pressure).
Some patients have difficulty tolerating CPAP. In a controlled environment, under the supervision of sleep professionals, a PAPNAP may help some patients to become more comfortable with CPAP. Compliance is a major issue with CPAP treatment.
