0951 NAP-RELATED VARIATION IN SLEEP PROPENSITY AND REM TENDENCY ON THE MSLT: IMPLICATIONS FOR PEDIATRICS

Abstract Introduction: It is often assumed that patients are increasingly unlikely to fall asleep (and have REM) toward the latter naps of a clinical MSLT. However very little data is available on this subject, especially as it relates to pediatrics. This study aims to explore age*nap-related changes in the likelihood of sleep and REM over the course of 5 consecutive naps in a large sample of clinical MSLTs. Methods: Data were extracted from SleepMed’s repository of deidentified PSG and 5 nap MSLTs. Sleep onset was defined as initial sleep latency (ISL) and studies were executed as per AASM guidelines. Studies were excluded if
