MAINTENANCE OF WAKEFULNESS TEST (MWT)

Maintenance of Wakefulness test is typically used to assess the level of daytime alertness. It is used sometimes to determine the effectiveness of therapy for sleep apnea. It is mostly used to determine level of alertness in patients treated for various sleep disorders, typically for commercial driver license certification. An MWT is performed during the day and typically after a CPAP/BIPAP Re-Titration sleep study.
