On Friday, Jan. 10, 2020, the AASM released the AASM Manual for the Scoring of Sleep and Associated Events, Version 2.6. Based on the recommendations of the AASM Scoring Manual Committee, the AASM Board of Directors approved several changes in this update to the AASM Scoring Manual. All AASM-accredited sleep facilities are required to implement the new rules in Version 2.6 by July 1, 2020.

The AASM Manual for the Scoring of Sleep and Associated Events is the definitive reference for the evaluation of polysomnography (PSG) and home sleep apnea tests (HSATs). This comprehensive resource provides rules for scoring sleep stages, arousals, respiratory events during sleep, movements during sleep, and cardiac events. The AASM Scoring Manual 2.6 also provides standard montages, electrode placements, and digitization parameters.

Changes in AASM Scoring Manual Version 2.6

Both new and updated rules are included in the AASM Scoring Manual, Version 2.6. These changes address topics such as scoring REM without atonia, electrode placement locations, and events that occur in positive airway pressure (PAP) titrations when a backup rate is used. Read the Summary of Updates in Version 2.6 for a complete list of changes in the new AASM Scoring Manual.
