What are Respiratory Event Related Arousals (RERAs)?

Sleep Technology Trends | Sleep Technologist Advice


What are Respiratory Event Related arousals?

Respiratory Event Related Arousals (RERAs) are occurrences sleep technologists may see during a patient's sleep study.  Apneas and hypopneas can last anywhere from 10 seconds to over 2 minutes depending on the severity of the patient's condition, and it's important to note that RERAs do not meet the criteria to be called an apnea or hypopnea occurrence, however they do cause arousals.

The role of arousals in sleep is gaining interest among both basic researchers and clinicians.  In the last 20 years increasing evidence showed that arousals are deeply involved in the pathophysiology of sleep disorders.  Sleep disruption results from RERAs.

Differentiating between RERAs and hypopneas can be tricky

Hypopneas and RERAs are often mistaken for one another especially since they both cause disrupted sleep, fatigue and daytime sleepiness among patients who have them.  But patients who have RERAs don't have significant oxygen desaturation.

How sleep technologists can help their patients with disrupted sleep 

Learn how sleep technologists can better monitor sleep studies that involve patients with RERAs.  The AAST offers 1 CEC for the Case of The Month on a patient with respiratory event related arousals who also has hypopnea.  This case discusses recent changes to hypopnea scoring in the AASM scoring manual and the impact on diagnosis of sleep disordered breathing.
