Polysomnography, or sleep study, for obstructive sleep apnea (OSA) should definitely incorporate arousal-based scoring. Here’s why that matters in a nutshell!
The Diagnostic Criteria for OSA
When diagnosing OSA in adults, we rely on the International Classification of Sleep Disorders, which emphasizes the need for an increase in obstructive respiratory events during an attended sleep study or a home sleep apnea test. However, there’s a bit of confusion out there because the scoring criteria for hypopneas aren’t uniform. This inconsistency can lead to differences in lab reports, treatment options, and even insurance policies.
What is Arousal-Based Scoring?
So, what’s the deal with arousal-based scoring? This scoring method takes into account hypopneas that are linked to arousals identified through EEG, whether or not there’s a significant drop in oxygen levels. Arousal-based scoring is crucial because it highlights respiratory events that lead to arousals during sleep, which can cause significant daytime symptoms, even without marked oxygen desaturation.
The Importance of Scoring Arousal-Related Respiratory Events
For patients who might be battling excessive daytime sleepiness, fatigue, or other neurocognitive issues, it’s essential to score these arousal-related respiratory events during polysomnography. The recommended criteria state that hypopneas should be scored when there’s decreased airflow accompanied by either an arousal or a 3% drop in oxygen saturation. If you’re following the acceptable criteria, which requires a 4% drop in oxygen saturation without allowing for arousal-based scoring alone, it’s still important to note any hypopneas per the recommended criteria.
Recommendations for Home Sleep Tests
Given that many home sleep tests lack the ability to detect arousals, we recommend a polysomnography for those at higher risk for OSA, especially if their home test results come back negative. If the results show an apnea-hypopnea index (AHI) of 5 or more, or a respiratory disturbance index (RDI) of 5 or greater, it’s time to consider treatment to help improve quality of life and reduce risks associated with sleep apnea.
