What is the 3% rule for sleep apnea?

The "3% rule" in sleep apnea refers to the diagnostic guideline from the American Academy of Sleep Medicine (AASM) for scoring a hypopnea (a partial breathing blockage) as a significant event if it involves a ≥3% drop in blood oxygen (SpO2) from baseline or is associated with an arousal from sleep, alongside a ≥30% airflow reduction for ≥10 seconds. This contrasts with the older or stricter 4% rule, used by some payers like CMS, requiring a ≥4% oxygen drop, which often misses cases, especially in women or older adults, leading to underdiagnosis compared to the more sensitive 3% rule.
