Q:
What Is AHI Sleep Apnea Scale?
A:
The Apnea Hypopnea Index (AHI) refers to the number of times per hour of sleep that your upper airway partially or completely collapses, leading to a brief arousal or awakening from sleep or a drop in blood oxygen levels. And it can be used to classify the severity of sleep apnea.
The AHI sleep apnea scale is classified as follows:
- Normal: AHI < 5 per hour
- Mild sleep apnea: AHI ≥ 5, but < 15 per hour
- Moderate sleep apnea: AHI ≥ 15, but < 30 per hour
- Severe sleep apnea: AHI ≥ 30 per hour
