What Is AHI Sleep Apnea Scale?
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
