AHI Calculator - Apnea-Hypopnea Index

Your details

Children use lower thresholds because even a few events per hour is considered abnormal in younger sleepers.
Total number of complete breathing cessations during the sleep study. Each apnea lasts at least 10 seconds with airflow reduced below 10% of baseline.
events
Total number of partial airflow obstructions during the sleep study. Each hypopnea involves at least 30% airflow reduction for 10 or more seconds.
events
Actual sleep time recorded during the study - not the time in bed. Home sleep tests that use recording time (not sleep time) may underestimate AHI by about 15%.

Your AHI is 10.0 events/hr - Mild sleep apnea.

  • Mild sleep apnea (AHI 5-14) is often managed with lifestyle changes, positional therapy, or an oral appliance.
  • Common symptoms include snoring, daytime sleepiness, and waking unrefreshed. A follow-up with a sleep physician is recommended.
  • Your study recorded 60 total events over 6.00 hours of sleep, giving 10.0 events per hour.
  • AHI is a screening metric, not a standalone diagnosis. It should always be interpreted alongside oxygen saturation data, symptoms, and clinical context by a qualified sleep physician.

Next stepBring these results to a sleep medicine specialist. A full polysomnography or titration study will determine the right treatment pressure or device for you.
