AHI, or the apnea-hypopnea index, is a numerical measure that accounts for the number of pauses in your breathing per hour of sleep. 1  These breathing disturbances are typically associated with either a brief arousal or awakening from sleep or a 3 to 4 percent drop in the blood oxygen levels, called a desaturation.
1 An AHI of 30 or more indicates severe sleep apnea. 2  If your machine does not record your AHI, you will have to make adjustments slowly based on what feels better. 3  Making adjustments based on how you feel is, by definition, very subjective.
