Hypopneas sentence example
The apnea hypopnea index divides the number of hypopneas and apneas into the number of hours the patient sleeps.
For example, if a person sleeps eight hours and experiences 40 apneas and 60 hypopneas, the AHI value is 12.5, which would be a mild case.
The respiratory disturbance index (RDI) is a measurement that includes hypopneas and apneas in its calculations.
Since this measurement includes arousals that are not necessarily hypopneas or apneas, the RDI measurement may be higher than the AHI, according to CPAP Talk.Advertisement
