Web15 de mai. de 2024 · INTRODUCTION. The apnea-hypopnea index (AHI) measures the frequency of potentially significant breathing events and plays a central role in the management of obstructive sleep apnea (OSA). Classically the AHI is compared to cutoffs to determine whether OSA is present and, if present, its level of physiologic severity. Web8 de mai. de 2024 · Important for the diagnosis of OSA, a PSG will measure the apnea/hypopnea index (AHI), which is the average of the apneic and hypopneic episodes per hour of sleep. An AHI score of 1 to 4.9 …
