Investigation for the dates of polysomnography from obstructive sleep apnea-hypopnea
Obstructive sleep apnea-hypopnea is characterized by repetitive episodes of upper airway obstruction during sleep that disturb sleep architecture and induce intermittent hypoxia [1-5]. OSAH causes daytime hypersomnia and drowsiness, memory loss, and neurocognitive impairment and has been associated with hypertension, cardiovascular diseases, stroke, and diabetes. Laboratory polysomnography (PSG) is considered the “gold standard” for diagnosing and assessing the benefit of a treatment intervention for OSAH, which describes the severity of sleep apnea according to the apnea-hypopnea index (AHI). AHI is a numerical measure that accounts for the number of pauses in breathing per hour of sleep.
