Cerebral oxygenation responses to obstructive sleep apnea in cognitively normal older adults: a study using simultaneous polysomnography and functional near-infrared spectroscopy

Scientific Reports
Obstructive sleep apnea (OSA) can cause intermittent cerebral hypoxia that may impair brain health. However, widely used clinical indicators such as the Apnea-Hypopnea Index (AHI) and peripheral oxygen saturation (SpO₂) may not accurately capture ...

Apnea-hypopnea index estimation with wrist-worn photoplethysmography

Abstract Objective Long term monitoring of obstructive sleep apnea (OSA) severity may be relevant for several clinical applications. We developed a method for estimating the apnea-hypopnea index (AHI) using wrist-worn, reflective photoplethysmography (PPG).
