Abstract

The current standard of care for evaluating obstructive sleep apnea (OSA) is polysomnography (PSG), which requires a resource-intensive overnight study and relies on pulse oximetry to determine severity. PSG does not provide direct information about brain oxygenation, but studies have demonstrated that near-infrared spectroscopy (NIRS) technology can be useful in monitoring cerebral hemodynamics. These studies largely rely on commercial bedside tissue oxygenation monitors, although more portable instruments could permit use in home settings. In this work, we evaluate a prototype smartphone compatible NIRS device for assessing OSA, examine hemodynamic responses alongside PSG, and derive two novel metrics for disease severity.
