In this vital CE webinar. Dr. Hugh Cassiere, a triple board-certified physician in internal medicine, pulmonology, and critical care, uncovers an often overlooked limitation in patient monitoring: the role of skin pigmentation in pulse oximetry accuracy.
If your global dental practice relies on pulse oximeters for sleep apnea screening, appliance titration, or sedation dentistry, this presentation is essential viewing. Dr. Cassiere explains how pulse oximeters, which use light frequencies to estimate arterial oxygen saturation, are flawed when measuring oxygen in darkly pigmented individuals. Because historical device calibration curves were based on healthy, lightly pigmented subjects, the melanin in darker skin interferes with the red light spectrum (660 nm). This leads to a phenomenon known as “occult hypoxemia,” where a patient’s pulse oximeter might display a safe, normal reading (e.g., 92%-96%) while their actual arterial blood oxygen is critically low.
Key clinical concepts covered in this global webinar include:
