Oxyvera develops advanced pulse‑oximetry sensing technology that corrects skin‑tone bias in SpO₂ measurements. By combining broad‑spectrum multi‑wavelength photoplethysmography with clinical colorimeter data, their system characterizes individual skin optical properties, enabling accurate oxygen saturation readings across diverse patients, including those with darker skin.

Problem
Current pulse oximeters produce inaccurate oxygen saturation readings for patients with darker skin because melanin, skin thickness, and hydration alter the optical signal before it reaches the blood. This bias leads to missed or delayed detection of hypoxemia, creating disparities in clinical monitoring and treatment.
Solution
Oxyvera’s technology measures the optical properties of the tissue itself rather than treating skin variability as noise. By combining broad‑spectrum multi‑wavelength photoplethysmography (covering visible to near‑infrared wavelengths) with reference data from clinical colorimeters, the system quantifies melanin concentration, skin thickness, and hydration. These parameters are used to correct the photoplethysmographic signal, enabling accurate SpO₂ calculations for all skin tones. The approach is grounded in peer‑reviewed research and is being validated in ongoing clinical studies, aiming to eliminate skin‑tone bias in pulse oximetry and improve hypoxemia detection across diverse patient populations.
Target Audience
Primary customers are hospitals, intensive care units, and medical device manufacturers that require reliable oxygen saturation monitoring for diverse patient populations.
