Conventional pulse oximeters based on photoplethysmography (PPG) rely on two-dimensional, point-based optical measurements that are vulnerable to motion artefacts, skin tone interference and poor perfusion. These limitations reduce signal quality and contribute to well-documented bias in real-world use.
Carelight’s Opto Physiological Monitoring (OPM) technology applies a three-dimensional, multispectral optical sensor design that interrogates a volume of tissue, improving vessel interaction and delivering high-quality, multi-wavelength physiological signals across conditions. This volumetric approach increases signal robustness in real-world conditions, supporting consistent physiological monitoring across skin tones, activity levels and clinical environments without reliance on bedside systems.

Dive deeper into the OPM sensor architecture, wavelength specifications, and signal-to-noise metrics.
OPM preserves high-definition pulsatile signals during oxygen desaturation, enabling reliable multi-parameter physiological measurement in real-world and clinically challenging conditions.
