Accurate oxygen saturation measurement is foundational for modern physiological monitoring, especially for developers of pulse oximeters, wearables, and multiparameter platforms. Yet many devices fail to achieve regulatory expectations because their performance is never tested across the full range of oxygen saturation levels humans experience.  Controlled desaturation studies fill this gap, ensuring claims reflect real-world performance. These studies intentionally and safel

How PRL Ensures Data Integrity in Physiological Monitoring Research   For CTOs and technical leaders in MedTech, data integrity is not a paperwork detail—it is the backbone of regulator-ready evidence. Whether your device requires pulse oximetry testing during controlled desaturation in a hypoxia lab, multi-parameter wearables validation, or multi-site clinical research studies, every data point must be defensible. ALCOA+ provides the industry-standard framework for achieving
