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

A Persistent Problem Hidden in Plain Sight   For decades, pulse oximetry has served as a cornerstone of clinical monitoring—offering a quick, noninvasive estimate of blood oxygen saturation (SpO₂). Yet, the COVID-19 pandemic exposed a long-standing and underappreciated flaw: pulse oximeters can overestimate oxygen levels in individuals with darker skin pigmentation .  Inaccurate SpO₂ readings may mask hypoxemia , delay treatment decisions, and contribute to existing health di
