A Familiar Framework with Important Regulatory Implications   In January 2026, the FDA released a draft guidance titled “ Cuffless Non-Invasive Blood Pressure Measuring Devices – Clinical Performance Testing and Evaluation .” The document outlines FDA’s current recommendations on how cuffless blood pressure (BP) devices—both intermittent and continuous—should be clinically evaluated to support premarket submissions.  For developers already working in this space, the guidance

Engineering leaders developing physiological monitoring devices often encounter references to “arterial line measurements” in validation standards and technical literature. Although arterial lines are invasive and placed in clinical environments, the data they generate is central to how the industry defines accuracy for non-invasive technologies.  This article explains what an arterial line is, why its measurements are considered a benchmark, and how arterial line data is use

Engineering Reliability: What CTOs Need to Know About Regulatory-Grade Physiological Monitoring Validation   CTOs in medical-device startups face an engineering challenge that extends far beyond hardware and firmware. The success of a physiological monitoring product—whether a pulse oximeter, blood pressure monitor, or wearable sensing platform—depends on rigorous clinical research studies capable of supporting FDA and CE mark submissions. The gap between early engineering va
