Physiological monitoring in wearables has expanded rapidly, but blood pressure and heart-rate sensing now represent two of the most scrutinized technologies for regulators. As devices transition from lifestyle tools to clinical-grade solutions, development teams must demonstrate performance that meets rigorous standards such as ISO 81060-2 , ISO 81060-7, ISO 81060-3 and ISO 14155 .  Parameters Research Laboratory (PRL) supports developers navigating this shift by delivering

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

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

Blood Pressure Monitoring: A Clinical Cornerstone   Blood pressure measurement is one of the most common clinical assessments, shaping decisions in nearly every healthcare setting. However, not all blood pressure monitors provide the accuracy needed for safe clinical use. FDA-approved devices  stand apart by meeting strict accuracy standards backed by international validation protocols  and clinical research studies .  In the United States, most blood pressure monitors aren’t
