What Is ISO 81060-2? ISO 81060-2 is an international standard that defines how to clinically validate intermittent automated non-invasive blood pressure devices. It establishes the study framework used to determine whether a device’s systolic and diastolic readings align with qualified reference measurements under standardized conditions. Key Components of the Standard Validation studies conducted under ISO 81060-2 typically include: Structured measurement sequences using

Why Reference Measurements Matter Every blood pressure validation study relies on a reliable reference method to evaluate device accuracy. A trusted reference measurement provides the foundation for determining whether a monitoring device delivers accurate and clinically meaningful readings. At Parameters Research Laboratory (PRL), reference measurements are conducted by highly trained clinical research staff with deep experience in physiological monitoring studies. This lev

Blood Pressure Device Validation Studies Accurate blood pressure measurement is fundamental to physiological monitoring. As new technologies expand beyond traditional cuffs into wearable and cuffless blood pressure devices, sponsors must demonstrate performance using a structured blood pressure validation study. These studies evaluate how closely a device’s measurements align with reference measurements obtained through established clinical methods and generate the evidence r

What Is Hypoxia and Why It Matters in Device Validation Hypoxia refers to a reduction in oxygen availability at the tissue level. In clinical research and pulse oximetry validation, the focus is arterial oxygen saturation (SaO₂) or the percentage of hemoglobin molecules carrying oxygen in the blood. The Parameters Research Laboratory (PRL) Hypoxia Lab in Broomfield, Colorado is designed for pulse oximetry validation. By safely simulating altitude and lowering oxygen levels

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

A Familiar Framework with Important Regulatory Implications In January 2026, the FDA released a draft guidance titled “ Cuffless Non-Invasive Blood Pressure Measuring Devices – Clinical Performance Testing and Evaluation .”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

Why ISO 81060-2 Matters for Accurate Blood Pressure Monitoring Non-invasive blood pressure devices must demonstrate dependable performance before developers can advance toward FDA or CE mark submissions. ISO 81060-2 “Non-invasive sphygmomanometers — Part 2: Clinical investigation of intermittent automated measurement type ” sets a clear bar for clinical validation—defining study methods, reference comparisons, subject distribution, cuff/arm-size coverage, and prespecified

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

Introduction: The Importance of Clarity in Blood Pressure Device and Software Classification As wearable technology advances, more devices are integrating blood pressure features—from clinical-grade monitors to smartwatches that “notify” users of potential changes. But not all blood pressure devices are created—or regulated—the same. Understanding the difference between a blood pressure measurement device (FDA product code DXN) and a hypertension machine learning-based no

Why Verification Matters in BP Devices Blood pressure (BP) measurement is a foundation of cardiovascular care. But not all BP devices are created equal — increasingly, clinicians and patients recognize that a blood pressure reading is only useful if it’s accurate. To address market confusion around which BP monitors are reliable, the American Medical Association (AMA) introduced the Validated Device Listing (VDL) . The VDL is a free resource that helps clinicians, health

On September 16, 2025, the FDA issued a safety communication warning consumers and healthcare providers about the risks of using unauthorized devices that claim to blood pressure, including certain smartwatch and smart ring features. The agency emphasized that devices without FDA marketing authorization have not been evaluated for safety or effectiveness—leaving users vulnerable to inaccurate readings and potentially harmful health decisions. While this warning highlights t

A recent JAMA survey revealed that many U.S. adults lack key knowledge about hypertension, including the correct threshold for diagnosis and the importance of regular monitoring. Despite widespread awareness of prevention strategies such as diet and exercise, fewer than one-quarter of people with hypertension reported checking their blood pressure more than once a week. This knowledge-behavior gap underscores the need for better tools to support both awareness and action. K

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

Why Arterial Line Monitoring Matters in Research When evaluating new medical devices—particularly those designed for physiological monitoring , such as blood pressure devices or pulse oximeters, researchers need an accurate reference standard. In many cases, arterial line monitoring serves as that standard. By providing continuous, beat-to-beat measurement of arterial blood pressure, arterial lines offer unparalleled accuracy compared to noninvasive methods. This makes the

When it comes to blood pressure validation studies , accuracy is not optional—it’s the foundation. At Parameters Research Laboratory ...

The evolution of blood pressure monitoring is entering a new era—one where cuffs may no longer be required. Cuffless blood pressure devices, powered by optical sensors, photoplethysmography (PPG), and artificial intelligence, promise continuous, comfortable, and non-invasive monitoring. Yet these innovations bring steep challenges, especially when it comes to validating accuracy for clinical and regulatory approval. At Parameters Research Laboratory (PRL), we specialize in
