Why Multi-Site Studies Matter   Physiological monitoring devices increasingly rely on clinical evidence that reflects real-world use and diverse populations. Some studies may require clinical data to be collected across multiple research locations. Multi-site clinical research studies allow sponsors to expand recruitment and collect larger datasets while maintaining consistent study protocols. When executed under Good Clinical Practice (GCP) and ISO 14155, multi-site program

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

Introduction: Verification Defines Trust in Pulse Oximetry Pulse oximeters are among the most widely used physiological monitoring devices—found in hospitals worldwide. Yet, behind every reliable SpO₂ reading lies a complex scientific process: verification against reference standards . Pulse oximeter verification studies (or pivotal studies) confirm how closely a device’s functional oxygen saturation (SpO₂) values align with the true arterial oxygen saturation (SaO₂), measure

When preparing for a regulatory-grade validation study, the temptation is often to move quickly into execution. However, a carefully designed pilot study can reduce risk of costly setbacks such as protocol deviations, recruitment challenges, and misaligned endpoints. Pilot studies act as a proving ground—helping refine study design, anticipate risks, and improve the quality of the data that will ultimately support regulatory submissions.  Defining the Role of a Pilot Study  

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

PRL research staff performing synchronized data collection at multiple sites to ensure consistent, FDA-compliant results. Why Multi-Site Studies Matter for FDA Submissions   Multi-site clinical research studies are often a necessity for medical device and wearable technology developers seeking FDA clearance. They enable broader participant diversity, increase enrollment speed, and strengthen the statistical power of results.  However, multi-site execution introduces complex r
