For developers of pulse oximeters, respiratory monitors, and other physiological sensors, validating device performance under reduced oxygen conditions is essential. Hypoxia testing —or controlled desaturation—ensures devices can accurately measure oxygen saturation (SpO₂) across the full range of real-world conditions, from normal oxygen levels to moderate or severe hypoxia.  At Parameters Research Laboratory (PRL), we specialize in conducting regulatory-grade hypoxia studi

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

Sponsors often choose CROs based on price or speed, but the wrong partner can cost far more. Delayed timelines. Poor data. FDA...

Introduction: Why IRB Management Is Critical for Sponsors For sponsors launching clinical trials—especially in fast-moving sectors like wearable medical technology—navigating the Institutional Review Board (IRB) process is often underestimated. Yet IRB approval is a gatekeeper step: no data can be collected, no participant can be enrolled, and no study activity can legally proceed without it. IRB management  involves far more than filing forms. It encompasses preparing ethica
