Transparent clinical operations have become a defining differentiator for high-performing contract research organizations. Yet many medical device and wearable developers still encounter opaque decision-making, limited protocol visibility, and communication gaps that slow execution and create unnecessary regulatory friction. The result is predictable: CRO risk mitigation becomes reactive instead of proactive , and promising technologies reach the FDA or CE mark later than the

The Hidden Measurement Problem Behind COVID-19 Hypoxia   During the height of the COVID-19 pandemic, clinicians encountered a puzzling trend: individuals with dangerously low arterial oxygen levels often appeared clinically stable and comfortable. While “silent” or “happy” hypoxia drew headlines, an equally critical issue— occult hypoxemia —posed a more subtle risk.  Occult hypoxemia  occurs when pulse oximetry readings overestimate true arterial oxygen saturation (SaO₂), mas

The Growing Importance of Precision in Oxygen Monitoring   From hospital wards to fitness wearables, pulse oximeters  have become indispensable tools for noninvasively measuring blood oxygen saturation (SpO₂). Yet the accuracy of these devices, particularly across diverse skin tones and environmental conditions, has come under scrutiny in recent years.  As regulatory bodies and clinical researchers call for more inclusive and transparent validation, the need for a specialized

A Persistent Problem Hidden in Plain Sight   For decades, pulse oximetry has served as a cornerstone of clinical monitoring—offering a quick, noninvasive estimate of blood oxygen saturation (SpO₂). Yet, the COVID-19 pandemic exposed a long-standing and underappreciated flaw: pulse oximeters can overestimate oxygen levels in individuals with darker skin pigmentation .  Inaccurate SpO₂ readings may mask hypoxemia , delay treatment decisions, and contribute to existing health di
