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

Accurate oxygen saturation measurement is foundational for modern physiological monitoring, especially for developers of pulse oximeters, wearables, and multiparameter platforms. Yet many devices fail to achieve regulatory expectations because their performance is never tested across the full range of oxygen saturation levels humans experience. Controlled desaturation studies fill this gap, ensuring claims reflect real-world performance. These studies intentionally and safel
