Validation Study of Respiratory Rate Measurement Using Philips FAST Pulse Oximetry Technology in Adults and Children

What this Trial Is About

Researchers are evaluating the accuracy and performance of a new method to measure respiratory rate derived from the plethysmography waveform using Philips FAST Pulse Oximetry technology. This observational study includes adult and pediatric inpatients who are breathing room air and undergoing routine spot-check vital sign monitoring. The goal is to compare respiratory rates obtained from this new noninvasive method with those measured by capnography, a reference standard, to see how well the new algorithm performs without affecting patient care. Participants will undergo noninvasive physiological monitoring during a single study visit using age- and weight-appropriate Philips SpO2 sensors finger, nasal alar, ear along with capnography sensors. Adults will complete two separate 20-minute recording cycles with different sensor combinations, while pediatric participants will complete one or two 20-minute cycles depending on age and weight. Capnography data will be collected simultaneously to serve as the reference for respiratory rate. During the study visit, waveform data will be annotated by clinicians to identify normal breathing and exclude artifacts. Researchers will measure respiratory rate accuracy using metrics such as Accuracy Root Mean Square ARMS, mean bias, and precision during continuous and spot-check monitoring. They will also assess the time to first valid respiratory rate value and adult participant satisfaction with the CO2 cannula. All data collection occurs in a single visit, and no device outputs will be used for clinical decisions.
