Сòòò½APP’s human testing of pulse oximeters provides real-world data that is not possible with the use of simulators. Turn-key solutions support the development of algorithms and hardware used in pulse oximetry to pulse oximeter validation for regulatory submission. Bringing optimized pulse oximeters to market faster with invaluable physiological and human factor data.
Pulse Oximetry is a noninvasive method for assessment of oxygen saturation levels. Oxygen saturation levels are one of the critical vital signs of life, with normal levels at 92-100%. Pulse oximeters have been widely used in the healthcare industry, helping physicians make informed decisions and monitor overall health. Wearable technologies, such as smart watches and smart devices, are routinely integrating these sensors.
Pulse oximeter clinical validation study overview
Your entire pulse ox clinical validation study will be conducted by Сòòò½APP. Our experienced team will take care of protocol design, IRB submission and management, recruitment and payment of participants, study performance, analysis of data, and for validation studies, assembling high-quality data packages ready for regulatory submission.
The most tested oxygen saturation level is between 70-100%. Oxygen saturation levels are decreased stepwise down to 70% and analyzed at multiple plateaus by a blood co-oximeter. This data is then compared to data being collected by the pulse oximeter device being tested.
SpO2 accuracy performance of the test pulse oximeter will be evaluated in highly controlled conditions over the specified range of oxygen saturation (typically 70-100% SaO2) while being compared to arterial blood samples assessed by CO-Oximetry.
How pulse oximeter clinical validation studies are conducted
A minimum of 15, healthy non-smoking adult participants, ranging in pigmentation from light to dark, are enrolled in each study. This ensures study design requirements will be met, defined by ISO 80601-2-61 and FDA guidance documents.
While participants rest comfortably in a reclined position, an arterial catheter is placed in the radial artery. A gas mixture of medical grade oxygen and nitrogen is administered to participants to induce hypoxia in a series of stair-stepped, stable plateaus down to the minimum target SaO2 level based on the specified range for the test pulse oximeter.
Data is collected from all pulse oximetry systems simultaneously. The oxygen saturation (SpO2) and pulse rate values are automatically recorded via computer from each pulse oximetry system. At each stable plateau, blood samples are drawn during non-motion conditions and immediately analyzed on multiple CO-Oximeters. Want to know more? Get in touch with our team today.
Pulse ox clinical validation study data formatted for regulatory agencies
Upon completion of a clinical validation study for regulatory submission, Сòòò½APP will deliver data in formats that meet or exceed current the requirements outlined in ISO 80601-2-61. Study data is analyzed to derive a statistical comparison between the test device and reference CO-Oximeters. Furthermore, multiple co-oximeters are utilized simultaneously to provide a high degree of accuracy for the reference data. Throughout the regulatory process, our experts will guide and advise you, including during discussions with regulatory bodies, serving as an extension of your team.
