OM2 Motion Verification Study

To verify the SpO2 and pulse rate accuracy in comparison to reference-standard blood measurements during motion and non-motion conditions. To achieve paired observations of SpO2 and SaO2 values over the specified SpO2 accuracy range of the prototype pulse oximeter on a group of healthy adult volunteers. The fraction of inspired oxygen (FiO2) delivered to test subjects is varied to achieve a series of targeted steady-state saturation periods. In this study, the investigational pulse oximetry PCBA system saturation measurements will be compared to saturation measurements made by a multi-wavelength CO-oximeter, taken from arterial blood samples from a diverse pool of healthy human subjects.
