简要总结
The verification of an investigational pulse oximetry board to verify pulse rate and saturation accuracy over a specified saturation range in diverse populations.
详细描述
To verify the SpO2 and pulse rate accuracy in comparison to a reference standard blood measurements. 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 steadystate 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.
