Abstract

Point-of-care measurement of blood oxygen saturation is commonly performed using pulse oximetry-based methods, yet clinical evidence indicates that these devices may exhibit racial disparities in accuracy. We are working to develop tissue-mimicking phantoms for performance comparison and standardization of pulse oximeters. In this study, we have evaluated the use of standard silicone modified by reducing curing agent content to reduce material hardness to biologically relevant levels. A new silicone formulation was identified which provides low hardness without modification. Measurements of compliance – channel diameter as a function of fluid pressure – indicate that both materials have potential for use in pulse oximeter testing.
