Abstract
Pulse oximetry represents the universal application of optics in modern medicine. However, recent studies have raised concerns regarding the potential impact of confounding factors like variable skin pigmentation and blood content on blood oxygen saturation measurement accuracy. Tissue-mimicking phantom testing offers a low-cost solution for characterizing device performance and potential error sources. Phantom manufacturing literature for pulse oximetry on the human finger was reviewed. Studies were categorized, and relevant optical and mechanical properties were summarized and implemented toward a preliminary phantom for optimal biological relevance using molding and 3D printing. Gaps, recommendations, and strategies were presented for continued phantom development.
