A HOLISTIC, INTEGRATED PULSE OXIMETRY SYSTEM
PulSox is a combination of a sock, outsole, wireless pulse oximeter, and mobile app. The sock and outsole have two designated attachment points for securing the pulse oximeter, which uses a colorimeter to accurately adjust data to eliminating racial bias. Blood oxygen levels are wirelessly sent to a mobile app for use by medical professionals, displaying alerts and specific data for each patient.
