a physIQ digital biomarker brief
A Novel Approach to Estimating Maximum Oxygen Utilization using Wearable Biosensors and Deep Neural Network Technology
An individual’s functional capacity strongly correlates with their quality of life and their risk for future morbidity and mortality. However, current test like the gold standard Cardiopulmonary Exercise Test (CPET) and the less accurate Six-minute Walk Test (6MWT) require in-clinic visits, strenuous exercise, and only capture a point measurement of performance during the test.
physIQ has developed a digital biomarker, eVO2Max, that uses a small wearable biosensor to generate an estimated VO2Max every 24 hours during the testing period which has demonstrated a very high correlation (r=.91) to the CPET-measured VO2Max.
This physIQ Digital Biomarker Brief explains the use of this analytic and how it was developed and validated, a process which was presented in an invited oral abstract during the 2022 Americn Heart Association Scientific Sessions.
