A Study to Measure Cardiovascular Blood Flow During Submaximal Exercise


About this study

The purpose of this study is to determine the ability of the non-invasive Cardiac Profiles (CP) algorithms (based on ECG and pulse oximetry sensors) to measure cardiac blood flow during exercise by assessing how well the CP method works during exercise (movement artifact and noise), how well the CP method tracks our established method, and its sensitivity to small changes in work intensity.
