Can an ear-worn vital signs monitor accurately measure physiological signals including HR, PEP, SV, CO, and PTT in human subjects?
A novel ear-worn vital signs monitor demonstrates proof-of-concept feasibility for integrated sensing of multiple cardiovascular physiological signals.
He et al. (2015) reported an observational. Ear-worn vital signs monitor was evaluated on Measurement of physiological signals (ECG, BCG, PPG) to obtain vital signs. An ear-worn vital signs monitor successfully measured ECG, BCG, and PPG to estimate heart rate, pre-ejection period, pulse transit time, and cardiac output in 13 subjects.
