In this paper, we discuss the development of an easy-to-use non-intrusive endothelial function assessment instrument. The instrument records the digital pulse volume (DPV) from the fingers. We studied 42 subjects (28 men and 14 women, 22 to 64 years of age) and showed the good performance of self-developed system for monitoring endothelial function. The system is capable to apply both area under the...
In this paper, we discuss the development of an easy-to-use non-intrusive arterial stiffness assessment instrument PWV-DVPE (pulse wave velocity by digital volume pulse easy). The instrument records the digital volume pulses simultaneously from both the finger and the ear. The time delay difference between the two digital volume pulses is measured. The PWV is calculated by dividing the difference...
In this paper, we discuss the development of an easy-to-use non-intrusive endothelial function assessment instrument. The instrument records the digital pulse volume (DPV) from the fingers. We studied 31 subjects (22 men and 9 women, 22 to 78 years of age) and showed the good performance of self-developed system for monitoring endothelial function. The system is capable to apply both area under the...
In this study, 41 asymptomatic subjects (22 men and 19 women, 20 to 60 years of age) were enrolled. The PWV was measured both by dual-channel PPG (PWV-DVP) and by the proposed PWV instrument, pulse wave velocity by digital volume pulse easy (PWV-DVPE). The developed system recorded digital volume pulse simultaneously from both the finger and ear. Time of pulse transition was measured on the time delay...
