In addition, the control unit 12 analyzes the measured optical pulse wave in the time domain (Time Domain) or frequency domain (Frequency Domain). Photoelectric pulse wave in the time domain is absorbed by skin, bone, tissue (AC signal), absorbed by venous blood (AC signal), absorbed by pulsating arterial blood (AC signal), absorbed by non-pulsating arterial blood (DC Signal). The ratio of the AC signal to the DC signal is one of the important factors in analyzing the photoelectric pulse wave.

The vascular aging degree is obtained using the values a, b, c, and d.

In addition, the controller 12 may obtain a pulse rate by analyzing a waveform obtained by firstly dividing the measured pulse wave.

The vascular aging degree is obtained by combining the peak values a, b, c, and d of the second derivative waveform of the pulse wave, and is expressed by Equation (2). In addition, the vascular aging degree, the higher the value indicates that the vascular aging degree is good. The degree of aging of blood vessels representing the state of blood vessels, when blood clots accumulate in the blood vessel wall, the passage of blood flow in the blood vessels is relatively reduced, thereby increasing resistance, which is a factor that may affect blood pressure.
