the heart rate is the beating times of the heart per minute, and because the heart and the pulse have the consistent beating frequency, the heart rate is estimated by directly measuring according to the waveform of the pulse;
setting N waveforms in t seconds, calculating the heart rate to be F (times/minute),
F＝60N/t。

the pulse blood oxygen adopts the photoelectric technology to measure the blood oxygen saturation according to the Langberger's law;
the transmitted light intensity I and the emitted light intensity I0 have the following relationship:
I＝I 0 e kCd ，
i and I 0 The logarithm of the ratio of (D) is called the optical density D, so the above equation can also be expressed as:
D＝In(I/I 0 )＝kCd，
c is the concentration of blood, D is the path of light through the blood, k is the light absorption coefficient of the blood, and if path D is kept constant, the concentration of blood is proportional to the optical density D;
HbO in blood 2 The absorption coefficient of Hb is far higher than that of HbO in a red light region having a wavelength of 6OO-700nm, unlike that of Hb 2 Is large;
however, in the infrared region of 80O-1000nm, the absorption coefficient of Hb is larger than that of HbO 2 Is small; the absorption point is equal to or near 8O5nm,
the formula for calculating the blood oxygen saturation should be linear, but because of the scattering property of the human body, the square compensation is needed, which can be more accurate,
SaO2＝K 1 R 2 +K 2 R+K 3
k in this formula 1 、K 2 、K 3 Is an empirical constant and R is two photoelectrons over a small time intervalThe ratio of the amplitude variation of the signal, namely:
R＝ΔRED/ΔIR。
