3 general description of the parameters
4 Working principle
COX801VB can continuously measure arterial oxygen saturation without non-invasive. Usually
a sensor is placed in the test site and connected to the COX801VB by cable.
The measurement principle of this product is spectrophotometry.
(1)Differences in the absorption of visible light and infrared light by oxyhemoglobin,
deoxyhemoglobin and plasma.(Such as figure 3)
(2)The amount of arterial blood varies with the pulse, so the amount of light absorbed by
different numbers of arterial blood also changes.
The COX801VB uses a 2-wavelength sensor to distinguish between oxyhemoglobin,
deoxygenated hemoglobin and plasma in the blood. The light of the light-emitting diode of the
COX801VB using the two-wavelength sensor is transmitted to the photodiode through the
measurement site, and the electrical signal obtained by the photodiode through the light
absorption change in the blood pulsation cycle is transmitted to the COX801VB, and the
COX801VB calculates the pulse rate according to the electrical signal returned by the sensor,
Pulse oximetry, perfusion index, plethysmographic wave, bar graph, etc.(Such as figure 4)
3.1 SpO2
The COX801VB continuously measures pulse rate continuously.
3.2 PR
COX801VB can continuously measure the perfusion index without non-invasive.
3.3 PI
COX801VB continuous non-invasive measurement of plethysmographic waves
