Description
The biolight pulse oximeter monitor significant vital sign parameters of patients, including spo2 and pulse rate. It senses arterial oxygen saturation physiological change and converses it to electric signal. Then, the data are calculated and analyzed by data analysis software and displayed on screen. The oximeter continuous or spot check monitoring of functional arterial oxygen saturation (spo2) and pulse, and give out alarm when a certain parameter exceeds the default limit. They enable doctors and nurse to know the situation of patients in an accurate and timely manner. The measurement of oxygen saturation of arterial blood (spo2) adopts the principles of light spectra and volume tracing. The led emits lights with two specific wavelengths, which are selectively absorbed by oxyhemoglobin and deoxyhemoglobin. The photodetector measures. The changes in the light intensity after the light passes the capillary network and estimates the ratio of oxyhemoglobin and the total hemoglobin.
