The main function of oximeter is to monitor blood oxygen saturation, pulse rate and perfusion index, understand the blood oxygen content of patients and guide the treatment of patients.
The oximeter is one of the necessary detection instruments in clinical departments, which has very important clinical value. It can be used to monitor pulse rate, blood oxygen saturation, perfusion index and other basic vital signs, and provide certain reference value for doctors to diagnose and treat diseases.
Pulse rate monitoring: the pulse rate of normal people is 60 ~ 100 beats/min, and it is abnormal that the pulse rate is too fast or too slow; Monitoring of blood oxygen saturation: The blood oxygen saturation of normal people is generally above 95%. When the blood oxygen saturation is too low, it often means that the patient is hypoxic; Monitoring perfusion index: The higher the index, the stronger the perfusion ability of blood flow.
The oximeter belongs to the commonly used personal or hospital medical equipment. Prices range from 100-300.
To sum up, it is normal to buy medical devices for personal use to help others buy oximeters. Not illegal.
