The main measurement indicators of the oximeter are pulse rate, blood oxygen saturation, and perfusion index (PI). Blood oxygen saturation (oxygen saturation abbreviated as SpO2) is one of the important basic data in clinical medicine. Oxygen saturation refers to the percentage of the combined O2 volume in the total blood volume to the total O2 volume that can be combined.
Main components:
A microprocessor, memory (EPROM and RAM), two digital-to-analog converters that control LEDs, a device that filters and amplifies the signal received by the photodiode, and an analog-to-digital converter that digitizes the received signal to provide the microprocessor . The LED and photodiode are placed in a small probe that is in contact with the patient's fingertip or earlobe. Pulse oximeters generally also include small liquid crystal displays.
Who Needs Pulse Oximeter Most?
1. People with vascular disease (coronary heart disease, high blood pressure, hyperlipidemia, cerebral thrombosis...)
2. People with respiratory diseases (asthma, bronchitis, old chronic bronchitis, pulmonary heart disease, chronic obstructive pulmonary disease...)
3. Seniors over 60
4. People who work more than 12 hours a day
5. Blood oxygen monitoring in extreme sports and high mountain hypoxia environment
6. Long-term alcoholics
