How Finger Pulse Oximeter Works
During blood oxygen measurement, the difference between the reduced hemoglobin and the oxygenated hemoglobin by detecting the difference between the two types of light absorption at different wavelengths is the most basic data for measuring blood oxygen saturation. In the blood oxygen test, 660nm and 910nm are the two most common wavelengths. In fact, to achieve higher accuracy, in addition to the two wavelengths, even up to 8 wavelengths must be added. The main reason is that human hemoglobin is not only reduced to hemoglobin and In addition to oxyhemoglobin, there are other hemoglobins. We often see carboxyhemoglobin. More wavelengths will help you to do better.
1. Introduction to finger pulse oximeter
Provide a customized solution for the development of blood oxygen pulse rate detector based on blood oxygen pulse rate module; digital display of measurement results, intelligent reminder of abnormal results; can be connected to the development of medical Internet of Things, and the detection data can be uploaded to the cloud in real time; medical-grade blood oxygen pulse rate detection standard.
2. Overview of finger pulse oximeter
Blood oxygen saturation is the percentage of the capacity of oxygenated hemoglobin (HbO2) in the blood to the total bindable hemoglobin (Hb) capacity, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory and circulatory system. The finger pulse oximeter is small in size, low in power consumption, easy to use and easy to carry. When measuring, simply insert your finger into the finger-clip photoelectric sensor to measure the blood oxygen saturation value.
3. Measurement principle of finger pulse oximeter
The measurement principle of the oximeter is based on the absorption spectral characteristics of reduced hemoglobin (Hb) and oxyhemoglobin (HbO2) in red and near-red light. Its working principle is to use photoelectric blood oxygen detection technology combined with plethysmography technology. Two beams of light with different wavelengths are used to irradiate the human fingertips to obtain measurement signals from photosensitive components. The obtained information is processed and analyzed. Blood oxygen saturation value.
Heart rate variability (HRV) can also be tested with an oximeter. It reflects the irregularity of the heartbeat. If the heartbeat is regular, the HRV will be relatively high; if the heartbeat interval is relatively different, your HRV will be relatively low. This irregularity of the heartbeat is controlled by the autonomic nerves. A lower HRV was associated with a higher risk of anxiety, depression morbidity, and cardiovascular mortality. People with higher HRV generally have better cardiovascular function and stress resistance.
