The Fingerclip pulse oximeter measures the blood oxygen saturation and pulse rate of the human body through fingers. The advanced DSP algorithms can reduce the influence of motion artifacts and improve measurement accuracy under weak perfusion conditions. The product is suitable for families, hospitals (including internal medicine and surgery, anesthesiology, pediatrics, intensive care, etc.), oxygen bars, community medical care, sports health care, etc. The finger clip pulse oximeter is small in size, low in power consumption, easy to use, and easy to carry. We can insert the finger into the finger spo2sensor to measure the blood oxygen saturation value.
The usage of a finger pulse oximeter is as follows:
- Load two AAA batteries according to the correct standard in the battery compartment and close the battery cover;
- Clamp your fingers into the rubber channel with the fingers fully extended and then loosen the clamp;
- The switch button on the front panel of the stand-alone machine is enough;
- Read relevant data directly from the display screen, which can display blood oxygen saturation, pulse frequency, and pulse amplitude;
- Each time you press the key during the measurement process, you can switch the display direction once. There are four directions for the switch. Or there is a built-in gravity sensor for the direction switch automatically.
What does the Finger oximeter measure?
1. Blood oxygen saturation: Normal human arterial blood oxygen saturation is 98%, and venous blood is 75%. It is an important indicator that reflects the oxygen status in the body. Generally speaking, the standard value of blood oxygen saturation should not be less than 94%, and it is insufficient oxygen supply below 94%.
2. Pulse rate: Pulse refers to the pulsation of superficial arteries. The pulse and heartbeat of a healthy person are the same. Heart rate is how often the heartbeats. The average person is between 60-120 times per minute. However, people may experience rapid heartbeat under conditions such as exercise and tension. Pulse rate is the number of pulses per minute. Under normal circumstances, the pulse rate and the heart rate are the same. When atrial fibrillation or frequent pre-period contractions, the pulse rate is lower than the heart rate.
3. Perfusion Index (PI): The PI value reflects the pulsating blood flow that reflects the blood perfusion ability -- the greater the pulsating blood flow, the greater the pulsating component and the greater the PI value. Therefore, the measurement site (skin, nails, bones, etc.) and the blood perfusion (arterial blood flow) will affect the PI value. Since sympathetic nerves affect heart rate and arterial blood pressure (influencing pulse arterial blood flow), the human body’s neuromodulation system or mental state will indirectly affect the PI value. Therefore, under different anesthesia states, we can get different PIs.
4. Evaluation of test results: According
to medical analysis, the blood oxygen content is higher than or equal to 95. It
is a standard indicator. It is a healthy level when the pulse rate is between
60-100 beats per minute. If the data are not in the range, it is better to test 2-3 times at different
time points and keep the continuous testing for 2-3 days. If the values still do not meet the standards, we have to go to the hospital for
a detailed consultation.
