Principle And Use Of OlderFinger Pulse Oximeter

2020/06/12

Now it is more and more popular in household medical devices. The OlderFinger Pulse Oximeter is easy to use, and the old man can quickly operate it himself; blood oxygen measurement no longer requires blood collection. Gently pinch a finger to know his blood oxygen level and pulse. At home, you can check your health anytime, anywhere.

Why do you know your blood oxygen level by putting the Older Finger Pulse Oximeter on your finger? Let's introduce the working principle of OlderFinger Pulse Oximeter.

We all know that the role of hemoglobin is to carry oxygen to all parts of the body. We call the oxygen content of hemoglobin at any time as blood oxygen saturation. Older Finger Pulse Oximeter measures this blood oxygen saturation. Hemoglobin has a state of carrying oxygen, and of course has an empty state. We call the hemoglobin carrying oxygen as oxyhemoglobin, and the empty hemoglobin as reduced hemoglobin.

Oxygenated hemoglobin and reduced hemoglobin have different absorption characteristics in the visible and near infrared spectrum. Reduced hemoglobin absorbs more red frequency light and absorbs less infrared frequency light; while oxyhemoglobin absorbs less red frequency light and absorbs more infrared frequency light. This difference is the most basic basis of OlderFinger Pulse Oximeter.

After a series of calculations, Older Finger Pulse Oximeter displays blood oxygen saturation data on the display.

The use of OlderFinger Pulse Oximeter is not complicated. For the first time to use OlderFinger Pulse Oximeter, first press the Reset button, the screen will show the ready status. Then press the opening jaw. Put your left or right middle finger into the working compartment. At this time, you can see the infrared light in the working compartment. You should pay attention: your fingers should not be crooked, your hands should not be wet, and there should be no foreign objects on the nail surface (such as nail polish). After the finger and the work chamber are fully contacted, the LED displays the detection speed. When entering the detection state, care should be taken to maintain the stability of the finger under test. Do not shake it up, down, left, or right. It is best to place your hand on the table steadily and adjust your breathing evenly.
