Release date: 2016-01-22 Finger oximeters are now increasingly popular in home medical devices. The finger oximeter is easy to use, and the old man can quickly operate it; the blood oxygen is no longer needed to take blood, and a finger on the finger can know his blood oxygen level and pulse. You can check your health anytime, anywhere at home. Why do you know your blood oxygen level by putting your finger oximeter on your finger? Let us introduce the working principle of the finger oximeter. We all know that the role of hemoglobin is to carry oxygen to various parts of the body. We refer to the oxygen content of hemoglobin at any time as oxygen saturation. This blood oxygen saturation is measured by a finger oximeter. Hemoglobin has a state of carrying oxygen, and of course, there is no-load state. We call oxygen-carrying hemoglobin as oxyhemoglobin, and no-load hemoglobin is called hemoglobin. Oxygenated hemoglobin and reduced hemoglobin have different absorption characteristics in the spectral range of visible light and near infrared. 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 the finger oximeter. After a series of calculations, the finger oximeter displays blood oxygen saturation data on the display. The finger oximeter is not complicated to use. The first time you use the finger oximeter, first press the Reset button and the LED screen will display the ready state. Then press the ejector pin. Insert the left or right middle finger into the work compartment. At this time, you can see the infrared light in the work compartment. Note that the finger can't be pinched, the hand can't be wet, and there can be no foreign objects on the nail surface (such as nail polish). After waiting for the finger to fully contact the work compartment, the LED displays the detection speed. Into the detection state should pay attention to keep the finger under test stable, do not shake up and down, left and right, it is best to put your hand on the table smoothly, breathing evenly adjusted.

• Benefits of Oxygen:
Inhalation of oxygen can improve the level of arterial blood oxygen partial pressure and oxygen
saturation of the body, in addition to promote the metabolism of the body, and is also one of the very
important methods for auxiliary treatment of a variety of diseases. Oxygen inhalation can make the
oxygen in the human tissue more abundant, cells will get sufficient oxygen supply after the
metabolism will be more active, normal people will have a refreshed, memory improved, spirit feeling.
Patients with chronic heart and lung diseases, long-term oxygen inhalation can delay the aggravation
of the disease, at the same time, but also can relieve the symptoms of chest tightness, wheezing and
dyspnea of patients. Especially when working under great pressure, they are prone to dizziness,
