An oximeter is an instrument that monitors blood oxygen saturation. It refers to the degree to which hemoglobin combines with oxygen at a certain partial pressure of oxygen, that is, the percentage of oxygen content and oxygen capacity. Oxygen saturation of the arteries is usually used.
How to look at an oximeter
The main markings on an oximeter are pulse rate, oxygen saturation, and the perfusion index. The first thing to look at is the pulse rate, which is the number of beats per minute. Under normal circumstances, the pulse rate is the same as the heartbeat. In fact, it is also necessary to look at the oxygen saturation level, the normal blood oxygen saturation level is 98 percent, venous blood is usually 75 percent. if the oxygen saturation level is below 94 percent, then it is a sign of insufficient oxygen supply.
How to use the oximeter
1, the first time you use the finger oximeter, first press the Reset button, the LCD screen will display standby status.
2. Then press the start clip port. The middle finger of the left hand or right hand, into the working position, then you can see the infrared light in the working position, should pay attention to: the finger can not be clamped crooked, can not be wet, can not have a foreign body on the surface of the nail.
