Fingertip pulse oximeter with TFT screen.
A pulse oximeter is a device for diagnosing the oxygen content in the blood.
The device is worn on a specific part of the body (depending on the type of device), most often - a finger, a wing of a nose or an earlobe.
One of the LEDs emits red light, while the other emits infrared. Since this light effect, depending on the hemoglobin and oxygen in the blood, returns to the pulse oximeter differently, the detector also perceives them differently. The data is processed, and the user receives the finished result on the display in percent. In addition, the device also shows the heart rate, and it can display information both in numerical format and in the form of a graph.
The most compact models are hand held pulse oximeters. They are fixed, as the name suggests, on the finger. With the help of such pulse oximeters, it is possible to measure the oxygen level in the blood of children and adults.
