Pulse oximeters

A pulse oximeter, also known as a blood oxygen meter, is a device that measures a patient's arterial blood pressure (EQS), pulse rate (heart rate, heart rate), and arterial oxygen saturation (SpO2). 

A pulse oximeter is a device that measures the percentage of oxygen in hemoglobin proteins called saturated oxygen. Generally speaking, a pulse oximeter is a device used to measure the amount of oxygen in the blood (SpO2) using photometric methods. Oxygen saturation shows how much oxygen enters the organs. 

It is a portable pulse oximeter for the non-invasive determination of functional oxygen saturation in human arterial blood (SpO2) and the measurement of pulse rate. This device is compact with an integrated finger sensor..

Due to its exceptional mobility and functionality, it can be used in almost any situation where it is necessary to quickly and accurately measure oxygen saturation in the arterial blood and pulse. This can be done at home and in hospitals, during operations, anesthesia, intensive care, pediatrics, physical care and sports centers. Pulse oximetry has become very popular due to its ease of use. Pulse oximeters do not need to be calibrated, they work accurately and reliably. 

Pulse oximetry is based on the absorption of light in tissues (tissue blood vessels), where light is scattered by hemoglobin in both arterial and venous blood, located in the tissues between the light source and the receiver. Direct illumination photodetectors are commonly used. The simulator (finger phantom) consists of light emitting diodes and photodiodes. The photodiodes receive the light emitted by the pulse oximeter LEDs and synchronize the simulator to the pulse oximeter sensor. The LEDs on the pulse oximeter sensor illuminate red and infrared light intensities that correspond to the simulated SpO2.
