Fingertip oximeter control board, fingertip oximeter control board, fingertip pulse oximeter PCBA program development
The main measurement indicators of the oximeter are pulse rate, blood oxygen saturation, and perfusion index (PI). Blood oxygen saturation (oxygen saturation abbreviated as SpO2) is one of the important basic data in clinical medicine. Blood oxygen saturation refers to the percentage of the combined O2 capacity in the total blood volume to the total O2 capacity that can be combined.
Blood oxygen saturation refers to the percentage of the combined O2 capacity in the total blood volume to the total O2 capacity that can be combined. Normal human arterial blood oxygen saturation is 98%, and venous blood is 75%. It is an important indicator that reflects the oxygen status in the body. It is generally believed that the normal value of blood oxygen saturation should not be less than 94%, and it is regarded as insufficient oxygen supply below 94%.
