The main measurement indexes of oximeter are pulse rate, oxygen saturation and perfusion index (PI). Oxygen saturation is one of the important basic data in clinical medicine. Oxygen saturation refers to the percentage of bound O2 capacity in total blood volume to total bound O2 capacity.
The main measurement indexes of oximeter are pulse rate, oxygen saturation and perfusion index (PI).
Pulse rate:
Pulse condition refers to the pulse of superficial artery. The pulse and heartbeat of a normal person are the same.
Heart rate is the rate at which the heart beats. The average person is between 60 and 90 times per minute. However, when people are exercising and nervous, their heart beats faster.
Pulse rate is the number of pulses per minute.
Normally, the pulse rate and heart rate are the same. When atrial fibrillation or frequent premature beats occur, the pulse rate is less than the heart rate.
Oxygen saturation (SO2) is one of the important basic data in clinical medicine.
The oxygen consumed by human body mainly comes from hemoglobin (there are four kinds of hemoglobin in normal blood: oxygenated hemoglobin (HbO2), reduced hemoglobin (Hb), carboxyhemoglobin (CoHb) and methemoglobin (MetHb).
Among them, reduced hemoglobin is reversibly bound to oxygen, while carbohemoglobin and methemoglobin are not bound to oxygen. ) The oxygen it carries. Usually, the oxygen content in blood refers to the amount of oxygenated hemoglobin in blood, and the physical quantity of oxygen saturation is used to describe the change of oxygen content in blood.
