Oxygen saturation is the percentage of oxyhemoglobin (HbO2) that is combined with oxygen against all combinable hemogiobin (Hb).
It is an important physiological parameter involved in respiration and circulation.
The oxygen saturation of arterial blood in a normal human body is 98%.
Oxygen saturation is an important indicator of the oxygen condition in the human body.
In general, the normal values of oxygen saturation shall not be lower than 94%.
If the measured value of oxygen saturation is lower than 94%, an insufficient supply of oxygen is considered.
The pulse rate is the number of pulse beats per minute.
Normally, the pulse rate is consistent with the heart rate.
In general, the pulse rate of every people is 60 to 90 beats per minute.
