How much is the pulse oximeter normal

The pulse oximeter is normally between 60 and 100.

The main monitoring indicators of the pulse oximeter are pulse rate and blood oxygen saturation. The pulse can be represented by P2, and the normal value is usually between 60 and 100. Of course, when people are nervous or exercising, the pulse rate will increase. Another indicator is blood oxygen saturation, which is marked by SpO2. Blood oxygen saturation is only the capacity of oxygen and hemoglobin combined by oxygen in the blood, accounting for the percentage of all hemoglobin that can be combined, that is, the concentration of blood oxygen in the blood, and it is an important physiological parameter of respiratory circulation. It is very convenient to detect by finger clip method without trauma. The normal value is 95% to 98%. Of course, some can reach 100%. If it is lower than 95%, it indicates that there is hypoxia. For chronic respiratory diseases, such as COPD, asthma, pulmonary interstitial diseases, and chronic heart disease, hypoxia often occurs. The oximeter can guide the treatment and closely observe the blood oxygen status. It is a very convenient instrument.

The pulse oximeter provides a non-invasive method to measure blood oxygen saturation or arterial heme saturation. The pulse oximeter can also detect arterial pulsation, so it can also calculate and inform the patient's heart rate. The pulse oximeter is a medical device that measures the oxygen content in the patient's arterial blood.

In addition to heart rate, blood pressure, respiratory rate and temperature, pulse oxygen is considered to be the fifth most important health indicator. Hemoglobin is an important component of blood cells and is responsible for transporting oxygen from the lungs to other tissues of the body. The amount of oxygen contained in hemoglobin at any time is called blood oxygen saturation, which is expressed as a percentage, that is, the ratio of the oxygen content of hemoglobin to the oxygen carrying capacity of hemoglobin. Blood oxygen saturation is an important physiological parameter reflecting whether human respiratory function and oxygen content are normal, which is an important physiological parameter, indicating whether human tissues are healthy.
