A Pulse Oximeter is a small electronic device that can estimate the saturation of oxygen in the blood. You want the estimated number to be in the range of 95% to 100%. If the number drops to 92% or lower, you will need medical attention/attention. When it is less than 92%, the doctor will usually supplement you with oxygen and keep you in the hospital for observation.
The term for hypoxia is hypoxemia. In this case, your body organs may not work properly. Severe conditions can interfere with the function of the heart or brain. Pulse oximeters are usually used in certain physical examinations and are considered essential instruments during intensive care. The pulse oximeter can also monitor problems such as arrhythmia.
A novel coronavirus-infected pneumonia epidemic has made everyone aware of the importance of blood oxygen saturation pulse oximeter. It uses infrared light technology to detect the brightness of light after penetrating the skin of the finger to the blood and musculoskeletal tissues, which is safe Accurate and non-invasive, just gently pinch your finger, 3 seconds to calculate the concentration of oxygenated blood in the blood through light absorption, and give health information such as blood oxygen saturation and heartbeats per minute.
The error of the Best Pulse Oximeter is about 2%. Monitoring arterial oxygen saturation (SaO2) can evaluate the oxygenation and hemoglobin carrying capacity of the lungs. Normal oxygen saturation is 95%~98%. Venous blood Is 75%. The oximeter is very small and can be measured by just holding a finger. If the oximeter is used at home, the reading is not less than 90%, which is normal; oxygen is one of the three major elements of life and a key substance in life movement.
Hypoxemia can cause dizziness, weakness, vomiting and other symptoms in patients, while severe cases can be life-threatening; therefore, understanding the blood oxygen saturation of the patient’s body helps doctors find problems in time, which is very important in the field of clinical medicine. The significance of the finger oximeter can accurately help patients measure human blood oxygen saturation. Clinical experiments show that the finger oximeter has high accuracy and repeatability.
Under what circumstances will the blood oxygen saturation change? Most people with new coronavirus-infected pneumonia still have fever, and only a few people may not have a fever. Therefore, it cannot be said that blood oxygen saturation is more judgmental than fever. Besides, most mild patients have fever, but there is no blood oxygen saturation. Changes, changes in blood oxygen saturation will only occur when there are more lung diseases.
According to the Pulse Oximeter Manufacturers, some pulse oximeters are currently equipped with variable pulse tone. The tone of the audible signal will change with the blood oxygen saturation value. Therefore, the tone reduces oxygen saturation. Low blood pressure, low pulse rate and SpO2 alarms, cardiovascular, respiratory diseases, elderly people over 60, athletes, working more than 12 hours a day, long-term alcoholics, once hypoxia occurs, the consequences are serious, use pulse oximeter to test blood oxygen The content will greatly reduce the incidence of respiratory tract and avoid potential accidents.
