Who need monitoring SpO2?
1. People with heart disease, high blood pressure, diabetes, and people with respiratory diseases.
There is lipid deposition in the vascular lumen, and the blood is not smooth, which will lead to difficulty in supplying oxygen.
Using an oximeter can easily check the blood oxygen status of the human body.
The blood is thick, coupled with coronary arteriosclerosis, the vascular lumen is narrowed, and the blood supply is not smooth
and oxygen supply is difficult. The body is "deprived of oxygen" every day. Long-term mild hypoxia, the function of the heart,
brain and other organs that consume a lot of oxygen will gradually decline. Therefore, cardiovascular and cerebrovascular
patients can use pulse oximeter to detect blood oxygen content for a long time, which can effectively prevent the occurrence of
danger.
The blood oxygen detection of patients with respiratory system is indeed very important. On the one hand, breathing difficulties
will lead to insufficient oxygen intake. On the other hand, the persistence of asthma will also block the small branch organs,
making gas exchange difficult, resulting in hypoxia. Causes different degrees of damage to the heart, lungs, brain and even
kidneys. Therefore, using pulse oximeter to detect blood oxygen content can reduce the incidence of respiratory tract.
2.Seniors over 60 years old
The human body relies on blood to transmit oxygen, and if there is less blood, there will naturally be less oxygen. With less
oxygen, the physical condition naturally declines. Therefore, the elderly should use pulse oximetry to detect blood oxygen
content every day. Once blood oxygen is below the warning level, oxygen supplementation is required as soon as possible.
3.People who snore
Snoring is a problem that many people have. In fact, there are many health problems caused by snoring. The decrease
in blood oxygen saturation is related to snoring.
Young people snoring may be due to physical fatigue or sleep posture, but because young people are healthy, even if
they hold their breath for 1-2 minutes, there will be no obvious blood oxygen fluctuations, but once the elderly hold their
breath for 20 seconds, blood may occur. Huge fluctuations in blood oxygen levels.
Monitoring data has shown that if the blood oxygen saturation is lower than 70% during sleep, you must go to the hospital
for treatment. If the blood oxygen concentration in the blood is lower than 65% due to snoring and other reasons, there is
a risk of sudden death at night. . The number of patients with myocardial infarction in the early morning is the most, and
a large part of the reasons are related to snoring.
4.Outdoor sports, mountaineering enthusiasts, sports players
For outdoor/climbing athletes, when the heart rate does not exceed 100 at altitudes above 3000 meters:
• SpO2> 90%: normal
• Between SpO2 80-90%: mild hypoxia. Reduce activity and take adequate rest
• Between SpO2 70-80%: Moderate hypoxia. Appropriate amount of oxygen should be inhaled, and anti-hypoxia drugs
should be taken
• SpO2<70%: Severe hypoxia. Stop all activities and seek medical attention immediately
Long-term SpO2<90% will be in a state of hypoxia, and scholars set SpO2<90% as the standard for hypoxemia.
When SpO2<70%, it is extremely low oxygen saturation, and it is easy to face life-threatening. This is also the reason
why we take out SpO2=70% separately and set it as the life warning line.
5. People who work more than 12 hours a day
Oxygen consumption of the brain accounts for 20% of the oxygen consumption of the whole body, and the oxygen
consumption of the brain is bound to rise due to the transition of mental work. The human body can take in a limited
amount of oxygen, so it consumes more and consumes less. In addition to causing dizziness, fatigue, poor memory,
slow response and other problems, it will also cause serious damage to the brain and myocardium, and even death from
overwork. Therefore, people who study or work 12 hours a day must use pulse oximetry to detect blood oxygen every
day. content, constantly monitor the health of blood oxygen, to ensure the health of the heart and brain.
6. Long-term alcoholics
The human body needs three units of oxygen to completely break down one unit of alcohol. Therefore, hypoxia is one
of the important manifestations of drunkenness. However, long-term alcoholics have developed a certain tolerance
to alcohol and hypoxia, and they are basically undetectable when they are slightly drunk. Such people need to pay
more attention to monitoring blood oxygen changes when drinking.
