In the hot summer, the temperature jumped straight up. At noon, I couldn’t stand the heat even more. Not to mention working outside, even if I turned on the air conditioner indoors, I felt irritable, and I felt chest tightness and shortness of breath.
Why is chest tightness and shortness of breath in hot weather?
As the temperature rises gradually, the oxygen content in the air decreases, and the human body can obtain less oxygen. When in a mild hypoxia state, it will cause chest tightness, shortness of breath and other symptoms, and severe hypoxia will also cause damage to the brain and myocardium. When the weather is hot, it is recommended to monitor the blood oxygen saturation regularly to master the oxygen supply of the body.
Reminder: In plain areas, under normal oxygen conditions, the blood oxygen saturation of adults should not be less than 95%; in plateau areas, the blood oxygen saturation of adults should not be less than 85% to 90% (depending on altitude).

Who Needs Pulse Oximeter?
As an important indicator for measuring life and health, blood oxygen should be given the same attention as blood glucose, electrocardiogram and other parameters. The following people should pay particular attention to the monitoring of blood oxygen saturation:
People with respiratory diseases (asthma, bronchitis, chronic bronchitis, pulmonary heart disease, etc.)
People suffering from asthma, bronchitis, chronic bronchitis, pulmonary heart disease, etc., on the one hand, breathing difficulties can lead to insufficient oxygen uptake, on the other hand, the persistence of asthma can also block the small organs and make gas exchange difficult, resulting in Hypoxia occurs, causing varying degrees of damage to the heart, lungs, brain and even kidneys.
Seniors over 60
The physiological ageing of the heart and lung organs of the elderly and the deterioration of the blood oxygen circulatory system are likely to cause insufficient oxygen supply. Once the blood oxygen drops below the warning level, it will cause damage to the heart, lung, brain and other organs. Therefore, the elderly should pay more attention to real-time monitoring of blood oxygen saturation.
People who work too long a day
Office people who have been in a state of high pressure for a long time or working overtime have excessive mental work and insufficient oxygen supply to the brain. In addition to causing dizziness, fatigue, poor memory, slow response and other problems, it can also cause serious damage to the brain and myocardium, and even death from overwork. Monitoring blood oxygen saturation can be used for early screening of related diseases that have no symptoms or mild symptoms.
Sports and fitness crowd
Real-time blood oxygen monitoring of athletes helps to understand the blood circulation of athletes after a large amount of exercise, so as to guide the formulation of athletes’ exercise volume.
For people such as plateau travelers and resident reporters, the blood oxygen monitoring can detect the problem of blood carrying or supplying oxygen in advance, and avoid the harm to the body caused by altitude sickness caused by cyanosis.
