With the opening of the epidemic, many people have been infected with COVID one after another. Symptoms of infection vary, but in general, they are characterized by fever, sore limbs, sore throat like "swallowing blades", cough, and temporary loss of sense of smell and taste. However, compared with these obvious symptoms, there is a potential symptom that is easily overlooked, and that is hypoxia symptoms. "Silent" hypoxia is the most dangerous, and we need to be more vigilant, especially these types of people need to be paid more attention to.
What is "silent" hypoxia?
"Silent hypoxemia" means that the blood oxygen saturation is lower than the normal level (<93%), but there are no symptoms of dyspnea, such as chest tightness, shortness of breath, wheezing, coughing and expectoration, etc., but the lungs have been damaged , the body tissue has been deprived of oxygen. When infected with the new crown, the upper respiratory symptoms are not serious, the fever is not obvious, and even the hypothermia, but the viral load continues to be positive and turns negative slowly. Because the symptoms were not easy to detect, ground-glass inflammatory changes in both lungs appeared, which was life-threatening.
What are the hazards of hypoxia?
As the blood oxygen concentration decreases, breathing will become shallower and slower, and the symptoms of dyspnea will become more severe. Oxygen cannot meet the needs of various vital organs such as the heart and brain, so insufficient oxygen supply can cause various diseases and even lead to irreversible damage. Sustained and severe hypoxia will cause coma, damage to heart function, heart failure, decreased myocardial contractility, and various arrhythmias may occur in severe cases, and decreased cardiac output will lead to decreased blood pressure. Sustained hypoxemia can cause gastrointestinal ischemia and hypoxia, resulting in damage to gastrointestinal function. Therefore, the early stage of infection mostly presents silent mild symptoms. If the blood oxygen saturation is not monitored systematically, the patient's hypoxemia will be covered by the normal respiratory rate, which will make it difficult to judge the severity of the new coronary pneumonia patients before the hospital. . Early recognition of hypoxaemic conditions in patients is very important. If patients with severe silent hypoxemia are not detected in time, it may delay the best time for patients to see a doctor and treat them, increasing the difficulty of treatment and the mortality rate of patients.
Who needs to pay more attention to "silent hypoxia"?
1. People with vascular-related diseases: such as patients with high blood pressure, diabetes, and cardiovascular and cerebrovascular diseases. Blood cannot circulate normally, which can easily lead to hypoxia.
2. People with respiratory diseases: Respiratory diseases such as chronic obstructive pulmonary disease, cor pulmonale, chronic pneumonia, and pneumoconiosis can cause dyspnea, resulting in hypoxia in the body.
3. Middle-aged and elderly people over 60 years old: With age, cardiopulmonary function and tissue and organ aging, metabolism slows down, resulting in insufficient oxygen supply.
4.Women in pregnant: In the middle and late stages of pregnancy, due to the accelerated growth of the fetus, the intake of oxygen increases. If it is combined with other pregnancy problems such as umbilical cord around the neck, it will cause hypoxia symptoms, which will have a greater impact on the fetus. The phenomenon of hypoxia in pregnant women cannot be ignored .
How to conduct self-protection and monitor "hypoxemia"?
It is difficult to judge "silent" hypoxemia by obvious symptoms, so we need continuous blood oxygen monitoring during COVID-19 infection to determine whether there is "hypoxemia". Nowadays, the medical pressure in hospitals is very high. It is not an ideal way to go to hospitals for special tests. Therefore, it is necessary to prepare blood oxygen instruments that can be monitored at home, such as pulse oxygen monitor. However, the blood oxygen meter does not have real-time blood oxygen monitoring, and can only pick up the instrument to measure the data once, which is very inconvenient for people who want to obtain blood oxygen data at any time.
Smart watch blood oxygen monitoring helps you protect blood oxygen health
Many watches on the market support the blood oxygen monitoring function, such as Apple, Huawei and Garmin watches, which are reliable, but the price will be slightly higher. But today, the editor wants to recommend a watch with high cost performance and reliable health monitoring. Veepoo RIG smart watch is mainly for health monitoring, with the newly upgraded sensor and Veepoo's unique algorithm technology. It supports real-time blood oxygen monitoring. Users can carry out blood oxygen monitoring as long as they raise their wrists, and the monitoring data will be recorded on the APP. Users can easily view their respiratory rate, hypoxia time, heart load, etc., and fully understand their blood oxygen health data. In addition, RIG also supports the nocturnal hypoxia wake-up function. If the blood oxygen saturation at night is abnormal, the watch will give a vibration warning to protect users from falling asleep.
