Silent hypoxemia, also known as silent hypoxemia, is generally characterized by lower than normal oxygen saturation (
Recently, you will find that people around you have gradually established "little sheep people" with different symptoms. Some people are full of energy after two days of fever, some people have not had a fever for more than a week, and some people have no obvious symptoms. ...
For asymptomatic "Pleasant Goat", it seems lucky. After all, the pain borne by the body is relatively much lighter, but at this time, we must not take it lightly!
No matter what kind of "sheep" you are, various real cases show that Omicron is not a simple "cold".
The milder the symptoms, the more you should be alert to these COVID-19 complications! Such as asymptomatic hypoxemia and viral myocarditis.
Asymptomatic means nothing. Elderly patients should pay attention to ...
Recently, Zhang Wenhong, director of infectious diseases department of Huashan Hospital affiliated to Fudan University, pointed out that some elderly patients were slow to respond to hypoxia, and even did not feel chest tightness, dizziness and dyspnea, so it was too late to be sent to the hospital for treatment.
Because of the weak resistance of the elderly, when they are infected with COVID-19 virus, they have no obvious symptoms, no fever or cough, and often their families think it's all right.
When the virus invades the lungs, it will cause a rapid decline in respiratory ability. Although the elderly can't feel obvious symptoms, at this time, the blood oxygen content is already declining, and the elderly will have drowsiness, easy wrestling, confusion and other phenomena, which is a precursor to respiratory failure!
Therefore, when the elderly are infected with COVID-19 virus, we must be alert to the complications after infection-silent hypoxemia!
Borg rating scale
Ps: If it is not found in time and sent to hospital for treatment, it will develop into acute respiratory distress syndrome, which is life-threatening.
Especially the elderly over 60 years old, patients with basic diseases such as hypertension, diabetes and heart disease. , should pay special attention to. If the fever is not obvious, or even the body chills, and turns positive for many days, you should go to the hospital for treatment in time.
How to judge silent hypoxemia?
The patient's oxygen saturation should be measured in a calm state.
When necessary, the elderly can be allowed to exercise properly before measurement. If the old man still lacks oxygen after walking a little, then it is necessary to consider whether there is silent hypoxemia.
Tips:
After wearing this oximeter, the numbers have been jumping, which may be inaccurate. What should I do?
In engineering, the solution to this problem is simple, rude and effective: add another one.
Prepare two different models/manufacturers of oximeter.
If both machines detect hypoxemia at the same time, send it to the hospital immediately!
Only one has detected hypoxemia, wait two minutes, and if the data of this one still doesn't come back, send it to the hospital at once!
Finally, don't worry too much.
Many experts pointed out that Omicron was infected.
99% can fully recover within 7- 10 days.
Therefore, do a good job in personal protection and vaccination.
Note: asymptomatic infected people do not need to take medicine or abuse antibiotics. Just prepare the medicine properly. There is no need to snap up or hoard.
Plan the quarantine period in advance, don't panic ~
Bye bye ~
