Recently, all kinds of epidemic prevention supplies
have become a shortage of goods
In addition to antigens and thermometers
finger clip blood oxygen meter has been out of stock
So is there any need to prepare for
?
In this regard, Wang Sheng, director of the Department of Critical Care Medicine of the Tenth People's Hospital Affiliated to Tongji University, said in an interview with a reporter from Shangguan News of the Jiefang Daily -
"In terms of the new coronavirus infection, most families do not need to be equipped with blood oxygen meter."
WHO (WHO) also has an answer to blood oxygen meter in its new coronavirus column, saying that "most people infected with the new coronavirus who receive home care do not need to use pulse oximeters."

If you don’t buy a blood oximeter
Don’t worry, it is not a necessity
Why is the blood oximeter mentioned?
blood oxygen meter is still relatively unfamiliar to many people medical device . Why monitor blood oxygen ? What is the function of a blood oxygen meter?
Wang Sheng introduced that oxygen enters the blood through gas exchange in the respiratory membrane, combines with hemoglobin in the blood, and becomes oxygenated hemoglobin . Blood oxygen saturation is the abbreviation of pulse oxygen saturation, which refers to the percentage of the total hemoglobin in the blood under a certain oxygen partial pressure.
Blood oxygen saturation is widely used in hospitals for monitoring various critical illnesses, reflecting the oxygen supply status of human tissues and organs, and is often used to determine whether the human body has hypoxemia .
The normal value of arterial oxygen saturation in normal people is 95%-100%; if
is less than 90%, it often indicates hypoxemia, and oxygen therapy and other measures are required to be corrected.
The World Health Organization pointed out that people infected with the new coronavirus may experience a drop in blood oxygen, which may be life-threatening. Generally speaking, blood oxygen levels drop below 90%, or a gradual downward trend, may be an early sign that further medical evaluation is needed.
Why do most people
don’t need to prepare a blood oxygen meter?
Generally, only patients who may experience hypoxemia need to monitor blood oxygen saturation, such as patients with severe pneumonia.
abnormal blood oxygen saturation is usually related to lung ventilation dysfunction, lung ventilation dysfunction or significant decrease in oxygen delivery capacity.
That is to say, those who cause cerebral infarction , cerebral hemorrhage or trauma, and those who cause significantly weakening of cough reflexes, senior or central and peripheral neuropathy, respiratory muscle dysfunction, apnea syndrome, bronchial asthma , interstitial pneumonia , chronic obstructive pulmonary disease and emphysema , pulmonary emphysema , etc., have severe impairment of lung ventilation or ventilation function, and have severe heart loss, are prone to hypoxemia. You can consider preparing a finger-clipped blood oxygen meter at home.
For the general population without serious underlying diseases, monitoring blood oxygen saturation is not very meaningful, and there is no need to follow the trend to buy a blood oxygen meter.
If you don’t buy a blood oxygen meter
and are worried about the blood oxygen drop, what should you do?
Wang Sheng said that once chest tightness, shortness of breath, difficulty breathing, or severe asthma after activity, it has a high suggestion that the human body has hypoxemia. Therefore, there is no need to rely on the measurement results of the finger-clipped blood oxygen meter.
He also advised that for those who can move normally, they can make a simple test and judge - let them walk or climb stairs, "People who can walk for more than 200 meters without stopping or go directly to the third floor will usually not have to stay. The cardiopulmonary function is usually not too bad."
After the epidemic prevention policy is optimized
Many citizens feel nervous and even panic
Fear of getting infected with the new coronavirus
Finger-snap blood oxygen meter may be the hot sale of the finger-climbing blood oxygen meter. ml1
also indirectly reflects this tension
In response to this, Wang Sheng said: "From the previous data in Shanghai, excluding the impact of underlying diseases, less than one thousand severely ill patients caused by the new coronavirus infection, and the mortality rate is even lower than that of influenza." He believes that in addition to the elderly with serious underlying diseases or those with severe immunity of and , people with severe immunity of need to pay attention to this, the infection with the new coronavirus does not have much impact on the vast majority of people, so everyone does not need to be overly anxious.We should still be calm and neither look down on us nor panic.
