Recently, the problem of "silent hypoxia" in some elderly people after being infected with the new crown has attracted attention, and oximeters have also become a hot commodity
.
.
In the case of oximeter shortage and price increase, some consumers buy smart watches and bracelets with blood oxygen monitoring functions, and even some people monitor blood oxygen
through apps and mini programs.
In this regard, Sha Xianzheng, head of biomedical engineering at China Medical University, said that this monitoring method can play a role in health care reference and exercise guidance, but it is not as accurate
as the blood oxygen saturation meter used in medical specialties.
In addition, oximeters are only monitoring equipment, not treatment equipment, do not blindly rush to buy, stockpile, should let the real need to buy
in time.

The sales of oximeters are tight, and the price increase is obvious
Recently, oximeters have increased in price and out of stock to varying degrees in the market
.
.
Recently, Mr.
Li from Yanqing, Beijing, paid 32 yuan on an e-commerce platform to buy an oximeter, but the product has not been shipped, and the online customer service replied: "We will send it within 24 hours, and if it is not sent within 48 hours, it means that it cannot be sent
.
" A few days later, when he opened the link again, he found that the price of the goods had risen to 126 yuan

On an online complaint platform, Ms.
Zhang of Shanghai said that in the "88 Shopping Festival" event, a certain brand oximeter with an original price of 159 yuan could be purchased after paying 94 yuan, but the price increased to 299 yuan
in December 2022.

On the 3rd, the reporter visited a number of pharmacies in Beijing and found that the selling price of oximeters ranged from
200 yuan to 400 yuan.
The clerk said that different brands and models have different prices, and the store has always been at this price

In order to strengthen supply, the Ministry of Industry and Information Technology recently organized the competent departments and production enterprises of industry and information technology in Beijing, Hebei, Jiangsu, Shenzhen and other places to increase the production and supply of finger clip pulse oximeters, and the daily output increased from 115,000 units in early December to more than
250,000 units.
250,000 units.
Use apps and mini programs to measure blood oxygen? Expert: FYI
While the oximeter was snapped up, some people bought smart watches and bracelets with blood oxygen monitoring functions, and even some people chose to monitor blood oxygen
through apps and mini programs.
through apps and mini programs.
The reporter measured blood oxygen in a small program, put the index finger lightly on the camera and flash of the mobile phone, and measured blood oxygen, heart rate and other indicators in 90 seconds, but the page prompted that the monitoring results are for reference only and cannot be used for medical diagnosis purposes
.
.
Sha Xianzheng analyzed that similar mini programs and mobile apps on the Internet are through mobile phone camera cameras, by measuring the fluctuations and color changes of filling caused by human fingertips or facial arterial blood vessels with heart beats (that is, spectral analysis) to detect indicators such as heart rate and blood oxygen saturation
.
.
Sha Xianzheng said that in general, the principle of measuring blood oxygen saturation and oximeter in mobile phone software is similar, and it is also through the mobile phone camera to measure the absorption and reflection of light of different wavelengths (colors) by the human body, and calculate the degree of
hemoglobin and oxygenated hemoglobin absorption.
Due to the different performance of different mobile phone cameras and the complex use environment, it is difficult to say whether the accuracy of the actual blood oxygen saturation measurement is accurate, but the measurement accuracy of the mobile phone App is certainly not as good as the blood oxygen saturation meter for medical professional use.

In Sha Xianzheng's view, the function of measuring blood oxygen saturation developed by mobile apps can allow users to play a role in health care reference and exercise guidance, and can also alleviate people's anxiety about not being able to purchase oximeters during special periods
.
However, developers should clarify the accuracy and scope of application, and indicate whether it can be used for clinical diagnosis so as not to mislead users

No need to rush to buy and stock up, it should be left to those who really need it
Blood oxygen saturation is one of the important indicators of
good health.
Percutaneous arterial oxygen saturation (hereinafter referred to as "blood oxygen saturation") in normal healthy people should be maintained between 95% and 100%; 90%-94% is insufficient oxygen supply, less than 90% is hypoxia, and less than 80% is severe hypoxia, which will cause greater damage to the body and even endanger life

.
Sha Xianzheng analyzed that under normal circumstances, the human blood oxygen saturation is less than 90%, and the clinical manifestations are chest tightness, shortness of breath, shortness of breath, rapid heart rate, dizziness, general weakness, muscle weakness and other symptoms, and may also appear purple (cyanosis) of lips, fingers, toenails and other symptoms, should be treated as soon as possible through nasal cannula oxygen, high-flow humidified oxygen therapy oxygen inhalation
.
In an emergency, a ventilator is also needed to administer oxygen to avoid injury or even life-threatening
due to lack of oxygen.

Sha Xianzheng introduced that usually low blood oxygen saturation is a slow process, and the body's
hypoxia is gradually aggravated.
The patient's performance is not particularly typical, or the original dyspnea, and suddenly acute exacerbation, the patient feels less obvious, this phenomenon of extremely low blood oxygen saturation but no dyspnea is clinically called "hidden hypoxia"
.
According to the survey, some elderly people over 65 years old, obesity, smoking, chronic obstructive pulmonary disease, diabetes, tumors and other patients are prone to "silent hypoxemia", and the mechanism of occurrence is not fully clear

In Sha Xianzheng's view, in view of the elderly and patients with underlying diseases, they are more likely to have "silent hypoxemia", they are slow to respond to hypoxia, and even do not feel chest tightness and difficulty breathing at all
.
When the disease is severe, they may also have cognitive impairments, and caregivers may have difficulty finding out if they are hypoxic, so they need oxygen saturation monitors to monitor

In the case of tight sales of oximeters, we should not try to find psychological comfort to rush to buy and stock up, which will make people who really need it unable to buy
in time.
