B10 Sleep: Zhang Wenhong mentioned the “golden 72 hours”, how can we improve blood oxygen saturation?

Recently, Zhang Wenhong, director of the National Center for Infectious Diseases and director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, expressed his views and suggestions on China's current COVID-19 treatment methods and medical run phenomenon. Yishisleep simply excerpts some core summaries and some popular science knowledge here , hoping to help more family members!

1) Zhang Wenhong: Why was I so anxious? It was because I felt that people were not using the correct treatment plan, and the patients who should have survived did not survive.

2) Zhang Wenhong: As long as your breathing is fine and your oxygen saturation is normal, your case is a mild one!

3) Zhang Wenhong: Remember that for viral infections, giving antibiotics and intravenous drips as soon as a patient comes in is ineffective treatment!!

4) Zhang Wenhong: Antiviral drugs must be used, they must be used! The rational use of hormones must be used. Then oxygen therapy must be in place in each center (*oxygen therapy means using non-invasive ventilators as soon as possible).

5) Zhang Wenhong: Elderly people should take antiviral drugs as soon as possible within 72 hours of onset. This can save lives.

In addition to hospitals, we need to "help ourselves"

What else can we do during the golden 72 hours?

(Four major steps)

After being infected with the new coronavirus, you are short of breath, have chest tightness and shortness of breath, and your blood oxygen saturation is not enough? Can't get into the hospital? Not enough beds, not enough equipment? At this time, we must first maintain normal ventilation. If you have the above symptoms, you can start with a non-invasive ventilator.

The "Shanghai Novel Coronavirus Infection Diagnosis and Treatment Standards and Tiered Diagnosis and Treatment Process" clearly states: "It is necessary to achieve an oxygen saturation of more than 93% as the minimum treatment goal, and adopt non-invasive ventilator support oxygen therapy."

A ventilator is a medical device that can deliver oxygen-containing air into the lungs and expel carbon dioxide-containing gas from the body to help the respiratory system complete ventilation.

Step 1: Wear a ventilator to maintain normal ventilation

Ventilators belong to the category of assisted breathing, which far exceeds the single function of providing oxygen. The principle of non-invasive ventilator treatment is to continuously provide positive pressure ventilation so that oxygen in the air can enter the lungs, fundamentally solving the problem of insufficient blood oxygen saturation caused by inability to breathe normally.

Especially when sleeping at night , you may not be able to breathe normally due to shortness of breath and chest tightness, resulting in repeated hypoxia. At this time, wearing a non-invasive ventilator can prevent the blood oxygen saturation from dropping rapidly.

COVID-19 may cause varying degrees of respiratory distress syndrome and severe infection, and spontaneous breathing is difficult to maintain blood oxygen levels. The use of a ventilator can prevent respiratory and vital organ failure and buy time for other treatments.

Step 2: When chest tightness, shortness of breath and insufficient ventilation

When severe chest tightness and shortness of breath occur, it is important to note that a simple oxygen concentrator may not be able to guarantee oxygen intake due to insufficient ventilation, and a ventilator must be used to increase ventilation and maintain blood oxygen saturation.

Step 3: On the way to the hospital when emergency treatment is needed

When the condition becomes serious, you must seek medical attention immediately. In order to ensure the 72-hour golden time, if conditions permit, you can use a car inverter (applicable to some models) and wear a non-invasive ventilator on the way to the hospital. This can help maintain ventilation and prevent our blood oxygen saturation from dropping rapidly.

Step 4: When waiting in line for treatment at the hospital

Of course, there may be a long waiting time for medical treatment in the hospital. At this time, wearing a non-invasive ventilator and maintaining the body's ventilation can help us make full use of the golden 72 hours and buy time for other medical treatments.

At the same time, hospitals may now have too many emergency patients and insufficient existing ventilators. At this time, wearing a non-invasive ventilator can also maintain the body's ventilation volume well, avoid a rapid drop in blood oxygen saturation, and help cooperate with doctors for active treatment.

The non-invasive sleeping ventilator can improve ventilation and increase our breathing oxygen, which is a must for self-protection and self-rescue. Whether at home, in the car, or in the hospital, the non-invasive ventilator can help us better fight for the golden 72 hours.

In addition to the new crown causing hypoxemia

In fact, in our daily life, we may

Are experiencing symptoms of insufficient blood oxygen saturation?

Some of you may be curious. When I tested it today, the blood oxygen saturation was at a normal level. Why did the "hypoxia" phenomenon occur?

That’s because most of us are in a state of repeated hypoxia, or lack of oxygen, during sleep.

What is blood oxygen saturation?

Blood oxygen saturation (SpO2) is the concentration of blood oxygen in the blood and is an important physiological parameter of respiratory circulation.

Generally speaking, the normal value of blood oxygen saturation is 95%-100%. When the blood oxygen saturation is lower than 90%, respiratory failure may occur.

We may not pay much attention to it in our daily life, but Yishisleep reminds us that once we are in a state of "hypoxia" for a long time, the damage to our body will be all-round. Not only will we be more prone to fatigue, lack of energy, migraine, dizziness and chest tightness, but it will also increase the incidence of various chronic diseases.

Especially at this moment, it will greatly reduce our immunity, making us more vulnerable when facing the virus and more likely to develop serious illness.

How can we improve our blood oxygen saturation in daily life? How can we save our sleep from "lack of oxygen"?

Wearing a sleep apnea machine.

Theoretically, you need to wear a sleep apnea machine whenever you sleep. The sleep apnea machine applies a certain degree of positive airway pressure during the entire exhalation and inhalation process, thereby ensuring the normal ventilation required for our sleep at night. Therefore, it is a qualified and hardworking porter, allowing us to maintain normal blood oxygen saturation, have a truly high-quality sleep, and stay away from sub-health.

*It is important to note here that you should never blindly consume too much pure oxygen!

Excessive oxygen inhalation may also cause respiratory alkalosis, which can have a relatively large impact. It is often mild at first, and then with excessive ventilation, numbness and tingling sensations will appear in the hands, feet, face, and especially around the mouth, followed by chest tightness, chest pain, dizziness, fear, and even convulsions of the limbs, and finally coma with shallow and slow breathing.

The virus continues to spread, and more and more people have come face to face with it, with symptoms ranging from mild to severe.

As a result, there are also some phenomena around us where the disease is delayed or aggravated due to cognitive bias.

Yishi Sleep calls on everyone to pay attention to sleep and respiratory health! Scientific understanding, scientific response, and work together to overcome difficulties.

Yishi Sleep focuses on sleep medicine and services. It has now built an online sleep hospital and laid out an offline chain of Yishi Sleep charging stations.
