3.2 Respiratory support: 

3.2.1 Oxygen therapy: Patients with severe symptoms should receive nasal cannulas or masks for oxygen inhalation and timely assessment of respiratory distress and/or hypoxemia should be performed. 

3.2.2 High-flow nasal-catheter oxygenation or noninvasive mechanical ventilation: When respiratory distress and/or hypoxemia of the patient cannot be alleviated after receiving standard oxygen therapy, high-flow nasal cannula oxygen therapy or non-invasive ventilation can be considered. If conditions do not improve or even get worse within a short time (1-2 hours), tracheal intubation and invasive mechanical ventilation should be used in a timely manner.

High-Flow Nasal Cannula (HFNC): 

If oxygen delivered via HFNC is an option for patients with mild hypoxemic respiratory failure:

o Provide masks to be worn over the nasal cannula to reduce the potential for airborne virus transmission. 

o Ensure timely endotracheal intubation and positive pressure mechanical ventilation if the patient’s clinical status deteriorates [3-4].




IV. Why is the oxygen ventilator so important for treating new coronary pneumonia?

According to China’s forensic experts report on their first autopsy of a COVID-19 patient, the virus appears to cause inflammatory reactions in both the deeper part of the airway and the lungs. 


Autopsy Report 

Refer:  https://news.cgtn.com/news/2020-02-28/First-autopsy-results-provide-new-pathology-information-on-COVID-19--OsoAKroq6Q/index.html

First autopsy results provide new pathology information on COVID-19

After being infected, the virus can cause lung damage. The human immune system detects this situation and dilates blood vessels, so that more immune cells can enter, but this will lead to liquid entering the lung. The mucus in the lung will lead to lack of oxygen, making it difficult for the patient to breathe and reducing the oxygen level of the human body.

and the mucus in the lungs can cause insufficient oxygen, make breathing difficult, and reduce the body's oxygen levels.


V. Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia Clinical Classification


To alleviate this, have to use oxygen ventilator to push air with increased oxygen levels into the lungs.

The ventilator also has a humidifier that modifies the heat and moisture in the medical air to match the patient's temperature.

Patients are given medication to relax their breathing muscles so that the machine can fully regulate their breathing.
