According to the World Health Organization, one out of every 6 people whose condition worsens due to the emerging corona virus "Covid-19" can suffer from severe difficulty breathing, so artificial respirators formed a haven to save lives to help the patient who cannot breathe at all or partially.
In the case of those infected with Coronavirus, the artificial respirator does not treat the virus, but it allows the patient whose respiratory capacity has decreased to remain alive, until he recovers.
There are two types that differ in the degree of need for them, which are ventilation masks, which are used to pump oxygen to the lungs in cases of simple symptoms of Corona, and the laryngeal tube that is connected to the trachea and is usually used with advanced cases of Corona.
Many reports from Britain, Belgium and others converge on the condition that the oxygen level of a patient suffering from complications of hypoxemia and treatment with oxygen is not less than 92%, regardless of the stage of infection.
Doctors recommend a target of between 92% and 94% to help maintain hospital oxygen supplies.
Studies of oxygen supply cases are classified according to the degree of infection with Covid-19, with the requirement beginning at the lowest of about 3 liters of oxygen per minute.
This percentage increases in cases to about 15 liters of oxygen per minute and exceeds that in advanced cases of "Covid-19", reaching more than 30 liters per minute.
A brief interruption of oxygen - especially for critical cases that depend entirely on respirators - leads to a doubling of the risk of death, especially when the oxygen supply per minute is large.

What is the nature of the artificial respirator?
A ventilator is a machine that provides mechanical ventilation by transferring oxygenated air to the lungs, to assist a patient who cannot breathe on his own or is not sufficiently supplied with oxygen.
Ventilators can save a patient’s life when a person cannot breathe properly or when they cannot breathe on their own at all.
Is artificial respirator used for the purpose of treatment?
The artificial respirator is not a treatment for a disease, but it is used during treatment to stabilize the patient's condition, for example in the case of patients with Corona virus, the artificial respirator does not treat the virus, but it allows the patient whose respiratory ability to survive has decreased, pending his body recovering from the virus and defeating it, or While drug treatments work.
What are the uses of a respirator?
There are many uses, combined with the fact that a person is unable to breathe on their own or cannot breathe adequately, such as:
While recovering from severe cases of the emerging corona virus "Covid-19", when there is a significant decline in the function of the respiratory system.
During surgery when a person is under general anesthesia.
After surgery and while recovering from it, sometimes the patient needs a breathing machine to help him breathe for hours or even days after surgery.
During loss of consciousness.
Coma.
Brain injuries.
Chronic obstructive pulmonary.
Lung infection.
Pneumonia.
brain attack.
Injuries to the upper spinal cord.
How does an artificial device work?
The artificial respirator introduces oxygen into the lungs and expels carbon dioxide, and this includes the use of a tube that connects the ventilator to the airways of the lung through the mouth or nose, and this is called "intubation".
In some severe or long-term cases, the breathing tube is connected directly to the windpipe through a small surgical hole in the neck.
The artificial respirator uses pressure to push the oxidized air into the lungs, and the ventilator needs electricity to operate, and some types can work on the battery.
Although a ventilator can save a person's life, it increases the risk of lung infection, as the breathing tube can allow germs to enter the lungs.
Why do some Corona patients need a ventilator?
In order to answer this question, we must explain what Corona does to the lungs, as the virus attacks two specific groups of cells in the lungs, which are goblet cells and ciliated cells.
The goblet cells produce mucus, which forms a lubricating layer on the respiratory tract, and this is important to help keep the lungs moist, and thus maintain health.
As for ciliary cells, they are cells that have hairs that point upward, and their function is to sweep any harmful substance stuck in the mucus, such as bacteria, viruses, and dust particles, towards the throat to get rid of them.
The Corona virus infects these two groups of cells and begins to kill them, and their tissues begin to fall and collect in the lungs, and the lungs become obstructed, which means that the patient develops pneumonia.
Also, there is another problem, which is that the body's immune system tries to respond because it realizes that the body is under attack, and this may lead to an overabundance of immunity, and then the immune system launches a major attack that damages the healthy tissues in the lung, and this also may make breathing more difficult.
As the ability to breathe decreases, the patient needs a ventilator, otherwise he may not be able to survive.
