Why ventilator so important in the battle against COVID-19?

   |  July 17, 2020

The COVID-19 has caused shortages of medical devices in many countries, especially ventilators. Many companies around the world planned to produce ventilators. Tesla just reopened the old factory in New York to produce a ventilator also. Why ventilator so important? Why COVID-19 patients need it?

1. What does the COVID-19 virus do to our lungs?

The lung or respiratory system is the main field of the COVID-19 virus attack. A person has two lungs – left and right. The right lung has three leaves, and the left lung has two. The heart is between the two lungs, generally to the left side, occupying a lot of space.

Ventilation is the main function of the lungs. We breathe, exchange oxygen in the air through the lungs into the blood, and expel carbon dioxide from the body. So if the lungs have a problem, we will feel difficult to breathe.

In fact, the early-phase disease may not appear ground-glass opacities (GGO) on CT scans. But as the virus continues to “attack”, the consolidation area of the lung begins to absorb, reducing its density and gradually becoming ground-glass opacity, like a “melted sugar”; with the disease progresses, the inflammation has absorbed, leaving the lung fiber cord focus; and pneumonia deteriorated and then the lungs progressed to the “white lung” stage.

At this time, it will seriously affect the ventilation of the lungs, and continuous oxygen supply is required to ensure the oxygenation of the body. In the worst cases, known as Acute Respiratory Distress Syndrome, if without mechanical ventilation support, the patient will die.


Mechanical ventilation is one of the most effective ways to help people with breathing difficulties.

If a lung infected, some functions will be lost. In order to ensure normal life activities and oxygenation status, mechanical ventilation is needed. As one of the most effective means, mechanical ventilation can effectively:

1. Correction of acute respiratory acidosis

2. Correcting hypoxemia

3. Relieve respiratory muscle fatigue

4. Escort the use of sedatives and muscle relaxants

5. Prevent atelectasis

6, stabilize the chest wall

Mechanical ventilation can only be achieved with the aid of a ventilator.

At present, the number of confirmed cases worldwide has reached a huge figure of 1,000,000+. The daily ventilator reserve of the hospital is far from meeting the needs of patients. So sad to hear news reports that some countries have no choice but to stop using a ventilator for patients over 65 years of age. Such a decision is frustrating but can understand the helplessness. Some countries even initiated animal ventilators for human clinical use. Many companies worldwide plan to switch to ventilators to save more lives!


2. Is a ventilator needed for Vet clinics?

If not because of the epidemic, you may never prepare masks stock, and the hospital may never know the importance to prepare more ventilators as a backup.

There are no reported cases of pets infected COVID-19, but through this epidemic, it is necessary to think about: will animal’s respiratory system get sick? Is a ventilator needed for animal treatment? With more and more people pay attention to medical, will the pet owner select a vet hospital without a ventilator?


The animal’s respiratory system may also get sick

Because of congenital or acquired problems, the animal itself may face problems with ventilation disorder. For example, those short-nosed dogs like the bulldog, appear obvious breathing difficulties even before they get old. If such an animal catches up with the situation where anesthesia is required, it will be even worse!

The ventilator is also needed for animal diagnosis and treatment

Animal reacts differently to certain procedures from what humans do — in that they may not be very cooperative during diagnostic or therapeutic procedures — so anesthesia is administered in a broader range of instances.

Although many vets worry about a higher risk of anesthesia, intolerance to drugs, or ventilator suppression, etc. But as a professional veterinarian or even a professional anesthesiologist, should we think more about how to prevent these potential risks? Clinically proven that the most effective way to deal with the respiratory depression caused by anesthesia is mechanical ventilation. That means you need a ventilator to avoid this risk!

So, think again, it’s time for your vet hospital to equip with a ventilator! To know more information about Animal Ventilator, please don’t hesitate to contact us:


Q1:Which organ does the COVID-19 mainly affect?

The virus mainly invades human lung, leading to respiratory problems.

Q2:Why ventilator so important in the battle against COVID-19?

Without a ventilator, it is difficult for patients to breathe normally. The ventilator is just as important as the face masks in this epidemic situation.

Q3:What functions can a ventilator provide?

Ensure normal ventilation of the body.

Q4:Does the pet disease diagnosis and treatment process need a ventilator to assist ventilation?

Vet clinics also need a ventilator to provide ventilation support. Now Human hospitals are facing the dilemma of ventilator shortage. In fact, vet clinics are now facing the same problem, or even worse.
