Ventilator - An Essential Role in COVID-19


What is Ventilator?

Ventilators are generally referred as “life-sustaining” or “life support” equipment.

A machine that provides ventilation (a delivery of consequent breath) mechanically to a person who is unable to breathe or getting insufficiency in breathing by moving air in and out of the lungs.

What is Ventilator?


Ventilators for coronavirus patients:

In the coronavirus pandemic, the placement of ventilators is risky for doctors or medical staff. Due to continuous coughing and splitting, the possibility to transmit the virus is at high rates, therefore special suits covering the whole body of doctor/staff are essential.

How do Ventilators Work?

  • At first, the medical staff (mainly anesthetists) observes the patient and puts him on a procedure called intubation.
  • If the patient enters the worst respiratory conditions or respiratory failures, then he is moved to ICU for ventilation.
  • The patient is made unconscious/sedated. He receives a muscle relaxant where a tube is placed into trachea (windpipe) through mouth or nose as per the conditions of the patient.
  • The tube which is in the trachea is then attached to the ventilator machine.
  • The staff can adjust the push rates of oxygen and air into the lungs. Even the adjustment of oxygen with air can be adjusted by the ventilator.
