A patient needs a ventilator to help them breathe when they cannot breathe normally.
You may need a ventilator when you have a collapsed lung, fluid on the lungs or you have restricted airways and even with the Covid-19 virus some people need to be put on a ventilator especially if they get worse.
But if you do have Covid-19 and need a ventilator then you have a very high chance of dying.
Not everyone who has Covid-19 will need a ventilator but some do.
Ventilator Machines are also used sometimes during surgery to allow the person to breathe when they cannot normally breathe.
When your lungs inhale and exhale air normally, they take in oxygen your cells need to survive and expel carbon dioxide.
The ventilator helps to take the place of the lungs when they cannot normally inhale and exhale the oxygen properly.
A ventilator works to help a person breathe by blowing air into the patients airway through a breathing tube.
On the Ventilator one end of the ventilator tube is inserted into the patient's windpipe and the other end is attached to the ventilator.
The breathing tube of the ventilator machine serves as an airway by letting air and oxygen from the ventilator flows into the lungs.
The ventilator basically acts like an air pump by forcing air that we normally breathe into the persons lungs to help them breathe.
Normally we breathe this same air and oxygen in without any problems but when someone has issues with breathing they need a ventilator.
Being on a ventilator is never a good thing but not everyone on a ventilator will die or be severely ill.
Ventilators are also used sometimes during surgery so that the person can breathe.
