what is a ventilator

A ventilator is a machine that helps a person breathe when they cannot breathe well on their own. It can provide oxygen, remove carbon dioxide, and keep the lungs open by supporting the breathing process.

Quick Scoop

In hospitals, ventilators are used for people with severe breathing problems, during surgery, or in critical care when the lungs need extra support. Some ventilators fully take over breathing, while others only assist with each breath.

How it works

• It pushes air, often mixed with oxygen, into the lungs.

• It helps move carbon dioxide out of the body.

• It can maintain pressure so tiny air sacs in the lungs do not collapse.

Simple example

If someone has severe pneumonia or is under general anesthesia, a ventilator may temporarily do part or all of the breathing work until they can breathe more normally again.

TL;DR: A ventilator is a breathing-support machine used when someone’s lungs need help or cannot do the job well enough on their own.
