How Ventilators Work: A Beginner’s Guide to Respiratory Support Machines
A ventilator is a medical device that provides mechanical breathing support. It pushes oxygen into the lungs and pulls out carbon dioxide. This helps people with respiratory failure or severe breathing issues.
Ventilators can be invasive or non-invasive. Invasive ventilators use a tube inserted into the windpipe. Non-invasive types use masks over the nose or mouth.
