Answers
Answer:
The machine helps with two important functions: get more oxygen into the lungs and take carbon dioxide out.
"A ventilator is a fairly fancy piece of technological equipment which is designed to breathe for somebody who is unable to breathe effectively on their own," said David Hill, a pulmonologist who sits on the board of the American Lung Association.
Lungs are interwoven with blood vessels, which is how oxygen gets into the bloodstream and carbon dioxide gets carried out. COVID-19 makes this exchange more difficult in the most severe cases because a patient's lungs are inflamed and filled with fluid. (This also happens with infections like pneumonia).
A ventilator essentially helps a patient's lungs accomplish this task. Modern ventilators consist of a pump machine and a tube that health care professionals slide into your windpipe to control airflow.
