What Is a Ventilator?
A ventilator (VEN-til-a-tor) is a machine that supports breathing. These machines mainly are used in hospitals. Ventilators:
- Get oxygen into the lungs.
- Remove carbon dioxide from the body. (Carbon dioxide is a waste gas that can be toxic.)
- Help people breathe easier.
- Breathe for people who have lost all ability to breathe on their own.
A ventilator often is used for short periods, such as during surgery when you're under general anesthesia (AN-es-THE-ze-ah). The term "anesthesia" refers to a loss of feeling and awareness. General anesthesia temporarily puts you to sleep.
The medicines used to induce anesthesia can disrupt normal breathing. A ventilator helps make sure that you continue breathing during surgery.
A ventilator also may be used during treatment for a serious lung disease or other condition that affects normal breathing.
Some people may need to use ventilators long term or for the rest of their lives. In these cases, the machines can be used outside of the hospital—in long-term care facilities or at home.
A ventilator doesn't treat a disease or condition. It's used only for life support.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Ventilator/Ventilator Support, visit www.clinicaltrials.gov.

Benefits of higher oxygen, breathing device persist after infancy
By the time they reached toddlerhood, very preterm infants originally treated with higher oxygen levels continued to show benefits when compared to a group treated with lower oxygen levels, according to a follow-up study by a research network of the National Institutes of Health that confirms earlier network findings, Moreover, infants treated with a respiratory therapy commonly prescribed for adults with obstructive sleep apnea fared as well as those who received the traditional therapy for infant respiratory difficulties, the new study found.
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
