A ventilator (VEN-til-a-tor) is a machine that supports breathing. These machines mainly are used in hospitals. Ventilators:
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.

Restricting calories early on does not help acute lung injury patients on ventilators
Acute lung injury patients on ventilators who require a feeding tube have a similar number of ventilator-free hospital days and similar mortality rates if they receive a low-calorie feeding program initially followed by a full-calorie program compared to a full-calorie program right away.
