Definition : Ventilators designed to use positive pressure to deliver a prescribed mixture of respiratory and anesthetic gases and vapors to the patient's lungs during surgical procedures that require general anesthesia; the mixture is produced by the anesthesia unit. Many anesthesia ventilators are time-cycled devices that have only one mode of operation, but some incorporate other modes (e.g., synchronized intermittent mandatory ventilation). Anesthesia ventilators are usually less complex than critical care ventilators. Most anesthesia units include these ventilators either as an integral part or as an optional device.
