This AutoVent series integrates field experience and engineering excellence, producing a lightweight, transportable automatic ventilator. Both the AutoVent 2000 and 3000 meet the American Heart Association standards for automatic ventilators. Designed for patients over 44 pounds, both units utilize state-of-the-art pneumatics to assure reliable, time-cycled, constant flow capabilities driven by a minimum of source gas. Independent controls for rate and tidal volume on the AV2000 can be adjusted quickly and monitored at a glance. The AutoVent 2000 and the AutoVent 3000 may be used with standard resuscitation masks or standard endotracheal and tracheostomy tubes.
