A pneumatically-powered, lightweight device that is easily moved/mounted and used to provide long-term alveolar ventilation support for patients who do not require complex critical care ventilation. It typically uses positive pressure to deliver gas to the lungs at normal breathing rates and tidal volumes through an endotracheal (ET) tube, tracheostomy cannula, or mask. It includes a control system and alarms, sometimes with additional features (e.g., humidification). Several methods of cycling and ventilation modes may be used. It is typically used in the home, but may also be used in an extended care facility, and/or by emergency medical services (EMS).
