A mains electricity (AC-powered) automatic cycling device intended to provide long-term alveolar ventilation support for a patient, excluding neonates or small infants, in various clinical uses. It typically uses positive pressure to deliver gas at normal breathing rates and tidal volumes through an endotracheal (ET) tube or tracheostomy, and consists of a breathing circuit, a control system, monitors, and alarms. The inhalation limb includes sites where inspired gas may be heated/humidified, and the exhalation limb includes an exhaust valve to release gas to the ambient air. It can be operated in several modes (e.g., assist/control, synchronized, patient triggered).
