Device type (GMDN): Transport electric ventilator

An electrically-powered device designed to provide automated, alveolar ventilatory support for patients during interhospital or intrahospital transport, and in emergency situations. It is typically a compact, lightweight, rugged device with internal batteries to power it during patient transport. It typically provides mandatory breaths at pre-set intervals (control mode), not allowing the patient to breathe spontaneously; operation in assist/control and/or synchronized intermittent mandatory ventilation (SIMV) modes is available in some types. It usually includes an airway pressure monitor and low and high pressure alarms; it may be used in ambulances, and in field hospitals.
