[A new portable device for ventilatory support (author's transl)].

Transportation of patients requiring continuous ventilatory support and increased inspired oxygen concentrations may be troublesome for the physician and the nursing staff and dangerous for the patients. A new portable ventilator requiring oxygen of three atm. pressure as gas supply was tested for use during in-hospital transportation of more than 300 critically ill patients. Ventilator operation was simple, the machine was resistant to rude handling and the patients were ventilated reliably.
