In a device for the inhalation of medicaments with assisted intermittent positive pressure ventilation for the treatment of patients with reduced or disturbed pulmonary function, the breathing air is enriched with medicaments by means of an atomizer, whose output can be adjusted, and administered to the patient at an adjustable flow rate within adjustable pressure limits. At the same time, the breathing air can be enriched in oxygen having a pre-selectable concentration during the inspiration phase, the oxygen concentration being regulated at a constant rate independently of the chosen flow rate. To this end, the inhalation ventilator according to the invention uses an electronic control unit in which the values measured for the ventilation pressure, flow rate, atomizer output and oxygen concentration are determined, compared with specified values and controlled via adjustment members. |
