title: [Development of a s-IMV-technique for Bird apparatus (author's transl)].
abstract: We have developed our IMV-technique described previously to a s-IMV-technique. The principle of this s-IMV-technique is the following: it is necessary to equip two Bird Mark 7 machines with a special system of tubes. Then, an additional inspiratory volume is exactly given with the inspiration, triggered by the patient. for this purpose we constructed an electronic set which is able to recognize the spontaneous breathing of the patient by means of a thermistor and a bedside monitor. Then, more frequency variable inspiration volumes are applied exactly with the breathing of the patient. The adaptation of this apparatus to the patient is reached by impressing of a red stylus (on the left side of the Bird) by an electromagnet according to the inspiration of the patient. With this method it is possible to vary the treatment of patients with respiratory insufficiency, for instance, controlled artificial respiration, s-IMV up to spontaneous breathing. The F.I.O2 of the inspired gas can be chosen and lies between 9,21 and 1,0. CPAP and PEEP are possible.
