[Controlled hyperventilation with dead space (author's transl)].
We report on a new kind of ventilation-hyperventilation, whereby dead space is added between the patient and the respirator. This kind of ventilation is compared with positive end expiratory pressure ventilation together with intermittent sighs on 10 dogs. Over a period of 80 hours no respiratory or circulatory differences were found in the two groups. There also was no difference in clinical or anatomic histologic findings. It was demonstrated that dogs can be artificially ventilated for a much longer period than estimated. The findings of "respirator lungs" were only shown in an emphysema of the lungs.
