Efficiency of ventilation of Spiromat 650 (Dräger) has been examined in 54 patients under general anaesthesia and relaxation during normoventilation and hyperventilation of 15 and 30% degree. Changes in the acid-base status of arterial blood were used as criteria. There was a tendency to metabolic acidosis in all kinds of ventilation-probably as a consequence of surgical trauma-which was covered by an respiratory alkalosis. In all groups arterial PCO2 was reduced about 25%, without any significant difference between results of normo- 15%-and 20% hyperventilation. Using the Spiromat 650 (Drger) as respirator to normovolemic ventialtion is recommanded for clinical use.
在54例全身麻醉且肌肉松弛的患者中，于正常通气以及15%和30%程度的过度通气状态下，对Spiromat 650（德尔格公司生产）的通气效率进行了检查。以动脉血酸碱状态的变化作为评判标准。在各种通气情况下均有代谢性酸中毒的倾向——这可能是手术创伤的结果——其被呼吸性碱中毒所代偿。在所有组中，动脉血二氧化碳分压均降低了约25%，正常通气、15%过度通气和30%过度通气的结果之间无显著差异。推荐将Spiromat 650（德尔格公司生产）用作正常血容量通气的呼吸机以供临床使用。
