Abstract

The factors which are important in the design and use of apparatus for the effective displacement of air by carbon dioxide from chest cavities are examined. High levels of carbon dioxide can be achieved by flowing carbon dioxide at a total flow rate of 51./min. into the chest cavity through two nozzles of 0·5 to 1·0 cm. diameter. The effect of factors which might diminish the carbon dioxide levels is examined.

摘要

研究了在设计和使用通过二氧化碳有效置换胸腔内空气的装置时的重要因素。通过以5升/分钟的总流速将二氧化碳通过两个直径为0.5至1.0厘米的喷嘴流入胸腔,可以实现高二氧化碳水平。研究了可能降低二氧化碳水平的因素的影响。
