AB - Chapter 2 Apparatus This method was based on Krogh’s spironzeter (1922) in order that an apparatus could be devised suitable for the big hospitals in Sweden. Krogh’s apparatus is used in Sweden, and its working principles and the art of managing it are familiar to all. It is built on the principle of the closed system in which the carbon dioxide is absorbed by soda lime and the container for the soda lime is built into the spirometer. Only the oxygen conszdmp- tion is measured and this value is obtained from the decrease in the volume of the system, which is recorded continuously on a kymograph. In addition to the Krogh’s spirometer, a respiration chamber and a circulation pump were needed for the investigations on infants. The respiration chamber (see Fig. 6) was built in two parts. It consists of: (I) a bottom plate made of a folded and soldered metal sheet, with a 15 mm thick heat-isolating cork plate for the child. Round the edge runs a 50 mm high and 25 mm broad trap for water. At the foot of the chamber there is a semi- circular perforated tube for the incoming air and, at the head
