SYMPOSIUM PROCEEDINGS I956 The bottleneck in the application of indirect calorimetry is still the need for laborious and skilful gas analysis. I t is this bottleneck that is now under attack in this laboratory. If the attack is successful, the results will be, first a robust oxygen analyser for laboratory use, with a very short response time and small dead space, and later an adaptation of it sufficiently light to be carried by the subject. This in combination with a flow meter will produce an answer directly in terms of oxygen consumption.
