Abstract
For simplifying the measurement of respiratory resistance, an apparatus attached with the digital counter was devised and results were compared with those obtained by the one attached with Braun tube indicator. The following results were obtained. 1. The values obtained by the apparatus attached with digital counter showed greater dispersion than the values obtained by the other, as the values obtained by former showed the immediately after putting on the switch. Therefore mean value were calculated from the results of five times measurement. 2. The correlation of the obtained values from two kind of apparatus was recognized. But the perfect coincidence between them could not be found. 3. As to the measurement by these two apparatuses, it is necessary to determine the measuring coudition that can exactly detect each state of airway disturbance.
