Abstract

[Purpose] We examined a simple method of estimating oxygen consumption of the respiratory muscles (VO2 resp) using dead space. [Subjects] The subjects were 31 healthy adults who had normal cardiopulmonary function. [Methods] We measured VO2 resp of diaphragmatic respiration and costal respiration with simple equipment consisting of an expiration gas analyzer and a one-litre tube. We examined whether decrease of VO2 resp by diaphragmatic respiration could be seen using this equipment. [Results] We confirmed a significant decrease of VO2 resp in diaphragmatic respiration. [Conclusion] The result indicates we can measure changes in VO2 resp by respiration pattern using our simple method.<br>
