Changes in the Lung Function of Asthmatic Children when Tasked with Exercise at High Atmospheric Pressure Using an Atmosphere-Changing Chamber
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.19 Vol.19】
Recently divers who have asthma are increasing along with the increase in the population of divers. The purpose of this study was to evaluate changes of lung function of asthmatic children with exercise at high atmospheric pressure using an atmosphere-changing chamber.
Changing of pressure for 3m under sea-level, asthmatic patients were put in a chamber fixed temperature and humidity. And we measured their lung function after exercise with a cycle ergometer. The other day we used same protocol expect no change of pressure, and measured it. The lung function was a tendency to decrease as atmospheric pressure is high, but this result is not significant because of very few cases. As some reports of asthma and diving were reviewed, asthmatic patient can dive under a very careful guidance of doctor. The environment of safety diving with asthma should be made by investigating the studies from various different aspect.
