ABSTRACT:
A method and apparatus for the controlled simulation of respiratory gas exchange as it takes place in mammals, for the primary purpose of calibrating and checking the performance of laboratory and clinical test equipment systems. The method and apparatus can reproduce any range of respiratory performance by pumping and mixing atmospheric air with a gas mixture of carbon dioxide and nitrogen. This invention provides an accurate, economical and rapid apparatus for on-line calibration of analytical respiratory test systems.
