Abstract :
A pulmonary function test has been created to measure gas mixing, gas exchange, and flow parameters during tidal volume breathing (TVB) in patients from preschool age to adulthood. This short, effort independent TVB test was made possible by applying a simple lung model, using a multigas analyzer, eliminating valve dead space, dynamically adjusting for flow-gas lag and response time, and correcting for some of the problems of testing children
