Qubit Systems has developed a range of new analysis systems and associated software that expand the boundaries of CPX testing and pulmonary function measurements. Our breath by breath and mixed expired air systems provide data of unparalleled accuracy that are easy to obtain in a laboratory/indoor environment. They are clearly presented and delivered by software with an enormous range of analytical and reporting capabilities. Our mobile Q-Track CPX system allows measurements in the filed under variable environmental conditions. We have instruments for an experienced sports medicine professional or a novice teacher who wishes to introduce the concepts of CPX testing to students.
