Impact of Integrative Cardiopulmonary Exercise Testing (26)
The usefulness of noninvasive measurements in this disorder was further suggested by D’Alonzo et al in ten patients with obliterative pulmonary hypertension. A strong relationship between change in total pulmonary vascular resistance at rest and exercise after nifedipine or diltiazem therapy and increase in maximum exercise Vo2 and oxygen-pulse were demonstrated. They concluded that changes in these variables may be a useful means of following response to treatment in these patients.
When Should Integrative Cardiopulmonary Exercise Testing Be Used?
The integrative cardiopulmonary exercise test can be thought of as having two components. The first is the exercise metabolic stress that amplifies the responses of the organ systems that interact to allow exercise to be performed. The second is the measurement of the gas exchange variables that allow identification of the work capacity of the subject and the organ systems that limit exercise, if any. These two features make the integrative cardiopulmonary exercise test a unique application of physiologic principles to medicine. antibiotic levaquin
Because of improved understanding of the physiology of exercise and the pathophysiology of exercise intolerance, guidelines for exercise testing might be considered to be as follows:

Exertional dyspnea is a common medical complaint.
