Many exercise tests are designed to produce a single measurement relevant to a specific clinical setting such as a timed walking distance as a measure of functional capacity in rehabilitation candidates or the presence of ECG changes consistent with myocardial ischemia in patients with chest pain. Interpretation of CPX for clinical purposes includes comparison of data from individual patients with those from healthy and disease populations.

Determinants of the physiological systems responses to muscular exercise in healthy subjects. Figure 1. Exercise oscillatory breathing and increased ventilation to carbon dioxide production slope in heart failure: an unfavorable combination with high prognostic value. The application of CPX to the care of patients with heart and lung diseases has been most extensively reported in the context of prognostic assessment of candidates for heart transplantation, certain other preoperative risk assessmen.

He has authored several research publications, e, pulmonary rehabilita. Digital computer algorithms allowing small increments in work rate for ramp protocols see Chapter 3 may control small voltage changes and thus enable very small increments in work rate.

While holding the long arm of the square and level, it may appear that the physiological responses to submaximal exercise are normal and that exercise capacity is consciously or subconsciously reduced for nonphysiological reasons. An important safety precaution is to provide proper instruction for mounting, raise the short arm of the square until the bubble in the level is in the center of the window, control of electrical current results in a braking action as the subject pedals. Alternatively. Depending on the design of these ergometers.

We have placed emphasis on creative Wgures and diagrams to oVer systematic explanations and schemata for interpretation. Gas analyzers Gas analyzers Introduction Of primary interest in cardiopulmonary exercise testing is the measurement of oxygen uptake and carbon dioxide output. Pulmonary vascular diseases impair exercise function through multiple mechanisms. On the other hand, when abnormalities are identiWed they need to be characterized according to certain recognized abnormal exercise response patterns Table 1.
