Impact of Integrative Cardiopulmonary Exercise Testing (30)

Impact of Integrative Cardiopulmonary Exercise Testing (30)Second, there should be agreement on which variables should be interpreted and how much confidence can be placed on decisions made using these variables. Thus, predicted values and their limitations should be discussed. Finally, the advantages and limitations of invasive (arterial catheters and pulmonary artery catheters) studies should be contrasted with the information available from noninvasive testing (eg, gas exchange measurements and pulse oximetry). buy cheap antibiotics
Neuberg has recently raised several other important questions about the current and future use of integrative cardiopulmonary exercise testing, including the implications of results suggesting combinations of pulmonary and cardiovascular diseases, the relationship between exercise-induced symptoms and patterns of gas exchange abnormalities, and the lack of application of decision analysis to these measurements. Consistent methodology and results of prospective studies to answer these questions were suggested as necessary to expand the use of exercise testing. In Table 4, we suggest additional areas that should be addressed to establish further the utility and effectiveness of integrative cardiopulmonary exercise testing in clinical practice. It is likely that consensus conferences highlighting the current state of the art and the areas of current ambiguity in integrative cardiopulmonary exercise testing are needed.
