KIN 6036 – Clinical Exercise Testing and Interpretation CPEX Reveals Difference between CVD and Lung Disease During a Cardiopulmonary Exercise Test (CPEX) certain indicators of functional capacity can be evaluated to differentiate whether any limitations are because of a heart or lung issue. We can conclude right off the bat that if there is a function problem then we will typically observe a low VO2Max for both lung and heart issues. However, there are several responses and observations during a CPEX that can help us evaluate which is the limiter – heart vs lung. A few of these differentiating variables are listed below. Reason for stopping the test (dyspnea vs leg fatigue) Low or high heart rate reserve Normal or low VE reserve Lower O2 pulse (which one) A decreased VT vs No VT (or RCP) observed To answer this exam question use the variables above to describe what you would likely find in a patient with lung disease versus a person with cardiovascular disease. How would these variables respond. Probably the best way to set-up your answer is with two columns; one for CVD and one for lung disease and then describe how the variables would present on each side. You should also provide some justification for why the variable responds the way it does for each side (e.g., why is VE reserve low, etc.)
