CO2 Measurement

 

Changes in pulmonary blood flow or pulmonary vascular resistance impact exercise tolerance. The change in partial pressure of exhaled carbon dioxide is a direct correlate to pulmonary blood flow and cardiac output. Assessing the pressure of end-tidal CO2 at rest and during exercise gives a clear indication of patient functional status and heart failure severity, and is highly reflective of exercise-induced changes in pulmonary vasculature that may be associated with pulmonary hypertension.
