Study Notes
Cardiopulmonary Exercise Testing (CPX)
- A diagnostic and prognostic tool for evaluating cardiovascular, pulmonary, and muscular functions during physical exercise.
- Essential for determining the functional capacity and limitations of an individual's cardiovascular and respiratory systems.
Peak VO2
- Represents the maximal oxygen uptake achieved during exercise testing.
- Serves as the gold standard for assessing aerobic fitness levels and endurance.
Ventilatory Threshold (VT)
- Indicates the exercise intensity level at which ventilation begins to increase disproportionately to oxygen uptake.
- Provides insight into the efficiency of ventilatory processes and aerobic metabolism.
Respiratory Exchange Ratio (RER)
- Calculated as the ratio of carbon dioxide output (VCO2) to oxygen uptake (VO2).
- Used to evaluate exercise intensity and the body’s metabolic state during exercise.
VE/VCO2 Slope
- The relationship between minute ventilation (VE) and carbon dioxide output (VCO2) during exercise.
- A normal range for the VE/VCO2 slope is typically less than 34, indicating normal cardiopulmonary response to physical exertion.
