What is the normal peak VO2 range during cardiopulmonary exercise testing?

• A. 15-20 cc/kg/min
• B. 20-25 cc/kg/min
• C. 25-35 cc/kg/min
• D. 30-40 cc/kg/min

Answer: (C)

The normal peak VO2 range during cardiopulmonary exercise testing typically falls within 25-35 cc/kg/min. This measurement represents the maximum volume of oxygen that an individual can utilize during intense exercise, providing insight into the functional capacity of the cardiovascular and respiratory systems. Individuals with heart failure often demonstrate reduced peak VO2 levels due to diminished cardiac output, increased pulmonary pressures, and impaired oxygenation. Understanding the normal range allows healthcare providers to assess the severity of the condition, tailor interventions, and monitor progress over time. This value is essential for evaluating exercise capacity and overall fitness levels, which is critical in managing patients with heart failure. In contrast, the other ranges provided do not accurately reflect the expected levels for a typically healthy adult, as they fall below or above the typical physiological range observed in the population.
