Cardiac catheterization can measure which cardiovascular parameters?

Cardiac catheterization can measure which cardiovascular parameters?

• A. True
• B. False
• C. Only blood pressure
• D. Only oxygen content

Answer: (A)

Cardiac catheterization provides direct, real-time hemodynamic data. By advancing a catheter into the heart and great vessels, clinicians obtain precise pressure measurements in the right atrium, right ventricle, pulmonary artery, and left atrium (via wedge pressure). Blood samples taken during the study yield oxygen content (saturation) from these sites, helping assess shunts and oxygen delivery. In addition, the procedure can calculate cardiac output using thermodilution or the Fick principle and derive systemic and pulmonary vascular resistances. Because it measures multiple parameters—pressures across chambers and vessels, oxygen content, and flow—the statement is true: cardiac catheterization can measure a variety of cardiovascular parameters, not just one.
