What is the purpose of the PAPI score?

• A. Differentiate between cardiac and respiratory failure
• B. Identify fluid overload
• C. Differentiate between LV and RV dysfunction
• D. Measure blood pressure response to fluids

Answer: (C)

The PAPI (Pulmonary Artery Pulsatility Index) score is primarily utilized to assess the functionality of the right ventricle (RV) compared to the left ventricle (LV) in patients, particularly those with critical conditions such as severe respiratory distress or pulmonary hypertension. The score is derived from hemodynamic parameters obtained from pulmonary artery catheters, and it helps clinicians determine the adequacy of RV function, which is crucial since RV failure can significantly impact patient outcomes in various settings, including ECMO management. By evaluating the pulsatility of the pulmonary artery pressure waveforms, the PAPI score provides insights into the relative performance of the RV. This is vital because RV dysfunction can lead to inadequate cardiac output and compromised tissue perfusion. Therefore, the correct answer directly correlates with the score’s main clinical utilization in differentiating between different types of cardiac dysfunction, particularly in patients who are critically ill.
