Q: In which of the following conditions, Pulmonary-Arterial-Diastolic-Pressure (PADP) is usually higher 6 or more than to Pulmonary Wedge Pressure (PWP or PAOP)?

A) Acute Cardiogenic shock
B) Cardiac Tamponade
C) Ventricular Septal Defect
D) Acute Right heart failure
E) Pulmonary Hypertension


Answer: E

PADP is usually either near equal or higher than PWP but if this difference exceeds more than 6, it may be calling to consider pulmonary hypertension.

Pearl: If PWP/PAOP is higher than PADP, it is an error.
