Pulmonary Capillary Wedge Pressure (PCWP) Example

This page shows you the Pulmonary Capillary Wedge Pressure (PCWP) example which will guide you in a simple manner to calculate the Average of the lateral and septal E values and mean Pulmonary Capillary Wedge Pressure by just substituting the inputs in the PCWP by E/e' (Nagueh Formula).

PCWP by E/e' Calculation Example

Example :

Let us consider the problem with the value of the early diastolic velocity of the lateral mitral annulus as 4 , the value of the early diastolic velocity of the medial mitral annulus as 3 and the value of mitral inflow E velocity as 2. Find PCWP?

Solution:

We can calculate the Pulmonary Capillary Wedge Pressure (PCWP) using the given PCWP by E/e' (Nagueh Formula).

Formula:

e = (l + s) / 2 p = (1.24 x (E / e)) + 1.9 Where, e = Average of the Lateral and Septal E Values l = Early Diastolic Velocity of Lateral Mitral Annulus s = Early Diastolic Velocity of Medial Mitral Annulus E = Mitral Inflow E Velocity p = Mean Pulmonary Capillary Wedge Pressure

Substituting the values in the formula,

Average of the Lateral and Septal E Values = (4 + 3) / 2; Average of the Lateral and Septal E Values = 3.5

Mean Pulmonary Capillary Wedge Pressure = (1.24 x (4 / 3.5)) + 1.9; Mean Pulmonary Capillary Wedge Pressure = 3.884

Therefore, the values of Average of the lateral and septal E is 3.5 and Mean Pulmonary Capillary Wedge Pressure is 3.884.
