Cardiac Pressures Flashcards
RAP: ________
How is RAP estimated?
RAP = 2 - 8 mmHg
From the IVC collapse and diameter.
OR:
By the size and collapse of the IVC and the PK PG of the TR jet velocity, using CW.
RVEDP: _______
RV/PA SP: _______
How is RV/PA SP calculated?
RVEDP: 2 - 8 mmHg
RV/PA SP: 15 - 30 mmHg
With the RAP and TR PG.
MPAP: ________
Calculation for MPAP: _________
