Pulmonary Hypertension Flashcards
1
Q
What happens to the right side of the heart in pulmonary hypertension?
A
It has to work harder. It will first thicken then dilate.
2
Q
At what range for the RVSP is considered pulmonary hypertension?
A
> 30 mmHg
3
Q
What vessel is used to determine the right atrial pressure (RAP)?
A
IVC. Evaluate the size and the ability to collapse
4
Q
What is the formula for Bernoulli equation?
A
4(V)2 - four times the peak velocity squared
5
Q
What is the formula for right ventricular systolic pressure (RVSP)?
A
RVSP = 4(V)2 + RAP - four times the TR peak velocity squared plus the RAP
6
Q
What shape does the LV take when the pressures on the right side are increased?
A
D-shaped - Increased RV pressure cause the septum to press in on the LV
