Critical Care Ultrasound

Question 1

How do you calculate the RVSP?

Answer 1

RVSP= 4(tricuspid regurgitant jet velocity)^2 + RAP

Question 2

How is MPAP calculated?

Answer 2

MPAP= (PASP + 2PADP)/3

Question 3

What are the echo findings consistent with tamponade?

Answer 3

RV collapse during diastole when it should be filling, >40% variability in tricuspid E velocity, >25% variability in mitral E wave velocity
