Q

19
Q

order of assessing A5C Doppler (3)

A

LVOT/AV/Ao. colour doppler
LVOT PW
AV CW

20
Q

LVOT used ____ doppler and assesses for ______ and obtains _____ for calculation

A

PW
LVOT obstruction
VTI

21
Q

AV used ___ doppler and assesses _____ and _____

A

regurgitation
stenosis
(if present)

22
Q

is some aliasing allowed in A5C colour? why?

A

yes as it has the highest V in heart

23
Q

how to adjust 2D A5C image before PW

A

place SV at AV
may slide laterally and dig in indicator so LVOT = 0 degrees
walk PW into LVOT until the veolcity decreases and waveform rounds

24
Q

A5C LVOT PW baseline set

A

1/4-1/3 from top

25
Q

what should you see in the A5C LVOT PW

A

AV closing click

26
Q

what do we measure in the A5C LVOT PW

27
Q

VTI

A

velocity time integral

28
Q

35
Q

AI is shown ____ the baseline (A5C)

36
Q

A3C AV colour must show colour into

A

ascending aorta

37
Q

all the A3C spectral parameters are _____ as the A5C
