PSAX Doppler Protocol Flashcards
what do you do differently for PSAX AV colour than PLAX
Zoom for PSAX
PSAX AV colour box should be wider than ____
AV annulus
can you see regurg with PSAX AV Colour
yes
simultaneous biplane colour AV
shows PLAX/PSAX same time (only some machines can do this and its not many)
PSAX Colour IAS (not in SAIT protocol) we want to lower colour scale to ____
40cm/sec
PFO
patent foramen ovale
PSAX TV Colour we will ____ and have the colour box just as wide as the ___
sector down
annulus
PSAX TV CW cursor will be placed ______ or ____ if no jet
center of TR jet
TV coaptation zone
PSAX TV CW has baseline set _____ with ____m/sec below baseline even if no TR is seen
1/4 from top
2.4m/sec
when do we measure a jet for PSAX TV Colour
is a parabolic jet is seen
up to ____ of us have some TR
80%
PSAX PV Colour has PR seen as a ____ on the _____ side of the PV
red flame
RVOT
PSAX RVOT/PV Spectral doppler shows ___ and __
PR
RVOT
PR (AKA, ____ velocities, PW/CW)
pulmonary insufficiency
high
CW
RVOT (____ velocities, PW/CW)
slower
PW
PSAX PV PW has sample volume ___ on the RV side of the PV
5mm
PSAX PV PW has baseline __
higher than mid (not by a lot)
what do we look for on PSAX PV PW to know we are near the valve
closing click
what do we measure in the PSAX PV PW
PAT
PAT what/AKA
Pulmonary acceleration time
AKA RVAcT
we want a ____ sweep to measure PAT
fast
PAT is used to calculate the _______
meanPA pressure
normal PAT
> 120 ms
PSAX RVOT PW asses the _____ velocity
RV outflow
PSAX RVOT PW: if PV has regurg, it is ignored for ___ because optimization of spectral should be on ____
PW
foward flow
what do we measure for PSAX PV CW found where in calc package
peak velocity
found in vessels screen of calc package
PSAX RVOT CW when regurg is present you a) or b)
a) take 2 images (optimized for outflow/optimized for regurg)
b) take one image showing both outflow/regurg
PSAX CW PV: use CW to interrogate the PV for _____ and _____
PV regurg
PV stenosis
PSAX MV Colour has colour box slightly wider than ____
Mv
if you saw MR in plax you should also see it in
PSAX MV colour
PSAX Colour IVS with sweep is to look for abnormal flow across the IVS indicating _____
ventricular septal defect (VSD)
