Normal Color Doppler Flashcards
Is the TRICUSPID VALVE measured in systole or diastole?
diastole BC TV OPENS- flow should be going towards transducer
What THREE views can TV COLOR DOPPLER be taken at? Draw and Color
- A4
- PSAX- AV Level
- RVIT
When measuring TV, can you PW, CW or both?
both
What is a NORMAL velocity for TRICUSPID VALVE?
< .7 m/s or 70 cm/s
What does it mean if the velocity of TV is abornomal?
it is greater than .7 m/sec so either
- RA pushing increased volume through TV
- TV is stenosed
Draw out EKG and waveform of TV
Is the MITRAL VALVE measured during systole or diastole?
diastole when MV opens
What 3 views can be used to measure MV COLOR? Draw and Color
- A2
- A3
- A4
CW or PW or both for MITRAL VALVE?
both
What is the normal velocity for MITRAL VALVE?
< 1.3 m/s or 130 cm/s
What does it mean if there is an abnormal MITRAL velocty?
velocity is greater than 1.3 m/s and either
- LA is volume overloaded
- MV is stenosed
Draw out EKG and waveform of MV
Is the DAo measured in diastole or systole?
systole when AV is open
Do you measure DAo in PW, CW or both?
both
What view do you measure DAo in? Draw and Color
SSN- suprasternal notch
What is the NORMAL velocity for DAo?
< 1.0 m/s
Draw EKG and waveform of DAo
Flow reversal in DAo is due to what?
flow into coronary arteries
Is the PULMONIC VALVE measured in systole or diastole
systole when PV is open
Is the PV measured in CW, PW OR BOTH?
both
In what view to do doppler PV? Draw and Color
- AV level
- rvot
What is the NORMAL velocity of the PULMONIC VALVE
< 1.3 m/sec
What does it mean if theres abnormal velocity flow of PV?
means velocity is greater than 1.3 m/s so
either
- theres an increased volume out of RV
- PV is stenosed
Draw out EKG and waveform for PULMONIC VALVE
Is LVOT doppler done in systole or diastole
systole when AV opens
Is LVOT done in PW, CW or BOTH
PW only
What is the NORMAL velocity of LVOT?
< 1.1 m/s
What does it mean if LVOT velocity is abnormal?
means it i greater than < 1.1m/s bc either,
1. outflow tract is moving an increased volume so has to move it quicker or
2. obstruction in outflow tract
What views do you doppler LVOT? Draw and Color
A5 or A3
Draw out EKG and waveform for LVOT
Is AORTIC VALVE/ASCENDING AORTA doppler done in systole or diastole
systole when AV opens
IS AV/ASC Ao done in PW, CW , or BOTH
CW ONLY
In what views do we doppler AV? Draw and Color
- A5
- A3
- SSN
What is the normal velocity for AORTIC VALVE?
< 1.7 m/s
Draw out EKG, VIEW and waveform for AV in A5 and A3
.
Draw out EKG, VIEW and waveform for AV in SSN
Is PULMONARY VENOUS INFLOW done in systole or disastole
both
What is the normal velocity for PULMONARY VENOUS INFLOW
norm will come later
In what view do we doppler PULMONARY VENOUS INFLOW. Draw and Color
A4
Do we doppler PULMONARY VENOUS INFLOW IN CW,PW or BOTH
PW only bc CW would detect flow from anywhere
Draw EKG and WAVEFORM for PULMONARY VENOUS INFLOW
Why is there flow reversal in PULMONARY VENOUS INFLOW?
some flow volume goes into mitral valve and some into pulmonary veins
Is SVC/ Hepatic Doppler done in systole or diastole
systole and diastole
Is SVC/Hepatic Doppler done in PW, CW, or BOTH
PW
Draw EKG and WAVEFORM for SVC/ Hepatic
What causes S WAVE in SVC/HEPATIC
flow enters RA and TV closes but RA is still filling with volume
What causes D WAVE IN SVC/HEPATIC
TV opens during diastole then second volume into RA
In what view do we doppler SVC or Hepatic? Draw and Color
SC- IVC
