1. Velocity/intensity: y axis
Bright: Strong Doppler shift (a large # of RBCs moving together).
Dark- weak shift.
2.Time: x axis
3. Audio:Doppler shifts are audible.
Strong well defined signals tell us we parallel & in right region.
Smooth tones= laminar,Harsh= turbulent. |

RV Tilt(RVIT), AV SAX, AP 4CH
Color in each view. Assess w/Doppler in each view. PW at tips.
CW to assess for high vel flow(regurge).
AP 4CH- can slide off axis to bring in RV/TV better. |

| Normmal flow will be diastolic, above baseline w/E & A wave. Regurge will be systolic, below baseline. |

AP 4
Can Doppler in AP 2 or AP Long but not necessary unless pathology present.
PLAX & SAX- not parallel, so will not use spectral. Color valve in each view.
Assess with Doppler, PW in LVIT at leaflet tips. Switch to CW to look for high velocity flow. |

AP 5
Can assess in the AP Long if pathology.
PLAX & SAX not parellel, so will not spectral. Assess with color in all views. Assess with PW in LVOT.
Assess AV with CW to check for high velocity flow. |
