Study Notes
Doppler Effect
- The Doppler effect equation is used to calculate the frequency shift of a wave.
Echocardiography
- The Doppler angle determines the blood flow velocity in echocardiography.
Color Doppler
- Color Doppler display represents blood flow velocity and direction in blood flow imaging.
Optimizing Color Flow Doppler
- Factors to consider when optimizing color flow Doppler include: • Gain • Pulse repetition frequency (PRF) • Wall filter • Baseline shift
Color Flow Imaging
- Color flow imaging can identify: • Turbulent flow • Laminar flow • Blood flow velocity • Blood flow direction
Heart Sounds
- Refer to Chapter [X] of the textbook for more information about heart sounds.
Kahn Academy Video
- The first Kahn Academy video to watch for this lesson is titled "[Video Title]".
Wiggers Diagram
- The Wiggers diagram is used to illustrate the relationship between the ECG and heart sounds.
Blood Flow Patterns
- The two types of blood flow patterns discussed in the lesson are: • Laminar flow • Turbulent flow
Cardiac Murmur
- A cardiac murmur is an abnormal sound produced by turbulent blood flow in the heart.
