Indications
FAST Exam
Best view for
Pericardial Effusion
detection
Best view in
COPD
and
Asthma
(heart pushed down towards diaphragm)
Overall four chamber heart view
Subcostal view is an oblique cut through the heart (between transverse and longitudinal)
Apical view is preferred four chamber view as more exactly transverse heart view (perpendicular to longitudinal view)
Start position for inferior vena cava view (when difficult to identify in volume low patients)
First obtain four chamber view in subcostal view
Next, rotate the probe 90 degrees into longitudinal subcostal view
Technique
Pearls to improve view window
Liver
provides best window to heart
Consider starting this view longitudinally with indicator at 12:00 to identify left lobe of liver and angle through heart
View improves with the patient taking a deep inspiration
View improves when significant pressure is applied
View worsens in
Obesity
Imagine the probe as a spoon used to scoop out the heart (anology attributed to Cliff Reid, MD)
Increase the depth to maximum initially while obtaining best view of heart
Maneuvers to improve view
Deep breathing
Upright
Posture
and left lateral decubitus position (difficult in
Trauma
patients)
Transducer orientation
Hold transducer over the top (more at the base of probe) to allow for a more shallow angle to abdominal wall (15 degrees)
Push the transducer down (posteriorly) to drop below (deep) to the xiphoid process
Transducer placed sub-xiphoid (by 1-2 cm) in superior epigastrium
Transducer with energy toward left
Shoulder
(indicator aimed at right flank)
Regardless of screen indicator (left or right), probe indicator should match the direction of screen indicator
Screen indicator on right (Cardiac preset, standard
Echocardiogram
)
Transducer indicator pointing towards patient's left (3:00 position)
Screen indicator on left (FAST)
Transducer indicator pointing towards patient's right (9:00 position)
Images
Landmarks
Four chamber heart view
Increase angle of approach (aiming more posterior) if aorta is seen in the four chamber view
Apex of the heart points to screen right when probe and screen marker are oriented correctly
Interpretation
Pericardial Effusion
Systolic Dysfunction
Wall motion abnormalities
