Curvilinear/large convex probe is ideal but phased array probe may be substituted
Linear probe for lung sliding though curvilinear or phased array probes can be substituted with depth decreased
Sequence traditionally varies based on mechanism
Blunt trauma starts with RUQ view
Most sensitive view for peritoneal free fluid
Penetrating trauma starts with cardiac view
Rule out pericardial effusion and (impending) tamponade
Include cardiac, RUQ, pelvic, LUQ views, and pulmonary views
Most sensitive view for peritoneal free fluid
Rule out pericardial effusion and (impending) tamponade
Subxiphoid
Parasternal long, if abdomen distended or subxiphoid view difficult to obtain
Visualize the heart and pericardium using the liver as an acoustic window
Note that an anterior fat pad can give the impression of pericardial effusion but should not be seen on posterior views
Coronal view over the right flank
Visualize the hepatorenal interface
Liver tip is a common location for missed free fluid
Sagittal view just superior to the pubic symphysis
Identify the bladder
This view will be limited after Foley insertion to drain bladder
Coronal view over the left flank
Identify the space between the spleen and diaphragm and the splenorenal interface
Diaphragm should be visualised through the 9 o'clock position
Coronal view over the right and left diaphragm (curvilinear probe)
Sagittal view over the midclavicular line between the 2nd and 3rd intercostal space (linear probe)
Identify the interface between the diaphragm and lung on right and left (curvilinear probe)
Identify lung sliding between two ribs over the anterior thorax (linear probe)
Scan anterior to posterior over the diaphragm on right and left (curvilinear probe)
Hold probe in place between rib space observing for movement along the pleural line (linear probe)
