One of the practical considerations in FAST image acquisition is moving the patient’s arms, particularly when the cot sides are elevated. Obviously this can be difficult in a resuscitation setting.
Pericardial View
For the pericardial view, try the sub-typhoid approach first. Alternatively, the parasternal view may be better. In this instance, the marker should point down to the heart apex to gain a standard view.
Learning Bite
The marker on the probe should always be orientated towards the patient’s head, or to their right (except in the parasternal view)
RUQ view
Imagine the probe is a torch and imagine shining it towards the internal area which you want to see. For the RUQ view, start on the right side and site the probe just anterior to the mid-axillary line, angled and slightly backwards, to look at the anterior aspect of the renal capsule.
Learning Bite
For RUQ and LUQ views, start at the mid-axillary line and angle the probe slightly backwards: the LUQ probe position is always slightly higher.
LUQ view
The LUQ view is a little more difficult to obtain as the left kidney is higher than the right and therefore the view through an intercostal window may need to be obtained. Site the probe just posterior to the mid-axillary line, angled and slightly backwards, to look at the anterior aspect of the renal capsule.
Pelvis Sagittal View
For the pelvis sagittal view, position the probe as shown. A traverse view should also be obtained.
