33. Approximately…
 FAST can detect
between 100-250ml
 0.5 cm in Morison's
Pouch = 500ml
 1 cm in Morison's Pouch
= 1000ml
CT can detect volumes
of free fluid as low as
100ml

34. Extended FAST (eFAST)
 Evaluation of pneumo and
hemothorax in addition to
intraperitoneal injuries.
 Hemothorax
 Ultrasound is much more
sensitive for detecting pleural
fluid and can identify as little
as 20mL in the pleural space
 Pneumothorax
 Using ultrasound to
evaluate for a
pneumothorax is a
relatively new concept but
it is easy to learn
