Patients in PEA arrest with organized cardiac activity on bedside ultrasound appear to have better survival than those with disorganized, agonal cardiac activity and may respond to treatments not usually performed in standard ACLS, like continuous vasoactive drips during arrest.

In this small study, IVC collapse of >/= 50% on bedside ultrasound correlated with a CVP </= 8 cm H2O and was 91% sensitive, 94% specific.  But be sure to read the discussion.

Point of care limited ultrasound for trauma, aka FAST exam, reduced time to the OR and several other important secondary outcomes.

Point of care ultrasound may be very useful during CPR, but it should not get in the way of chest compressions.  If you're going to use it, get in there quick and get out of the way or choose a view that allows continuous chest compressions (i.e. subxiphoid).

FAST exam didn't have an impact on the care of stable children with torso trauma.

ED POCUS was very accurate for the diagnosis of dyspnea and led to an answer much faster than standard ED workup.

Bedside echo that answers a specific question, in this case - is the RV dilated or not - may be reliably performed, even by novice sonographers in the ED.

Single view POCUS was just as good as 4-view in detecting clinically significant PTX.

Point-of-care ultrasound is helpful in deciding which skin infections are abscesses vs simple cellulitis.
