UK - To apply cardiac resuscitation to the patient
US - To jump start the dude

A bit flip, but again, where's the problem?

Note that the actual US phrases are shorter and less pompus-sounding.

Hello Arny!

That's exactly my point! The simplicity is refreshing. I'm not
belittling simplicity - on the contrary it's an art to say something
with simplicity and impact, especially if it also has an element of
humour. Ad agencies make millions of dollars coming up with simple
phrases that have strong impact. Shakespeare had the knack too and
look where it got him in the Dictionary of Quotations!
