Well, you'll surely get exposed to swans and hemodynamics and such..should be a great experience for you. You'll also get your hands on balloon pumps, strykers,
a-lines, cvp's, sheaths, icp-monitors, etc. These are things the ICU people see daily and will without a doubt broaden your experience and help you in any future anesthesia endeavor.
As far as advice?? Well, if you honestly feel this will increase your chances at acceptance into a program, than by all means do it!
I'm sure it took you more than a few months to reach your current 'comfort-zone'...so just go into knowing it may take awhile to reach a new one
Good Luck to you!
