Oh Gawd, really?... that's... scary.
You go from a specialty where you rely on multiple high tech precision monitors, stat data feedback, instant access to therapeutics, that focuses mainly on the cardiovascular, pulmonary, neurologic system... to a specialty where the answer between nothing & limb-life threatening conditions are hidden in the history/physical, labs that don't come back for days, multiple diagnostic uncertainties, therapeutic leaps of faith where access to support is limited?

I'd rather your friend work as a ICU in house cross cover at night or as a house officer/code runner at a nursing home than do ambulatory work... even then, I noticed that many anesthesiologists don't run too many codes, since their training mainly limited them to airway & most OR patients don't/shouldn't krunk...
