Sure, it would be a pain if it involved those kinds of logistical challenges. If your VA were like the one I am talking about, you literally have 6 different options that always seem available within the building.
Having done it for quite awhile now, I definitely have felt more carryover. Maybe psychologists are unlikely to be in a situation where they need to use CPR, but for me I always felt pretty good after a 2 year refresher for a brief amount of time, followed by a sense of dread should anything come up where I had to do anything until I had a refresher again nearly 2 years later.
