Our PACU requires PALS, ACLS, BLS and 2 years critical care experience. I worked ICU 3 years and ER for 8 before applying to PACU.
Hey, you've got nothing to lose but a hour or so for an interview. Go for it if that's what you want.
We have to do call, one night a week and every sixth weekend. Trust me, call sucks. If your not one of those people who can fall asleep easily.
Also, at least in our PACU. When you get called in at 2 a.m. for an appy or C-section or bowel resection - your the only nurse alone with the patient. You have to be confident in your skills and abilities - it can be unnerving at times, especially when the patient begins to take a turn for the worst. Again, for a while anyway, your all alone. Have to be able to think on your feet - and yes, have enough respect from anesthesia that they give you a little leeway with autonomus decisions. Like giving Benadryl when the patient developed hives and difficulty breathing after being given Morphine for pain. I called anesthsia, but they took 15 min to get back to me, she could have died, so I took the chance they would cover me and gave the benadryl.
Pacu, in my opinion, is not for the faint of heart. In ICU or the ER you have other staff to back you up, in PACU, you don't. My boss will say "Use the OR Circulating nurse if you need a hand. Heck, they are out of there within 15 to 30 min, for the remainder of the time, I'm alone.
If you thnk you can handle it, and like a challenge, go for it.
