Wow...I admit that here in the academic residency world things don't go quickly, but 5-10 minutes seems hard to fathom...
Assuming I wake up the patient as the dressings are going on, it's probably five minutes to get the bed into the room, pt moved over and out the door. Another 10-15 to wheel the pt to the PACU, hook up the monitors, give report, close out the computer chart, and write PACU orders. Then, assuming the next pt is already there and has an IV (which is maybe 60% of the time) another 10 to see and examine/consent the pt, and even then the cleaning staff is still ten minutes away from having the room clean.
Bottom line, I think 30 minutes is about the fastest turnover I've ever seen at our hospital...
