Documenting pain level during colonoscopy

I'm in the middle of redoing the moderate sedation flowsheet for GI endoscopy in my hospital, and have been looking at lots of different examples. It seems that few hospitals/endo centers document on pain level during endoscopies.

Currently, our flowsheet has a Post-Anesthesia Recovery scale, which I think is not appropriate for procedural sedation. Now I am considering a simple sedation scale along with the Colorado Behavioral Pain Scale, which is an objective 0-10 pain scale. I would love to hear the opinions of other GI nurses regarding pain documentation during endoscopy.
