e-mar scanning in PACU

I have a question for those nurses who are currently using e-mar scanning to administer meds in PACU. How is it
working for you? Our unit "goes live" with e-mar scanning next week. We will not be allowed to go back and document, all VS and meds must be documented at the exact time given. Sometimes I am up to 30 minutes (or more) behind on charting if the patient is high needs or unstable. I am wondering what other nurses are doing in
regards to e-mar scanning. Thanks in advance for any information you can provide.
