As very rule of thumb (guesss)- we would recommend about 1200 to 1500 items of Biomedical equipment per year. We have pushed this to about 1800 items per Biomed per year (but the Biomed does very little of anything else).
You might want to flesh that out a bit, Phil.
Do you mean PM? What kit (defibs?); and how often?

Or would I be right in reading that as:- "typical total number of equipment checked (PM'd?) per biomed per year"?
