Number of Point of Care Blood Gas (epoc) devices

The way I would break this down would be: 2500 tests per month /30 days= an average 83 test perday. Those 83 tests per day are then further divided up by 9 analyzers giving 9.26 tests per analyzer per day. Now if the nurses are using the maximum amount of time to perform those tests, 10 minutes, then each analyzer is used: 9.26 tests * 10 minutes= 92.59 minutes per day. 
Another way you could look at it is that you run 2500 tests per month/ 25 beds= 100 tests per room. So in a month each room is technically only using: 100 tests per room/ 30 days= 3.33 tests per room per day.
I think this is less a "not enough equipment" problem and more a poorly scheduled patient testing problem, such as all the patients needing blood gasses at the same time. 
Hope that helps!

I see it the same as Amelia. 3 tests per room per day. 9 EPOCs can be shared (1 EPOC per 3 rooms) more or less. That would mean 1 EPOC for 3 rooms would run about 9 tests daily. I think this is an opportunity for a workflow process improvement. Buying that amount of EPOCs is costly as well as maintenance, contracts, supplies, etc.
