#veterinary technician

So, I’ve noticed a trend at my new clinic wherein more than one technician has been notating blood pressures like this:

“100, 102, 103 MAP 101″

And I am confused. They’re getting blood pressures with a doppler and it is highly questionable whether or not you can obtain a true diastolic measurement with the doppler, so I’m not sure how they’re doing this.

Unless… they think the MAP is just the average of the three systolic measurements? I was always taught that MAP = DBP + 1/3(SBP-DBP). Am I wrong? The training coordinator is doing this too, so it must be -ME- that is incorrect here. Help!
