We exchanged a berlin today - 1220 -[date redacted] because of clot.When we hooked up the new pump it was not emptying well nor was it filling well.We had given epi and the pressure was high so first i thought the systolic was just high and we could not pump.I turned the sys pressure up to 250 from 220 and no change.As we got the pressure down into the systolic of 80's from 130's there was still not good emptying.In fact it was maybe 30 % fill and 30% emptying.So i started to hand pump rapidly to get some hope of output.Dr [redacted] came back and we decided to change the pump.I went to prime a new pump, was back in a few minutes and we exchanged the pump again at 1245.The new pump was emptying and filling good even with high systolic's.Not sure what was the problem.
