In May/June I participated in a study that had me dialyzing five nights a week for 8 hours which as far as I know showed that the PHD could be used as a daily nocturnal machine.
Bill, How were you heparinzed during these nocturnal txs.?

Just want to note that it was May and June of 2004.
The heparin was via a bolus at the beginning and then the heparin was infused during the treatment by a stand alone heparin pump. The pump was programed to turn off at a designated time.

Could you give more details on stand alone heparin pump? Does it attach to your access like an IV etc?
