If I have to stop flow to change IV bags, especially when blood is hanging, should I disconnect the power cable?
Disconnecting the power cable, in effect, turns the heaters off. If left connected, the heaters will cycle to maintain a 38ºC (100.4ºF) fluid temperature inside the device. Blood samples have been evaluated with the heaters on at stop flows for one minute and repeated at a stop flow of five minutes with little to no effect. Stop flow conditions greater than five minutes with the power left connected has not been evaluated.
