Blood administration is one of the skills I have todo for check offs this semester and our teachers are unavailable to help with explainin the steps. They told us to watch a video that was done, but I am confused about some parts and really want to get it figured out. The part I'm not sure about is the white flow regulator and switching to normal saline after the blood has finished. Does the white flow regulator need to be pushed in when you put the cassette in the pump? And when you open the ns clamp to let it run after the blood do you have to reset the rate? Thanks to anyone who can help me out here.
