U81TO Posted October 6, 2023 Share Posted October 6, 2023 When you have to dilute a RBC to 200ml with a hematocrit of 35% with 0.9% saline, is there a formula to follow? Link to comment Share on other sites More sharing options...
applejw Posted October 9, 2023 Share Posted October 9, 2023 Need more info - what is your starting volume and hematocrit? Use formula C1 x V1 = C2 x V2. DM if you need more - jeanne.towery@prismahealth.org Yanxia and John C. Staley 2 Link to comment Share on other sites More sharing options...
John C. Staley Posted October 9, 2023 Share Posted October 9, 2023 I've always used the C1 x V1 = C2 x V2 formula for such calculations. My question is why do you want a Hct of 35%?? Yanxia 1 Link to comment Share on other sites More sharing options...
Baby Banker Posted October 10, 2023 Share Posted October 10, 2023 We do this occasionally, but we use plasma instead of saline. We use the formula mentioned above. We use RBCs diluted to a specific hematocrit when we have a patient who does not have the blood volume to safely prime an apheresis or dialysis circuit. John C.
