Bloody good stuff

Blood Transfusions are amazing things. Donated blood is Kristi's life line. For all of the technological wonder of chemotherapy, none of it would be possible without replacing her blood supply. Soon, more than 90% of her blood will be from others. She isn't being given "whole blood". Hers is a "filtered blood product". Removing lymphocytes (white blood cells) can really reduce allergic reactions and improve the shelf life of blood supplies. Blood transfusions in medicine have a very interesting and long history. Early experiments involved cross-species transfusions. There was a belief in the 17^th century that moods could be altered based on the animal from which the blood is taken. Gentle lamb's blood would be calming. Modern blood transfusions came into their own during the first world war. The discovery of blood types and "Rhesus" blood groups (Rh+/-) were important. Prior to this discovery, many people died from immune reactions. The survival rate was improved by mixing the donor and recipient bloods and watching for coagulation.

Kristi just received her 3^rd round of chemo; red stuff and a bag. Between the blood and Daunomyicin push, her cheeks are quite rosy. She's a bit sleepy, but perking up thanks to the first of two pints of blood. As soon as the next unit arrives, we are going out for laps.
