NICE Guideline Recommendations:
17. Consider single-unit red blood cell transfusions for adults (or equivalent volumes calculated based on body weight for children or adults with low body weight) who do not have active bleeding.
18. After each single-unit red blood cell transfusion (or equivalent volumes calculated based on body weight for children or adults with low body weight), clinically reassess and check haemoglobin levels, and give further transfusions if needed.

Original uncertainty examples Is it better to give a little blood, i.e. 1 unit at a time to top a patient up in the BMT process rather than say a 3 unit transfusion to last a longer time? ~ Why do blood transfusions always include two units and not just one? ~ How much blood can one transfuse in an acute setting?
