californiacls Posted September 20, 2013 Share Posted September 20, 2013 A few days ago at work i was dispensing a unit of PRBC to a nurse. She noticed that the unit was slightly darker than other units. She asked me why this was, and i did not know the answer. So my question is, why is some units of PRBC bright red and others more darker? Link to comment Share on other sites More sharing options...

Deny Morlino Posted September 20, 2013 Share Posted September 20, 2013 That was my thought Scott. Oxygenation levels vary from one person to another. Link to comment Share on other sites More sharing options...
Mabel Adams Posted October 19, 2013 Share Posted October 19, 2013 sometimes if the donor is a smoker they have enough carbon monoxide in their blood to make it look brighter red--or so I've been told. Link to comment Share on other sites More sharing options...
