Maybe someone can help me out here. I always have pts comment on thr color of their blood when starting an IV. some make a comment about how dark it is, others about how bright it is.
Now I obviously understand the difference between arterial vs venous blood and can assure you that the IV is in the venous system when it is started. However, I have noticed varying colors to blood myself when starting lines. Does anyone have more info on what constitutes the darkness or brightness of a patient's blood?
