Blood flow
Blood Product	Storage	Remarks
Whole blood	CPD-A 35 days	Changes in blood with time: progressive cell alteration, rise in haemoglobin, potassium and plasmatic ammonia products, reduction of potassium in erythrocytes. Gently agitate blood bag twice a week. Thanks to vertical or lateral storage of the bags, shocks are minimized, sorting facilitated, diffusion of oxygen inside the bags and carbon dioxide outside is easier.
Fresh Plasma	24 hours at 1-6°C
Frozen Fresh Plasma	6 month to 1 year between -18°C et -30°C	At -30°C, coagulation factors remain active during one year. At -20°C, in the freezer, coagulation factors remain active during 6 month. For albumin and K-dependant coagulation factors (II, VII, IX, X), shelf life of 3 years. It is not recommended to use an auto-defrost freezer. Once frozen, the bag becomes fragile and has to be handled with carefully. Wrap the bags.
Packed Red Blood Cells	3-4 weeks at 1-6°C	Beyond 2 weeks, do not administer to dogs in a critical state: loss of a part of ATP and of the 2,3DPG of erythrocytes, their membrane becomes rigid and half-life is reduced. Gently agitate blood bag twice a week in order to maintain sufficient rate in ATP and 2,3DPG. Vertical or lateral storage of the bags. Avoid opening and closing freezer too often.
