Self-life of the blood components:-


Most of the components in blood have a short self-life. So it must be noted that keeping the continuity of the supply of the components is always a problem. This is the reason auto transfusion is widely chosen in these days. The other notable point is a patient’s blood is continuously salvaged for reinfusion during surgeries. This factor also influences a donor to donate a “self-donated” blood for the future use. Of course, in this case the word “donation” does not get ethically accepted but it has become an idiomatically accepted term in the domain of medical ethics.
