name the three artificial blood treatments
PLASMA OR SALINE ACTION, PFC'S, haemoglobin based products
1 of 13
and the three artificial heart treatments
artificial valves, artificial hearts
2 of 13
pros and of plasma or saline
buys time for body to make more blood--or for a matched tissue for blood transfusion to be found. It replaces the lost blood volume to keep blood pressure as normal.
3 of 13
cons....
saline doesnt carry oxygen or blood to the heart its only temporary
4 of 13
pros of PFCS's
oxygen dissolves readily in PFCS's, can replace red blood cells, so oxygen can still be carried to the tissues. Dont carry disease, can be kept for a long time.
5 of 13
cons of PFC'S
dont dissolve in water so can be hard to transfer into blood. dont carry as much oxygen as real blood and they break down very quickly so large amounts are needed to supply the body. Can cause severe side effects.
6 of 13
how do PFC'S fit into the damaged capiliaries
they don't contain cells so can fit
7 of 13
pros of HBP
doesnt always need to be kept in the fridge easy storage. the artificial or syntheitc or GE haemoglobin carries even more oxygen than normal blood. So better for body.
8 of 13
cons of HBP
broken down very quickly only lasts 20-30 hours-need alot...-----doesnt clot when wound is created----doesnt fight disease--it also sometimes caused severe problems for patients.
9 of 13
pros of artificial valves
replace damaged or diseased heart valves,,,cant be rejected by the body as have no blood capillary cells.
10 of 13
cons...
risk during surgery
11 of 13
pros of artificial hearts
buys time while wait for a tissue match---gives relatively normal life while they wait as can leave hospital if they want even if it is difficult.
12 of 13
cons ...
risk of blood clotting in heart-can be fatal,,,need alot of machinery to keep it working----not permanent fix.
