Artificial Blood Flashcards
Name two types of artificial blood
Perfluorocarbons (PFCs) and haemoglobin-based products
What is saline?
Salt and Water
What does saline do?
Replaces lost blood volume to keep blood pressure the same as normal
Why is saline used?
So there is more time for the body to make more blood or for a transfusion match to be found
What can PFCs do that other artificial blood can’t?
Can reach the most swollen body tissues to supply them with oxygen, because PFCs contain no cells
Which type of artificial blood carries more oxygen than normal blood?
Haemoglobin-based products
Which type of artificial blood carries less oxygen than normal blood?
Perfluorocarbons (PFCs)
Disadvantages of both PFCS and haemoglobin based products?
Break down very quickly in the body and can cause severe side effects
Which artificial blood type does not clot or fight disease?
Haemoglobin-based products
What is an advantage of haemoglobin-based products over PFCs
Don’t always have to be stored in a fridge
What are the advantages of PFCs over haemoglobin-based products?
They can be stored for a long time and don’t carry disease
How long do haemoglobin-based products last for in the body?
20-30 hours
Why is it difficult to get PFCs into the blood?
They don’t dissolve in water
