Key Definitions Of Oxygen Dissociation Flashcards
1
Q
What is oxyhaemoglobin?
A
Oxygen bound to a haemoglobin eg. HbO8
2
Q
What is oxygen dissociation?
A
Where oxygen detaches from haemoglobin
—> usually at respiring tissue cells.
3
Q
What is affinity (of haemoglobin for oxygen)?
A
How strongly haemoglobin attracts oxygen
4
Q
What is % haemoglobin saturation with oxygen?
A
% of haemoglobin bound to oxygen
Number of oxyHb molecules / max number of Hb molecules (x100)
5
Q
What is partial pressure of oxygen (pO2)?
A
The “concentration” of oxygen in the air/ environment.
6
Q
What is partial pressure of carbon dioxide (pCO2)?
A
The “concentration” of carbon dioxide.
