Haemoglobin Saturation Flashcards
1
Q
What happens to final O2 molecules as saturation of haemoglobin increases?
A
Becomes harder for the final O2 molecules to bind
2
Q
What shape is the oxygen dissociation graph?
A
S
3
Q
What does 100% oxygen saturation mean on the oxygen dissociation graph?
A
Every haemoglobin is carrying four oxygens
4
Q
What does 0% oxygen saturation mean on the oxygen dissociation graph?
A
No haemoglobin molecules have any oxygen bound
5
Q
How does affinity for oxygen affect saturation?
A
The higher the haemoglobin’s affinity for oxygen, the higher the oxygen saturation
