Oxygen Dissociation curve Flashcards
1
Q
Shifting the dissociation curve to the left does what to oxygen delivery?
A
Lowers oxygen delivery
2
Q
Shifting the curve to the right does what to oxygen delivery?
A
Increases oxygen delivery
3
Q
List 5 factors that shift the curve to the left
A
HbF Low pC02 (hypocapnia) Low 2,3-DPG Low H+ (alkali conditions) Low temperature / hypothermia
4
Q
List 4 factors that shift the curve to the right
A
Pyrexia (raised temperature) / hyperthermia
Raised pC02 / hypercapnia
Raised 2,3-DPG
Raised H+ (acidic conditions)
