Oxygen Dissasociation Curve Flashcards
1
Q
Oxygen dissociation curve goes to the right because ?
A
reduced saturation of Hb with oxygen i.e. enhanced oxygen delivery to tissues
2
Q
Oxygen dissociation goes to the left because
A
increased saturation of Hb with oxygen i.e. decreased oxygen delivery to tissues
3
Q
When would oxygen dissociation curve shift to the right ?
A
RAISED oxygen delivery to tissues
LESS OXYGEN saturated by HB
- acidosis
- hypercapnia
- raised temperature
4
Q
When would oxygen dissociation curve shift to the left?
A
More oxygen in the hb and less delivered to tissues
L = low
HbF,
methaemoglobin, carboxyhaemoglobin
Low [H+] (alkali)
Low pCO2
Low 2,3-DPG
Low temperature
