Q
What causes a right shift of the OXYHEMOGLOBIN DISSOCIATION CURVE?
A
Effect: decreased affinity of Hb for O2 (facilitates unloading of O2 to tissues) —> mer syrgas perifert
- increased PCO2
- hyperthermia
- acidosis
- increased altitude
- increased 2.3-DPG
- sickle cell anemia

Q
What causes a left shift of the OXYHEMOGLOBIN DISSOCIATION CURVE?
A
Increased affinity of Hb for O2 (decreases unloading of O2 from Hb —> mindre O2 perifert)
- decreases PCO2
- alkalosis
- carboxyhemoglobin, methemoglobin
- decreased 2.3-DPG
- hypothermia
- fetal hemoglobin
