Q
What two conditions can cause the oxyhemoglobin dissociation curve to shift right?
A
The Bohr effect (right shift) can be caused by:
- HbSS (sickle cell Hgb)
- Sulf-Hb (sulfhemoglobin)
2
Q
What conditions can cause the oxyhemoglobin dissociation curve to shift to the left?
A
Left shift (Haldane effect) can be caused by:
- Met-Hb (methemoglobin - genetic, car exhaust, drugs)
- Fetal Hgb
- CO-Hb (carboxyhemoglobin)
