Q. Regarding the O2 dissociation curve: (Solved)
1. increased PCO2 has a direct effect on the curve, shifting it to the right
2. 2,3-DPG levels rise as altitude
3. the deoxy form of Hb is in the relaxed state
4. CO moves the curve to the left as it has 100 times the affinity of O2 for Hb
5. P50 is at a PO2 of 40mmHg
- b. 2,3-DPG levels rise as altitude
