Co poisoning causes left shift of oxygen dissociation curve ...decrease in the p50 ...increase in the
affinity...decreased release to tissues and tissue hypoxia. answer 5 it is increased rate of O2 binding to available Oxygen instead of reduced Oxygen binding site.. hope this helps...

3 is definitly correct... but i also see mylife_step1's concern. If CO is readily binding to Hemoglobin, thus taking up binding spots... wouldnt O2 binding rate also be reduced?
It would certainly seem that 3 and 5 are both correct? ne thoughts??

I think it is 3. Since tissue hypoxia not arterial hypoxemia, it cares about the O2 release.

yep agree with you armani but answer 5 is reduced rate of oxygen binding to AVAILABLE hemoglobin...

AVAILABLE Hemoglobin means hemoglobin that is not bind to CO...
