I understand that in a hypoxic state the body reacts by increasing hematocrit, and in a deyhydrated state the body will obviously have a higher hematocrit... But what about a hyperoxic state?

In hypoxia, erythropoetin production is increased, and increases your red cell count . I do not know if any response would be needed if there were more oxygen than you need.
Too high a level of oxygen can be toxic. Hyperbaric O2 has been known to cause seizures.

theoretically it should drop as the need for red cell is decreased but this takes some time to happen so in the real work someone wouldn't have a high PO2 for long enough for this to occur
