The average increase in hematocrit for each of the 16 groups of rats exposed to CHx. Hematocrit was recorded in both chamber control adult rats and adult rats adapted to CHx to verify that hypoxia had been achieved in the adult rats adapted to CHx. The hematocrit was 47.2 ± 0.2% for chamber control animals (n=44). The average change in hematocrit (18.7 ± 0.8% for all CHx animals (n=79) (P<0.0001)) was significantly increased in all sixteen groups of adult rats adapted to CHx. The height of each bar represents the mean change in hematocrit for each group adapted to CHx and the error bars represent 1 SEM (n=4-6 for each group).
