In simple anemia or polycythemia the p50 dose not change, but the oxygen content will change.
Oxygen content increase with polycythemia and decrease with anemia. P50 will stay close to 25.
this is question in NBME 12
it asks which decrease with anemia , I know no direct relation to P50 , but id HB decrease that would decrease the P50 required for HB saturation ????
there was also another option which is decrease arterial O2 binding capacity , which was choosen by the key and I could not undertand why??
PLEASE, PLEASE, PLEASE DONT ASK QUESTIONS FROM NBMES WITHOUT PUTTING IT IN THE TITLE OF THE QUESTION! That is just really unfair.
