RBC Hemoglobin Content and Concentration

Was reviewing respiratory system, effects of high altitude. Says on my notes from lectures that acute change include hb sat to decrease while hb conc stay normal. After 4 weeks hb sat still low ( as Patm still low causing pO2 to still be low) and hb content increase above 15 (15 g/100 ml blood), hb content would be normal..

Got confused by last two statements: whats the difference between hb content and concentration?

Thanks a lot in advance

Do you mean Oxygen content?

There is two types of oxygen in the blood, bound to hemoglobin and dissolved in plasma. Oxygen content refers to the sum of both. Hemoglobin oxygen saturation refers to that bound to hemoglobin only.
