Ok so in class last week we learned about the circulatory system and one of the objectives is to describe how oxygen is carried in the blood. Well while answering that i figured that For every hemoglobin there are four irons that can hold four oxygen's. Well then i thought about sickle cell patients and since the RBC shape is changed would that mean that the hemoglobin in the sickle cell patient would change too? And if it did, does that mean that each sickle cell would carry less oxygen than a normal cell, and even though SPo2 measures the oxygen in the blood in a sickle cell patient would it be decreased oxygenation at the cellular level as compared to a non-sickle cell patient or would a sickle cell patients body just create more sickle cell RBC's to compensate? Is it too much to think about or am i just being geeky
