I imagine Hemoglobin as a seat for oxygen to sit on. The RBC is like a bus and wohhoo travels the oxygen to it's destination!
Anyway..
If something doesn't allow oxygen to sit on it seat decreases O2 saturation.
Sit - seat - sat, get it?
Carbon monoxide sat on oxygen's seat. O2 saturation decreases in CO poisoning.
