- is the total amount of 02 carried in blood, including bound and dissolved 02.
- depends on the hemoglobin concentration, the Po2, and the P50 of hemoglobin.
- is given by the following equation:
02 content = (02-binding capacity x % saturation) + Dissolved 02 where:
02 content = amount of 02 in blood (ml O^lOO ml blood) 02-binding capacity = maximal amount of 02 bound to hemoglobin measured at 100% saturation (ml 02/100 ml blood) % saturation = % of heme groups bound to 02 (%) Dissolved 02 = unbound 02 in blood (ml 02/100 ml blood)
