reversibly to Hb‚ however‚ due to the greater affinity of CO as compared to O2‚ CO not readily displaced at normal O2 concentrations: it does not spontaneously displaced from Hb but is displaced by mass action of O2. CO level in blood is represented as the percentage of Hb in the form of carboxyhemoglobin (COHb) which is a Hb-CO complex. Human body have 0.1-1.0% (Mercury‚ 1990)‚ 0.4-0.7% (Widdop‚ 2002) endogenous COHb saturation produced through the process of natural degradation of Hb. The rate of
