Carboxyhemoglobin

FCOHb is the fraction of total hemoglobin (ctHb) which is present as carboxyhemoglobin (COHb). By convention the fraction is expressed as a percentage (%).

In the range of 0 – 60 % COHb in arterial (COHb(a)) and venous blood (COHb(v)) is similar, i.e. either venous or arterial blood may be analyzed [1]. In most medical texts FCOHb(a) is referred to as simply COHb. [2]
