The evaluation of a photometer (the Radiometer OSM2) for the determination of haemoglobin concentration and per cent oxyhaemoglobin and carboxyhaemoglobin in blood.
Haemoglobin concentration and its saturation with oxygen and carbon monoxide were estimated in identical blood samples using an automated two-wavelength photometer (the Radiometer OSM2) and standard methods. The instrument was easy to operate and maintain and, in general, was accurate and repeatable. At carboxyhaemoglobin levels below 1.5%, however, the precision of the instrument was poor.
