Abstract
Haemoglobin concentration and its saturation with oxygen and carbon monoxide were estimated in identical blood samples using an automared two-wavelength photometer (the Radiometer OSM2) and standard methods. The instrument was easy to operate and maintain and, in general, was accurate and repeatable. A t carboxyhaemoglobin levels below 1.5%, however, the precision of the instrument was poor.
