CO-oximeter Components
The Rapidpoint 405 system contains the CO-oximeter (CO-ox)
measurement module that provides the capability for measuring the
concentration of total hemoglobin and hemoglobin fractions (tHb, FO
2
Hb,
FHHb, FMetHb, FCOH) in whole blood samples.
Measurement occurs as the sample flows through the sample chamber.
Light is transmitted, through a fiber bundle, to the optics head. As the
sample flows through the sample chamber, the light is focused from one
side of the optics head through the sample. The light is collected at the
other side of the optics head and then is carried through a fiber bundle to
the polychromator to be measured.
