Other method takes advantage of the varying conductivities of blood at. different concentrations of blood. In Hemoglobincyanide method hemoglobin is chemically converted to form a cyanmethemoglobin. which is having maximum absorption around 540nm wavelength. The hemoglobin concentration is determined.
Oxyhaemoglobin absorbs more infrared light than deoxyhaemoglobin. Pulse oximeter: This shines light through a finger which is detected on the other side of the probe. It typically shines red light (wavelength 660nm) and infrared light (940nm) separated by a brief pause, multiple times per second. Processing: Light shone through the finger is detected on the other side.
