Health Information

Pulse oximetry aims to measure the oxygen saturation of arterial blood. It has become accepted as a standard of care in many areas since its development by Takuo Aoyagi in 1971. However, there is considerable evidence that the principles of pulse oximetry and its important practical limitations are not well understood by many healthcare professionals.

The absorption spectra of haemoglobin and oxyhaemoglobin differ. The relative amounts of each can be detected by considering the relative absorption of two beams of light through perfused tissue at wavelengths where the absorption spectra differ significantly. In practice, wavelengths of 660nm (red light) and 940 nm (infrared) are used in pulse oximeters.

However, other tissues (venous blood, bone, skin, muscle, etc.) also absorb light, so a pulse oximeter looks for the change in absorption over the cardiac cycle due to arterial pulsation. This is due to factors such as changes in diameter of arteries and arterioles, and a change in the axis of erythrocytes. In practice, absorption varies by only 1-2% over the cardiac cycle.

Pulse oximeters use two light-emitting diodes, one for each wavelength, and one photodetector to detect both wavelengths. The absorption for each wavelength will show a constant component (due to tissue, etc.) and a variable component (due to arterial pulsation). The pulse oximeter alters the signals electrically so that the constant component of each is the same, then removes this constant component, leaving variable red and infrared signals (fig.1). The relative sizes of these signals varies with the arterial oxygen saturation. Pulse oximeters measure the ration between these two wavelengths, then use a look-up table to give the oxygen saturation. This look-up table is developed by desaturate volunteers.

As it is considered unethical to desaturate volunteers below 80%, values for saturations less than this are obtained by extrapolation and so are potentially unreliable. Co-oximeters, which use multiple wavelengths of light, are able to differentiate haemoglobin, oxyhaemoglobin, methaemoglobin and carboxyhaemoglobin and measure both fractional and functional oxygen saturation. Pulse oximeters using only two wavelengths cannot do this, but they can be calibrated to display either parameter (with some assumptions). It has been suggested that the figure produced by a pulse oximeter should be defined as “oxygen saturation as measured by a pulse oximeter”

Pulse oximeters are used in many clinical situations and in many are considered a standard of care enabling hypoxic events to be avoided. In other situations, the information they provide simply would not be available without them. The principles underlying pulse oximetry are being used in a number of new developments. Plethysmographic waveforms are being reviewed for use in haemodynamic assessment and multi-wavelength pulse oximetry potentially offers increased accuracy and the possibility of noninvasive measurement of carboxyhaemoglobin, methaemoglobin and total haemoglobin. Whatever the future brings, it will remain as important as it is with current pulse oximetry for the clinician to have an understanding of the principles and limitations of their equipment.
