PRINCIPLES OF SpO

 OPERATION

The 

Star 55

 monitor

 

provides continuous, non-invasive, automatically calibrated

measurements of both functional oxygen saturation of hemoglobin and pulse rate.

The instrument combines the principles of spectrophotometric oximetry and

plethysmography.  It consists of an electro-optical sensor that is applied to the

patient and a microprocessor based monitor that processes and displays the

measurements. The electro-optical sensor contains two low-voltage, low intensity

light-emitting diodes (LEDs) that serve as light sources and one photodiode as a

light receiver. One LED emits red light (approximately 920nm.)

When the light from the LEDs is transmitted through the blood and the various

tissue components, a portion of it is absorbed . The photodiode in the sensor

measures the light that is transmitted, and this measurement is used to determine

how much light was absorbed.

With each heart beat, a pulse of oxygenated arterial blood flows to the sensor site.

This oxygenated hemoglobin differs from deoxygenated hemoglobin in the amount of

red and infrared light that it absorbs. The 

Star 55

 

measures absorption of both red and

infrared light and uses those measurements to determine the percentage of functional

hemoglobin that is saturated with oxygen.

Initially, light absorption is determined when the pulsatile blood is not present.  This

measurement indicates the amount of light absorbed by tissue and nonpulsatile

blood absorption that does not change substantially during the pulse. This is

analogous to the reference measurement of a spectrophotometer. Absorption is

then measured when the pulsatile blood is present. In that measurement, light

absorption at both wavelengths is changed by the presence of the pulsatile, arterial

blood. The 

Star 55

 then corrects the measurement obtained during the pulsatile flow for

the amount of light that was absorbed at the initial measurement. The ratio of the correct

absorption at each wavelength is then used to determine functional oxygen saturation.
