Fingertip pulse oximetry

General description

Oxygen mixes with blood in the lungs and is transported in

blood mainly by hemoglobin. Chemically the oxygen molecule

combines loosely and reversibly with the heme portion of the

hemoglobin. The amount of oxygen that combines with the

hemoglobin is determined by the partial pressure of oxygen.

The amount of oxygen in blood, expressed as a percentage of

hemoglobin saturation is a measure of oxygen (SaO2) in the

artery and is estimated by a pulse oximeter as an SpO2 reading.

The amount of oxygen in blood (as measured by the pulse

oximeter SpO2 reading) is a very important physiological

parameter in respiratory and circulatory systems. Many respiratory

diseases reduce the oxygen-hemoglobin saturation in human

blood. Moreover, factors such as Automatic Organic Regulation

Malfunction caused by anesthesia, trauma resulting from major

surgery or medical examination, or other diseases due to virus or

bacteria can also cause a reduction in oxygen hemoglobin

saturation in arterial blood which can be detected by the pulse

oximeter through a low SpO2 reading. This can result in symptoms

such as depression, vomiting, and asthenia in patients.

The ngertip pulse oximeter is a compact, low-power consumption,

portable device. When the index nger is inserted into the ngertip

photoelectric sensor, the display screen of the Braun Pulse oximeter

will show the measured value of %SpO2 and pulse rate as well as a

vertical bar graph showing the pulse amplitude.

Measurement principle

Pulse oximetry is based on the dierence in the selective

absorption of red light by oxygenated blood or oxyhemoglobin

(HbO2, which is bright red) as compared to deoxyhemoglobin

(Hb, which is dull red) or de-oxygenated blood. This selective

absorption is based on the Beer Lambert Law. A red (660nm)

and infrared LED (940nm) on the top portion of the prospective

clamp nger-type sensor emits light at these two frequencies.

The red light transmitted through the nger is selectively

absorbed by the oxygenated arterial blood and the remaining

light is detected by a photodetector on the lower portion of the

clamp nger. The infrared light then passes through the nger

without any selective absorption and is detected by the

photodetector on the lower side of the clamp. The transmitted

light captured by the photodetector is converted into a voltage

or current signal and then passed through signal conditioning

and ltering circuits using a microprocessor. %SpO2 is then

derived by analyzing the changes in the amplitude of these

pulsatile signals derived from the photodetector and calibrating

them using pulse scanning and recording technology. The pulse

rate is then derived from these associated waveforms.
