I. Introduction
In Pulse Oximetry, Peripheral Oxygen Saturation (SpO2) refers the indirect
measurement of the specific oxygen content in the blood. More specifically, it is
expressed as a percentage of haemoglobin containing oxygen (oxygen-saturated
haemoglobin) to the total amount of haemoglobin in the blood
(oxygen-saturated/unsaturated haemoglobin).
The haemoglobin is an iron-containing protein bound to red blood cells that
transports oxygen from the lungs to the rest of the body
SpO2is a very important parameter to know the health status of an individual.
The normal SpO2values for a healthy individual are between 95 -100 percent.
In general, the normal values of oxygen saturation shall not be lower than 94
percent. If the measured value of oxygen saturation is lower than 94 percent, an
insufficient supply of oxygen is considered. Many chronic pulmonary or
respiratory related diseases cause to lower the percentage of oxygen saturation
in the human blood. It is important for people with breathing and heart problems
to monitor their SpO2values in a timely manner.
The Pulse Rate (PR) is the number of pulse beats per minute. Normally, the
pulse rate is consistent with the heart rate. In general, the pulse rate of every
people is 60 to 90 beats per minute.
The Perfusion Index (PI) usually reflects the limb perfusion status of an
examined patient, and shows the detection precision of the instrument as well;
that is, examination can still be performed even in the low or weak perfusion
condition. The PI of a normal human body is 3% or greater.
Pulse Oximetry is particularly convenient for noninvasive continuous method of
measurement for blood oxygen saturation, pulse rate and strength; and
perfusion index.
II. Overview
Pulse Oximeter is a small clip-like device usually placed on a patient’s
fingertip. It is based in full digital technology, non-invasive technique to monitor
the oxygen level in your blood. It functions by shining light through your finger.
The sensors detect how much oxygen is in your blood based on the way the light
passes through your finger. It also measures the pulse rate and strength.
A finger pulse oximeter is simple, easy, portable and convenient to use; cheap
and commonly used. Because of its simplicity of use and the ability to provide
immediate readings that are of critical importance in emergency medicine. It is
a very useful monitoring device for patients with respiratory or cardiac problems
to monitor their oxygen saturation levels in timely manner. It also useful for
mountain climbers and athletes whose oxygen levels may decrease at high
altitudes or any physical activity or exercise.
It now used routinely in critical care, monitoring rooms, hospitals (including
operation rooms of the departments of internal medicine and surgery, the
department of anesthesiology, the department of pediatrics, and intensive care
rooms), oxygen bars, social medical care institutions, sports & health and
typically found in ambulances. It is not advisable to use for a continuous
monitoring to any patient. And it is appropriate to use before and after, but not
during the actual physical activities to undertake.
A. Principle of Pulse Oximeter
The principle of a Pulse Oximetry is based on the red and infrared light
absorption characteristics of oxygenated and deoxygenated hemoglobin.
Oxygenated hemoglobin absorbs more infrared light and allows more red
light to pass through. Deoxygenated (or reduced) hemoglobin absorbs more
red light and allows more infrared light to pass through.
Modern Pulse Oximeter consist of a peripheral probe together with a
microprocessor unit displaying a waveform, the oxygen saturation and the
pulse rate. The probe is placed on the digit, earlobe or nose. Within the probe
are two LEDs, one in the visible red spectrum (660nm) and the other in the
infrared spectrum (940nm).
The beams of light pass through the tissues to the photodetector. During
passage through the tissues some light is absorbed by blood and soft tissues
depending on the concentration of hemoglobin. The amount of light
absorption at each frequency depends upon the degree of oxygenation of
hemoglobin within the tissues.
Detection of oxygen saturation of hemoglobin by spectrophotometry is based
on Beer-Lambert law, which relates the concentration of solute to the
intensity of light transmitted through a solution.

VIII. Troubleshooting
A. Inaccurate Readings
■Inaccurate measurement may be caused by autoclaving, ethylene,
sterilizing oxide, liquid immersing in the sensors, high-frequency electro
surgical interference.
■Avoid unnecessary body movements to be able to get a stable and an
accurate SpO2, PR and PI values.
■The patient may suffer from hypertension, severe vascular atrophy, severe
anemia or low oxygen.
■The patient is in sudden cardiac arrest or shock state.
■The fingertip nail to be measured is using a fake nail or has a nail polish.
■For longer measurements, periodically change the contact position
between the probe of the Pulse Oximeter and the fingertip.
■Check the integrity of the skin and the blood circulation condition of the
finger.
The functional tester shall not be used to evaluate the accuracy of the probe
of the Pulse Oximeter.
The Pulse Oximeter has a specific calibration curve, and is precise for the
combination of the mainframe and probe of the Pulse Oximeter. If the functional
tester can measure the portion of overall errors of the mainframe-probe system
of the Pulse Oximeter attributable to the mainframe of the Pulse Oximeter, the
functional tester can test the accuracy of a Pulse Oximeter that duplicates the
calibration curve.
