2. OVERVIEW
The pulse oxygen saturation is the percentage of HbO2 in the total Hb of
the blood, so-called the O2 concentration in the blood. It is an important
bio-parameter to the respiration. Many of the respiration disease will
cause hypoxemia, even endanger the patient’s health. As a result, mon-
itoring the SpO2 is indispensable in the clinical rescuing. The traditional
method to measure SpO2 is to analyze the sample of the patient’s blood,
so can get the partial pressure of oxygen and calculate the SpO2 by use
the bloodgas analyzer. This method can not be used to monitor continu-
ously. For the purpose of measuring the SpO2 more easily and accurate-
ly, GIMA developed the Fingertip Oximeter. The device can measure the
pulse rate and blood perfusion index simultaneously.
The Fingertip Oximeter is compact, convenient to use and carry and with
low power consumption. You just need to put the ngertip into the sensor
of the device, the SpO2 value will appear on the screen immediately.
2.1 Features
- Small in size and lightweight;
- Color OLED, various display modes, display directions adjustable;
- The device can accurately measure SpO2value, pulse rate value and
perfusion index;
- The device will automatically start measuring after putting nger into
rubber cushions;
- The device will power off automatically without signal for about 8 se-
conds;
- Audible & visual alarm function;
- Low voltage indication;

2.2 Major Applications and Scope
This device is applicable to home, hospital (including internal medicine,
surgery, anesthesia, pediatrics, emergency room etc.), oxygen bar, the
community medical center, alpine area and it also can be used before or
after sports, and the like. The Fingertip Oximeter can detect SpO2 , pulse
rate and blood perfusion index.
This device is not appropriate to be used for continuous mon-
itoring.
2.3 Environment Requirements
Operating Temperature: 5°C~40°C
Operating Humidity: 30%~80%
Atmospheric pressure: 70kPa~106kPa
2.4 SpO2Common Knowledge
1. Meaning of SpO2
SpO2 is the saturation percentage of oxygen in the blood, so called O2
concentration in the blood; it is dened by the percentage of oxyhemo-
globin (HbO2) in the total hemoglobin of the arterial blood. SpO2 is an
important phy¬siological parameter to reect the respiration function; it
is calculated by the following method:
SpO2= HbO2/ (HbO2+Hb)×100%
HbO2are the oxyhemoglobins (oxygenized hemoglobin), Hb are those
hemoglobins which release oxygen
2. Principle of Measurement
Based on Lamber-Beer law, the light absorbance of a given substance
is directly proportional with its density or concentration. When the light
with certain wavelength emits on human tissue, the measured intensity
of light after absorption, reecting and attenuation in tissue can reect
the structure character of the tissue by which the light passes. Due to
that oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin
(Hb) have different absorption character in the spectrum range from red
to infrared light (600nm~1000nm wavelength), by using these charac-
teristics, SpO2 can be determined. SpO2 measured by this oximeter is
the functional oxygen saturation - a percentage of the hemoglobin that
ENGLISH

20
can transport oxygen.
In contrast, hemoximeters report fractional oxygen saturation - a per-
centage of all measured hemoglobin, including dysfunctional hemoglo-
bin, such as carboxyhemoglobin or metahemoglobin.
Clinical application of pulse oximeters: SpO2 is an important physiologi-
cal parameter to reect the respiration and ventilation function, so SpO2
monitoring used in treatment has become more popular. (For example,
such as monitoring patients with serious respiratory disease, patients
under anesthesia during operation and premature and neonatal infants)
The status of SpO2 can be determined in timely manner by measure-
ment and will allow nding the hypoxemia patient earlier, thereby pre-
venting or reducing accidental death caused by hypoxia effectively.
3. Factors affecting SpO2measuring accuracy (interference reason)
• Intravascular dyes such as indocyanine green or methylene blue.
• Exposure to excessive illumination, such as surgical lamps, bilirubin
lamps, uorescent lights, infrared heating lamps, or direct sunlight.
• Vascular dyes or external used color-up product such as nail enamel
or color skin care.
• Excessive patient movement.
• Placement of a sensor on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line.
• Exposure to the chamber with High pressure oxygen.
• There is an arterial occlusion proximal to the sensor.
• Blood vessel contraction caused by peripheral vessel hyperkinesias
or body temperature decreasing.
4. Factors causing low SpO2Measuring value (pathology reason)
• Hypoxemia disease, functional lack of HbO2.
• Pigmentation or abnormal oxyhemoglobin level.
• Abnormal oxyhemoglobin variation.
• Methemoglobin disease.
• Sulfhemoglobinemia or arterial occlusion exists near sensor.
• Obvious venous pulsations.
• Peripheral arterial pulsation becomes weak.
• Peripheral blood supply is not enough.

2.5 Caution
A. The uncomfortable or painful feeling may appear if using the device
ceaselessly, especially for the microcirculation barrier patients. It is
recommended that the sensor should not be applied to the same
nger for over 2 hours.
B. For the individual patients, there should be a more prudent inspecting
in the placing process. The device can not be clipped on the edema
and tender tissue.
C. The light (the infrared is invisible) emitted from the device is harmful to
the eyes, so the user and the maintenance man, can not stare at the
light.
D. Testee can not use enamel or other makeup on the nger.
E. Testee’s ngernail can not be too long.
F. The nger should be placed properly, or else it may cause inaccurate
measurement.
G. Do not shake the nger and keep at ease during using.
H. Do not put wet nger directly into oximeter.
I. The SpO2 sensor should not be used at a location or limb tied with
arterial canal or blood pressure cuff or receiving intravenous injection.
L. Do not x the SpO2 sensor with adhesive or else it may result in ve-
nous pulsation and inaccurate measure of SpO2 .
M.Make sure the optical path is free from any optical obstacles like rub-
berized fabric.
N. Excessive ambient light may affect the measuring result. It includes
uorescent lamp, dual ruby light, infrared heater, direct sunlight and
etc.
O. Strenuous action of the subject or extreme electrosurgical interfer-
ence may also affect the accuracy.

2. DESCRIPTION GÉNÉRALE
La saturation en oxygène de la pulsation est le pourcentage de HbO2
dans le Hb total du sang, et est appelée concentration d’O2 dans le
sang. Il s’agit d’un paramètre biologique important pour la respiration.
Beaucoup de troubles de la respiration peuvent entraîner une hypoxé-
mie, pouvant même mettre en danger la santé du patient. Il est donc
indispensable dans les procédures cliniques de contrôler l’ SpO2 . La mé-
thode traditionnelle pour mesurer l’ SpO2 est celle d’analyser un échantil-
lon de sang du patient, an d’obtenir la pression partielle d’oxygène et de
calculer l’ SpO2 par le biais d’un détecteur approprié. Cette méthode peut
être utilisée pour le suivi continu. An de mesurer l’ SpO2 plus facilement
et précisément, il a été développé l’oxymètre de doigt. Le produit peut
également mesurer simultanément la fréquence cardiaque et l’indice de
perfusion.
L’oxymètre de doigt est un appareil compact, facile à utiliser et à trans-
porter et à faible consommation d’énergie. Il suft d’insérer l’extrémité du
doigt dans le capteur de l’appareil, la valeur de SpO2 et la fréquence des
pulsations apparaissent immédiatement sur l’écran .
2.1 Caractéristiques
- Très léger et compact
- Afchage en couleur OLED avec sélection de différents modes et
choix d ’ orientation.

- Mesure avec précision l ’ SpO2 , la fréquence cardiaque et l ’ indice de
perfusion.
- Démarrage automatique de mesure après l ’ introduction du doigt.
- Arrêt automatique après 8 secondes sans signal.
- Alarmes visuelles et audio.
- Indicateur de batterie faible.
2.2 Principales applications et but du produit
L ’ oxymètre de doigt est adapté tant pour l ’ usage domestique que pour
l ’ usage hospitalier. Il peut surveiller l ’ SpO2 , la fréquence cardiaque et
l ’ indice de perfusion.
Ce dispositif n ’ est pas adapté à la surveillance continue.
2.3 Caractéristiques environnementales
Température de service : 5°C~40°C
Humidité de service : 30%~80%
Pression de service : 70 kPa~106 kPa
2.4 Connaissances communes sur la SpO2
1. Signication de SpO2
La SpO2 est le pourcentage de saturation de l ’ oxygène dans le sang,
appelé également concentration d’O2dans le sang; il est déni par le
pourcentage en oxyhémoglobine (HbO2) dans l’hémoglobine totale du
sang des artères.
La SpO2 est un paramètre physiologique important qui reète la fonction
respiratoire ; il est calculé selon la formule suivante:
SpO2= HbO2/ (HbO2+Hb)×100%
Les HbO2sont les oxyhémoglobines (hémoglobines oxygénées), les Hb
sont les hémoglobines qui relâchent l’oxygène.
2. Principe de la mesure
Fondée sur la loi de Beer-Lambert, l’absorption de lumière d’une subs-
tance donnée est directement proportionnelle à sa densité ou concen-
tration. Lorsque la lumière est émise avec une certaine longueur d’onde
sur le tissu humain, l’intensité mesurée de cette lumière après réexion,
absorption et atténuation sur un tissu permet de déterminer les caracté-
FRANÇAIS

35
ristiques de la structure du tissu à travers lequel la lumière passe. L’hé-
moglobine oxygénée (HbO2) et l’hémoglobine désoxygénée (Hb) ayant
des taux d’absorption différents de plage de lumière spectrale rouge et
infrarouge (600 nm~1000 nm de longueur d’onde) on peut, en utilisant
cette méthode, déterminer le taux de SpO2 . La SpO2 mesurée par cet
oxymètre est la saturation en oxygène fonctionnel-- un pourcentage de
l’hémoglobine qui peut transporter l’oxygène. En revanche, l’hémoxy-
mètre indique la saturation fractionnelle en oxygène – un pourcentage
de toutes les hémoglobines mesurées, y compris les hémoglobines dys-
fonctionnelles, comme les carboxyhémoglobines ou méthémoglobines.
Application clinique des oxymètres de pouls: la SpO2 est un paramètre
physiologique important pour reéter la fonction de respiration et de
ventilation, c’est pourquoi la surveillance de la SpO2 utilisée dans les
traitements a de plus en plus de succès. (comme par exemple, la sur-
veillance de patients avec des troubles respiratoires graves, patients
sous anesthésie durant une opération, nouveau-nés ou bébés préma-
turés). La mesure de la SpO2 permet de déterminer rapidement l’état
de celle-ci et de trouver ainsi l’éventuelle hypoxémie du patient, tout en
évitant ou en réduisant le risque
de mort accidentelle provoquée par l’hypoxie.
3. Facteurs affectant la précision de la mesure de la SpO2(inter-
férences)
• Les colorants intravasculaires comme le vert d’indocyanine ou le bleu
de méthylène.
• L’exposition à un éclairage excessif, comme les lampes chirurgicales,
les lampes à bilirubine, les lampes uorescentes, à infrarouges ou la
lumière directe du soleil.
• Les colorants intravasculaires ou les agents colorants externes
comme les vernis à ongle ou les crèmes tintées.
• Les mouvements excessifs du patient.
• Le placement d’un capteur à une extrémité où est présent un brassard
pour la prise de pression, un cathéter artériel, ou un dispositif intra-
vasculaire.
• L’exposition dans une pièce avec de l’oxygène à haute pression.
• L’occlusion artérielle à proximité du capteur.
• La contraction d’un vaisseau sanguin provoquée par l’hyperkinésie
