Fingertip Pulse Oximeter
General Description
Haemoglobin Saturation is percentage of HbO2 (Oxyhemoglobin), compounded with
oxygen, in haemoglobin (Hb). In other words, it indicates the saturation of HbO2 in blood.
It is a crucial physiological parameter for Respiration System. Many respiratory diseases
can lead to decrease of SpO
2
saturation. Moreover, such factors as organic automatic
adjustment malfunction derived from anesthesia, side effect of major operation and
injures aroused from physical check can also cause problems about SPO2 saturation
variation, which contributed to such adverse symptoms such as faint, vomit and feel
weakness and so on. What’s more, if can not get the right remedy, it can lead to dangers
to human’s life. Hence, it is very feasible for doctors to analyze patients’ SPO2
saturation as reference to detect the root of the causes, which is more effective to
relieve patients’ pain and conduct suitable therapy plan as soon as possible.
The fingertip pulse oximeter features of small dimension, low power consumption,
easy-to-use and convenience for carry. As long as you put your finger in the device
which read data though a light-sensitive probe, then the associated reading will be
displayed on the indicator. It is proved by clinical trial Pulse Oximeter have outstanding
precise and could repeat to measure the SPO2 more accurately and stably.
Measurement Principle
The fingertip pulse oximeter contains a dual light source and photodetector.Bone,
tissure, pigmentation, and venous vessels normally absorb a constant amount of light
over time. The arteriolar bed normally pulsates and absorbs variable amounts of light
during systole and diastole, as blood volume increases and decreases. The ratio of light
absorbed at systole and diastole is translated into an oxygen saturation
measurement.This measurement is referred to as SpO
2
.
The principle of the oximeter rely on the property of spectrum which collect data from
hemoglobin and oxyhemoglobin in glow area and area of approximate infrared source
and apply the formular “Lamnert Beer” to establish the evaluating equation. In fact, the
basic calculating technique is to combine electro-photo SPO2 detecting technology with
recording mock pulse rate technology to get the result, the process demonstrate as
below:
Firstly, use glow with wavelength of 660cm and approximate infrared with wavelength of
940cm to put light on the finger tip ready to read analogue data.
Secondly, to process the data by electric circuit and microprocessor, then convey the
data to LED display for reading.

automatically.
Precautions for use
1
Do not use the pulse oximeter in an MRI or CT environment
2
Do not use the pulse oximeter in situations where alarms are required. The
device has no alarms.
3
Explosion hazard:
Do not use the pulse oximeter in an explosive atmosphere.
4
The pulse oximeter is intended only as an adjunct in patient assessment. It must
be used in conjunction with other methods of assessing clinical signs and
symptoms.
5
Check the pulse oximeter sensor application site frequently to determine the
positioning of the sensor and circulation and skin sensitivity of the patient.
6
Do not stretch the adhesive tape while applying the pulse oximeter sensor. This
may cause inaccurate readings or skin blisters.
7
Before use, carefully read the manual.
8
The pulse oximeter has no SpO2 alarms; it is not for continuous monitoring, as
indicated by the symbol.
9
Prolonged use or the patient’s condition may require changing the sensor site
periodically. Change sensor site and check skin integrity, circulatory status, and
correct alignment at least every 4 hours.
Inaccurate measurements may be caused by:
10
Autoclaving, ethylene oxide sterilizing, or immersing the sensors in liquid may
cause inaccurate readings.
11
Significant levels of dysfunctional hemoglobins(such as carbonxy-hemoglobin or
methemoglobin)
12
Intravascular dyes such as indocyanine green or methylene blue
13
SpO2 measurements may be adversely affected in the presence of high ambient
light. Shield the sensor area (with a surgical towel, or direct sunlight, for example)
if necessary.
14
Excessive patient movement
15
High-Frequency electrosurgical interference and defibrillators
16
Venous pulsations
17
Placement of a sensor on an extremity with a blood pressure cuff, arterial
catheter, or intravascular line
18
The patient has hypotension, severe vasoconstriction, severe anemia, or
hypothermia
19
The patient is in cardiac arrest or is in shock
20
Fingernail polish or false fingernails may cause inaccurate SpO2 readings.

WARNING!
Oximeters are not for children’s play. Keep the oximeter away
from young children. Small parts such as the battery door, batteries etc. may
be hazardous if swallowed. The lanyard may cause strangulation in conditions
that may cause it to twist around the neck.
Follow local ordinances and recycling instructions regarding disposal or
recycling of the device and device components, including batteries.
