CHAPTER 1 INTRODUCTION
1.1 Brief Introduction
Thank you for using the handheld pulse oximeter. The main functions of this device
are to measure SPO2 and PR, visual and audio alarm, sensor off alarm, data storage
and replay etc. Please read the operator’s manual carefully before operating it.
Application range: The device is used to monitor patient’s arterial oxygen saturation
and pulse rate continuously.
1.2 Safety Information
!
●The handheld pulse oximeter is to be operated by qualified personnel only.
Before using, carefully read this manual, directions for using of accessory, all
precautions, and all specifications. The user must check that the equipment
functions safely and ensure that it is in proper working condition before being
used.
●The is intended for use only as an adjunct in patient assessment. It must be
used in conjunction with clinical signs and symptoms.
●To avoid an electrical hazard, never immerse the unit in any fluid or attempt to
clean it with liquid cleaning agents. Always take out the batteries before
cleaning.
●If oximeter becomes accidentally wet during use, stop operation of the oximeter
until all affected
components have been cleaned and permitted to dry completely. Contact your
local representative if additional information is required.
●If any parameters displayed on oximeter is not accurate, adopt the other
methods to diagnosis patient.
●The medical equipment must be manipulated by personnel who have already
gotten the relative training of operation.
●For safe and accurate operation, use only recommended accessories. Request
for the special children or infant accessories, when monitoring infant or
▒▓ www.OctiveTech.com Operating Instructions
4
children.
●Do not use the oximeter in the presence of a flammable anesthetic mixture with
air, oxygen or nitrous oxide
●Alarm must be set up according to different situation of individual patient. Make
sure that audio sound can be activated when alarm occurs.
● For proper equipment maintenance, perform the service procedures at the
recommended intervals as described in the manual.
●Do not use the oximeter during Magnetic Resonance Imaging (MRI) scanning.
Induced current could potentially cause burns. The oximeter may affect the
MRI image, and the MRI unit may affect the accuracy of oximeter measurements.
● The oximeter can monitor only one patient synchronously.
●As to the other points for attention, please carefully read the relevant chapter in
this instruction.
1.3 Electromagnetism interference
The oximeter is low power consumption device. It will not interference
surrounding people, device and environment. Nevertheless, if there is strong
electromagnetic interference near the equipment, it may result in harmful
interference, even makes performance inactivate. Therefore, if any the warp of
anticipated effect appears, you should firstly prevent, identify and solve the
adverse electromagnetic interference, then proceed to use the device.
To reduce possible problems caused by electromagnetic interference, we
recommend the following:
1. Interference from adjacent radio or mobile phone.
If the radio is the interference source, install the equipment in other place. If the
mobile phone is the source, make it far away from the equipment.
2. Direct and indirect electrostatic discharge:
Before using equipment, make sure operator and patient who touch the
equipment have no direct or indirect electrostatic power. Damp room is helpful to
remit such problem.

4.2 SPO2 (Arterial oxygen saturation) Monitor
4.2.1 Chief introduction
What is SpO2 Monitoring?
SpO2 plethysmogram measurement is employed to determine the oxygen
saturation of hemoglobin in the arterial blood，that is the percentage of hemoglobin
molecules and oxygen molecules。For example, 97% hemoglobin molecules in the
red blood cells of arterial blood combine with oxygen, then the blood has a Spo2
oxygen saturation of 97%，the Spo2 numeric on the monitor will read 97%.The Spo2
numeric shows the percentage of hemoglobin molecules that have combined with
oxygen molecules to form oxhemoglobin. SpO2 /PLETH parameter can also
provide a pulse rate signal and a plethysmogram wave.
How do the SpO2/PLETH parameters work?
Arterial oxygen saturation is measured by a method called pulse oximetry. It is a
continuous, no-invasive method. It measures how much light, sent from light
sources on one side of the sensor, is transmitted through patient tissue to a
receiver on the other side.
The amount of light transmitted depends on many factors, most of which are
constant. However, one of these factors is blood flow in the arteries varies with
time, because it is pulsating. By measuring the light absorbing
during the pulsation, it is possible to get the oxygen saturation of arterial blood.
Detecting the pulsation gives a PLETH waveform and pulse rate signal.
Spo2 value is shown in the form of numerical value, PLETH waveform is shown in
the form of graph on the screen.

▒▓ www.OctiveTech.com Operating Instructions
17
Warning：If there is carbon oxygen hemoglobin, high iron hemoglobin or dye
dilution agent on the sensor, it would lead to inaccurate Spo2 value.
4.2.2 Monitoring Spo2%/Pluse rate
Warning：Do not tangle with SpO2 cable with the wires of ES(Electro surgery)
equipment.
Warning：Do not put the sensor on extremities with arterial catheter or
venous syringe.
Caution ：Do not perform SpO2 measuring and NIBP measuring in same arm
at one time, because obstruction of blood flow during NIBP
measuring may adversely affect the reading of SpO2 value.
SpO2 plethysmogram measurement
 Select the appropriate type and size sensor
 Attach the sensor to the appropriate site of the patient finger
 Plug the connector of sensor into SpO2 socket on the top panel of pulse
oximeter.
Fig 4.1 placement of the sensor
4.2.3 Limitation for measurement
In operation, the accuracy of oximetry readings can be affected by the following
factors.
4.2.3.1 Whether the performance of measurement is content or not depends on the
pulsant in the artery. The measurement would not be performed if the following
instances come across in operation:
 Shock
 Low temperature of hand
 Have taken vascular activity medicine
 Anemia
4.2.3.2 Whether the performance of measurement is content or not also depends
on the absorption of oxyhaemoglobin and deoxyhemoglobin for special wavelength.
▒▓ www.OctiveTech.com Operating Instructions
18
If there are substances absorbing the same wavelength, which would induce false
or low SpO2 value, for examples:
 carboxyhemoglobin
 methemoglobin
 methylene blue
 Indigo carmine
4.2.3.3 Extreme illumination would affect the Spo2 measurement, using
nontransparent cover to shield the sensor would get the better performance.
Note：Pulse sensor should obviate the light source, e.g. radial lamp or
infrared lamp.
Prolonged and continuous monitoring may increase jeopardy of unexpected
change of dermal condition such as abnormal sensitivity, rubescence,
vesicle, repressive putrescence, and so on. It is especially important to check
the sensor placement of neonate and patient of poor perfusion or immature
dermogram by light collimation and proper attaching strictly according to
changes of the skin. Check per 2~3 hours the sensor placement and move it
when the skin deteriorates.

Do not immerse sensor completely in water, Do not immerse sensor completely in
water solvents or cleaning agent because the sensor and connector are not
waterproof.
If cable is damaged, please stop using it immediately
Cleaning：
Moisten the soft cloth or gauze with alcohol and use it to wipe the surface of
sensor, and then use the clean cloth to dry it .The same method can be used
to clean the light source and photo detector.
Cable can be disinfected by 3% of hydrogen-peroxide or 70% of isopropyl
alcohol. Do not immerse the connector into the liquid.
4.3 Alarm
There are three level alarms in oximeter:
High level: “DO-DO-DO---- DO-DO”indicates
 There are some problems with module, which can’t be used.
 The measured value exceeds the set limit, please pay attention to it.
Alarm sound: it is triggered once per 8 seconds. Alarm light: 2 times per
second, light on for half second,
light off for another half second.
Medium level: “DO-DO-DO” indicates:
 The value of the PR exceeds the alarm limit.
 Pleth waveform cannot be detected.
Alarm sound: once per five seconds. Alarm light: once per 2 seconds, light on for
one second, light off for another one second.
Low level: “DO-” indicates Probe off
Alarm sound: once per 5 seconds. Alarm light: once per 4 seconds, light on for
one second, light off for three seconds.
The setups of the audio and visual alarm can be alternated, please refer to the
Chapter 3 in details.
