under the “Setting mode” will be saved, at the same time, the system will exit from “Setting mode”. 

Notices:   
1. 

To confirm the modification, the act of pressing both buttons simultaneously must be fleet. Do not 

press them for long time. 

2. 

When setting date and time, please don’t insert finger. 

Cancel and exit from “Setting mode” 

Under the Setting mode, double-press the Function button, the modification under “Setting mode” will 

be cancelled and simultaneously, the system will exit from “Setting mode”. 
If  there  is  no  operation  under  Setting  mode”  for  more  than  30  seconds,  the  system  will  exit  from 

“Setting mode” automatically.     

CHAPTER 4 Take a measurement 
4.1 Monitoring 

SpO

2

 measuring is a non-invasive technique used to measure the amount of oxygenated hemoglobin 

and pulse rate by measuring the absorption of selected wavelengths of light. The light emitted by a red 

and infrared light-emitting diodes passes through the tissue and is converted into electrical signals by 

a photodiode. 
After  finishing  the  settings  contained  in  chapter  3,  plug  your  finger  into  the  sensor  shown  as  the 

following picture: 
   

 

Fig 6 placement of the sensor 

  Select the suitable sensor in terms of type and dimension. 

    Clip  the  sensor  to  the  rational  position  of  the  patient  finger.  And  ensure  that  the  patient’s  nail 

surface is facing upward. 

  Plug sensor into SpO

2

 port on top panel of pulse oximeter.   

Notice:   

To  maintain  the  highest  degree  of  accuracy,  it  is  recommended  that  the  finger  and  the 

oximeter sensor/probe are kept as still as possible. 

4.2 Mode switch 

After  turning  on  the  oximeter,  each  time  the  function  button  is  pressed,  the  oximeter  will  switch  to 

another display mode, shown as Fig.7. 

4.3 Factors that may affect the measurement 

During operation, the accuracy of oximeter readings can be affected by the following factors: 
4.3.1  Instrument  performance  depends  on  the  pulsatile  character  of  the  artery.  The  measurement 

would  not  be  considered  reliable  and  accurate  if  the  following  conditions  are  present  during 

measurement:   

 Shock or cardiac arrest 

 Temperature of the digit 

 After the administration of a cardiovascular drug 

 Anemia 

 Evidence of ventilation-perfusion mismatch 

4.3.2  Instrument  performance  depends  on  the  wavelength  absorption  for  oxyhemoglobin  and 

deoxyhemoglobin. If there are substances absorbing the same wavelength, this would induce false or 

low SpO

2

 values. The following may affect these values:     

carboxyhemoglobin 

methemoglobin 

methylene blue 

Indigo carmine 

4.3.3  Extremely  high  illumination  could  affect  the  SpO

2

  measurement.  Use  a  semi-translucent  or 

opaque cover to shield the sensor. 
4.3.4

 

Other factors

 

a) High-frequency electrosurgical interference from external devices, including defibrillators.   

b) Placement of a sensor on an extremity that currently has installed a blood pressure cuff, arterial 

catheter, or intravascular line; 

c) The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia; 

d) An arterial occlusion proximal to the sensor. 

 

Warnings 

Use  only  SpO

2

  sensors  provided  by  manufacturer.  Other  SpO

2

  sensors  may  cause  improper 

performance. 

Do not use an SpO

2

 sensor with exposed optical components. 

Excessive patient movement may cause inaccurate measurements. 

Tissue  damage  can  be  caused  by  incorrect  operation  or  misusing  sensor;  for  example,  by
