Chapter 1 Introduction
1.1 Brief Introduction
Thank you for purchasing the handheld pulse oximeter. The device is designed to measure SpO
2
and
PR, delivering visual and audio alarm, sensor off alarm. Please read this manual carefully before using
it.
Notice: The illustrations used in this manual may differ slightly from the appearance of the actual
product.
Measurement principle
The principle of pulse oximetry is based on the red and infrared (IR) light absorption of oxygenated
and deoxygenated hemoglobin present in the circulating blood. Oxygenated hemoglobin absorbs
more IR and allows more red light to pass through. Deoxygenated hemoglobin conversely absorbs
more red light and allows IR light to pass through. The detector probe is placed on the finger. The
probe contains two light emitting diodes (LED’s), one in the visible red spectrum. The beams of light
from this probe pass through the tissues and some light is absorbed by the blood and soft tissues
depending on hemoglobin concentration. The amount of light absorption at each light frequency is
dependent on the degree of oxygenation of hemoglobin within the tissues.
The microprocessor can select out the absorbance of the pulsatile fraction of blood, i.e. that due to
arterial blood, from constant absorbance due to non-pulsatile venous or capillary blood and other
tissue pigments

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

Vpod Instruction Manual
8
wrapping the sensor too tight. Inspect the sensor site to ensure the skin’s integrity and the
adhesion position of the sensor is correct. More frequent inspection should be taken if necessary.
Loss of pulse signal can occur in any of the following situations:
a) The sensor is too tight;
b) There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp, or
sunlight;
c) A blood pressure cuff is inflated on the same extremity as the one to which an SpO
2
sensor is
attached.
4.4 Display mode
The handheld pulse oximeter uses an OLED display for a readout. It can display the SpO
2
and pulse
rate (PR) value, as well as a pulse column and SpO
2
waveform.
There are three display modes shown in Fig 7. The first figure is pulse column display mode. The
second figure is the waveform mode. The third figure is line waveform mode indicating SpO
2
% trend.

plethysmogram measurement is
employed to determine the oxygen saturation of hemoglobin in the arterial blood. If , for example,
98% hemoglobin molecules in the red blood cells of the arterial blood combine with oxygen, then
the blood has a SpO
2
oxygen saturation of 98%. The SpO
2
numeric on the Oximeter will read
98%, refer to Fig.7.(2). The SpO
2
numeric shows the percentage of hemoglobin molecules which
have combined with oxygen molecules to form oxyhemoglobin. The SpO
