Safety
Instructions for the Safe Operation and Use of the
A310B Pulse Oximeter
Do not attempt to service the A310B Pulse Oximeter. Only
qualified service personnel should attempt any needed
internal servicing.
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 2 hours.
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.
The following reason will cause interference to the testing
accuracy of the pulse oximeter.
High-frequency electrosurgical equipment.
Placement of a sensor on an extremity with a blood pressure
cuff arterial catheter, or intravascular line
The patient has hypotension severe vasoconstriction severe
anemia or hypothermia.
The patient is in cardiac arrest or is in shock.
Fingernail polish or false fingernails may cause inaccurate
SpO2 readings.

Introduction
2.1 General
This chapter provides a general description of the A310B Pulse
Oximeter including:
Brief device description
Product features
2.2 Brief Device Description
A310B Pulse Oximeter
7
The Pulse Oximeter, based on all digital technology, is intended
for noninvasive spot-check measurement of functional oxygen
saturation of arterial hemoglobin (SpO2). Advanced DSP algorithm
can minimize the influence of motion artifact and improve
measurement accuracy of low perfusion.
The Oximeter can be used to measure human Hemoglobin
Saturation and heart rate through finger. The product is suitable
for family, hospital (including clinical use in internist/surgery,
Anesthesia, pediatrics, intensive care and etc.) Oxygen Bar, social
medical organizations, physical care in sports and etc.
2.3 Product Features
Lightweight for carrying and Easy-To-Use.
Manually adjust the direction of interface .
Color OLED display, simultaneous display for testing
value and plethysmogram.
Low Perfusion : 0.2%. (Advanced DSP algorithm can
improve measurement accuracy, under the condition of low
perfusion.)
Visual & Sound alarm function. Real-time spot-checks.
Wireless Bluetooth for data transmission.
Low Battery voltage indicator.
Automatically switch off.
Standard two AAA 1.5V Alkaline Bаttеrу support more
than 20 hours continuous work.

*DSP algorithm: Digital signal processor algorithm.
CAUTION: The device cannot be used to measure the child
below 1 years as the test result is not guarantee to accurate.
CAUTION: The fingertip 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
CAUTION: A function tester cannot be used to assess the
accuracy of a pulse oximeter monitor or sensor.
Clinical testing is used to establish the SpO2 accuracy. The
measured arterial hemoglobin saturation value (SpO2) of the
sensor is compared to arterial hemoglobin oxygen(SaO2) value,
determined from blood samples with a laboratory CO-oximeter.
The accuracy of the sensors in comparison to the CO-oximeter
samples measured over the SpO2 range of 70 -100%. Accuracy
data is calculated using the root-mean-square(Arms value) for
all subjects. Only about two-thirds of PULSE OXIMETER
EQUIPMENT measurements can be expected to fall within
±Arms of the value measured by a CO-Oximeter.
Pulse simulator shall be used to assess Pulse rate
Accuracy. The measured pulse rate is compared to the preset
pulse rate value in simulator. Accuracy data is calculated using
the root-mean-square (Arms value) for all subjects.

*Low Perfusion: In physiology, perfusion is the process of a body delivering blood to a capillary
bed in its biological tissue. Under the condition of low perfusion, the measurement of
non-invasive saturation of pulse-blood oxygen is low-accurate.
*Plethysmograph: is an instrument for measuring changes in volume within an organ or
whole body (usually resulting from fluctuations in the amount of blood or air it contains).
