Section 2 Introduction
2.1 General
This chapter provides a general description of the A310 Pulse Oximeter including:
Brief device description
Product features
2.2 Indication for use/ intended use
The Pulse Oximeter is a non-invasive device intended for spot checking of functional oxygen
saturation of arterial hemoglobin (SpO2) and pulse rate (PR). This portable device is indicated for use
in adult patients in clinical institution and home environments.
2.3 Brief Device Description
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 Pulse Oximeter can be used to measure human SpO2 and heart rate through finger. The
product is suitable for family, hospital (including clinical use in internist/surgery, Anesthesia,
pediatrics and etc.) Oxygen Bar,social medical organizations, physical care in sports and etc.
2.4 Product Features
Lightweight for carrying and Easy-To-Use.
Manually adjust the direction of interface.
Color OLED display, simultaneous display for testing value and plethysmography.
Low Perfusion: 0.2%. (Advanced DSP algorithm can improve measurement accuracy, under
the condition of low perfusion.)
Visual & Sound reminder function. Real-time spot-checks.
Low Battery voltage indicator.
Automatically switch off.
Standard two AAA 1.5V Alkaline Battery support more than 20 hours continuous work.
CAUTION: The device cannot be used to measure the child below 3 years as the test result is
not guarantee to accurate.
CAUTION: 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.
CAUTION: The patient is an intended operator and can perform the maintenance the
equipment.

5/15
*DSP algorithm: Digital signal processor algorithm.
*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).
PI (Perfusion Index )is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's
peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is an indication of the pulse strength at the
sensor site.
2.5 Expected Service Life
–The expected service life of the ME equipment;
–The expected service life of parts or accessories shipped with the ME equipment;
–Where the shelf life is less than the expected service life, the shelf life of parts or
Accessories shipped with the ME equipment.
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 SpO2 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.
