5 SpO2
5.1 Overview
Blood oxygen saturation (SpO2) is the percentage of oxyhemoglobin (HbO2) capacity bound
by oxygen in the blood in the total hemoglobin (Hb) capacity that can be combined, that is,
the concentration of oxygen in the blood.
The principle for monitoring the pulse SpO2is to fix the probe fingerstall on the patient’s
finger, use the finger as a transparent container for hemoglobin, use 660nm wavelength red
light and 905nm near-infrared light as the incident light, maximum output power is 300 mW,
measure the light transmission intensity through the tissue bed, and calculate the concen-
tration of hemoglobin and SpO2.
The passing lights depend on a variety of factors, most of which are constant. However, one
of these factors, the arterial blood flow, changes with time, as it is pulsating. By measuring
the light absorbed during pulsating, it is possible to obtain the arterial blood SpO2. Detection
pulsation can give a “plethysmography” wave and pulse rate signal.

The main screen displays “SpO2” value and “plethysmography” wave. While the monitor gets
and displays the physiological signal from a patient, the pulse tone which is the auditory
information signal. The volume of this pitch tone is user adjustable.
This pulse oximeter applies to measure SpO2of adults (>18 years), pediatric (<18 years,>30
days), neonate (<30 days). Contact SpO2probe to Patient’s finger to get “SpO2” value and
“plethysmography” wave.
SpO2function of this pulse oximeter has been calibrated in factory.
NOTE
•
Information about wavelength range can be especially useful to clinicians.
5.2 Safety information
WARNING
•Please use SpO2 sensor supplied from Bistos, operate in accordance with the
Manual, and observe all warnings and precautions.
•Before monitoring, check whether the sensor probe is normal. When SpO2
sensor probe is unplugged from the socket, the screen will display “SpO2 No
Sensor connected” error message, and trigger an audible and visual alarm sim-
ultaneously.
•If the sensor or sensor packaging has signs of damage, do not use this SpO2
sensor; return it to the manufacturer.
•If there is carboxyhemoglobin, methemoglobin or dye diluted chemical, the
SpO2value will have deviation.
•When the patient has a tendency to hypoxia, use the oximeter to analyze
blood samples in order to fully grasp the patient's condition.
•Do not put the sensor on limbs with arterial duct or intravenous tube.
•Do not intertwine electrosurgical equipment cable with the patient cable.
•Avoid using the pulse oximeter and sensors while using the NMR equipment,
in order to avoid severe burns to the patient as a result of induced currents.
•During long time continuous monitoring of a patient, check the position of
SpO2sensor once every 2 hours, and move properly when the skin changes or
every four hours. Some patients may require more frequent inspection, such
as patients with perfusion disorders or sensitive skin, because persistent and
prolonged monitoring may increase unpredictable skin changes, such as aller-
gies, redness, blistering or pressure necrosis.
•Before using, verify compatibility between the monitor and probe, otherwise it
may cause injury to the patient.
•Functional testers cannot be used to evaluate the accuracy of pulse oximetry.

NOTE
•Do not put the oxygen probe and blood pressure cuff on the same limb, be-
cause blood flow occlusion during blood pressure measurement will affect the
SpO2readings.
•The pulse oximeter cannot be used to verify the accuracy of SpO2probe and
SpO2equipment.
5.3 Monitoring steps
(1) Act the appropriate SpO2sensor according to the patient.
(2) Turn on the pulse oximeter, and connect the SpO2sensor probe to the pulse oximeter.
(3) Clean the measurement site, such as finger with nail polish.
(4) Put the SpO2sensor probe on the patient’s finger.
(5) Select the appropriate alarm settings.
(6) Start monitoring.
NOTE
•When you turn on the pulse oximeter, plug in SpO2probe and connect pa-
tient’s finger (or toe), monitor displays SpO2 wave, “SpO2Pulse Search” dis-
played in the technical alarm area until the monitor measured SpO2value and
pulse rate. “SpO2Search Timeout” displayed in the technical alarm area until
the pulse oximeter measured pulse rate. Check the sensor mounting position,
whether the sensor is damaged or sensor type. Reconnect the sensor or use
new sensor.
•The alarm message for signal inadequacy such as “SpO2 No Sensor connect-
ed”, “SpO2 Sensor Off”, “SpO2 Search Timeout”, “SpO2 Signal Unstable”,
“SpO2 Sensor Error” and low priority alarm and indication for signal instability
like “---” are meaning that the value of SpO2 or PR might be inaccurate.
5.4 Setting SpO2
Select the main screen to enter the SpO2 set interface
Select “Wave Speed” and set wave speed to “12.5mm/s” or “25mm/s”. The faster speed,
the smoother wave.
