Introduction
Thank you for buying the GO2Model 9570 Fingertip Pulse Oximeter. This small, portable
device will give you important information about your oxygen saturation (the amount of
oxygen in your blood) and pulse rate at your fingertip! The Model 9570 is easy to use and
needs no routine maintenance except battery replacement. This User Guide explains how to
use and care for your GO2Model 9570.

ENGLISH
Intended Use
GO2Model 9570 is intended to measure blood oxygen saturation (%SpO2) (the amount
of oxygen in your blood) and pulse rate of both adults and children. It is designed for
fingers (not the thumb) between 0.3 and 1.0 inch (0.8 – 2.5cm) thick. The index finger
(pointer finger) is most recommended. Contact your licensed health care professional for
your expected oxygen saturation level (to compare with your readings). The GO2Model
9570 is intended for Home Health Care Only.
Contraindications
 • Do not use the GO2in a magnetic resonance (MR) environment.
Warnings
 • Keep the oximeter away from young children. Small items such as the battery door,
battery, and lanyard are choking hazards.
 • Certain activities may pose a risk of injury, including strangulation, if the lanyard
should become wrapped around your neck. Use the lanyard with caution.

5
Cautions
 • Do not use the GO2as the only basis for making medical decisions. It is intended
only to be used as additional information that you can give to your licensed
health care professional.
 • The GO2might misinterpret excessive movement as good pulse strength. Limit finger
movement as much as possible when using the device.
 • The GO2must be able to measure your pulse properly to give you an accurate reading.
Do not put the device on the same hand/arm when using a blood pressure cuff or monitor.
 • The GO2has no alarms. It will not sound if the amount of oxygen in your blood is low
or if your pulse rate is too high or too low.
 • Do not place the GO2in liquid or clean it with agents containing ammonium chloride,
isopropyl alcohol, or products that are not listed in this User’s Guide.
 • The GO2is not intended for use in institutions.
 • Any of the following conditions may reduce the performance of the GO2:
- flickering or very bright light;
- weak pulse quality (low perfusion);
!

6
ENGLISH
- low hemoglobin;
- arterial catheters;
- nail polish, and/or artificial nails; and
- any tests recently performed on you that required an injection of
intravascular dyes.
 • The GO2may not work if you have poor circulation. Rub your finger to increase
circulation, or place the device on another finger.
 • The GO2measures oxygen saturation of functional hemoglobin. High levels of
dysfunctional hemoglobin (caused by sickle cell anemia, carbon monoxide, etc.)
could affect the accuracy of the measurements.
 • Batteries can leak or explode if used or disposed of improperly. Remove the
battery if the GO2will be stored for more than 30 days.
 • Do not use the GO2in a combustible environment (oxygen enriched environment).
 • Do not use the GO2outside the specified operating and storage temperature ranges.
 • Do not use the GO2for more than 30 minutes without relocating the device to
another finger.

 • The GO2needs to be used according to information provided in the User Guide.
 • Do not tamper with, or hang lanyard from the flexible circuit.
 • Radios and cell phones or similar devices may affect the GO2and should be kept at
least 2 meters (7 feet) away from the device.
 • Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast towers
and TV broadcast towers may affect accuracy.
 • Use in emergency vehicles with communication systems may affect accuracy.
 • Functional tester cannot be used to assess the accuracy of this pulse oximeter.
 • Follow local disposal and recycling laws for the GO2and its components,
including the battery.
 • The GO2is a precision electronic instrument and must be repaired by Nonin
Technical Service.

ENGLISH
Installing the Battery
One 1.5 volt AAA-size (LR03) battery powers the GO2for approximately 2400
measurements. Nonin recommends using alkaline batteries (one is included with
each new GO2). NOTE: You may use rechargeable batteries; however, they may
require more frequent replacement.
1. Remove the battery door located on the left side of the GO2by sliding it
towards you.
2. Insert one new 1.5 volt AAA-size battery. Follow the plus (+) and minus (-) markings
for battery direction (as shown inside of the battery compartment).

3. Carefully reposition the battery door. NOTE: Do not force it into place; it fits only
when positioned correctly.
When battery is low, the battery indicator symbol on the display will flash. Remove battery
if the device will be stored for more than 30 days. Replace low battery as soon as possible.

ENGLISH
Applying the GO2Model 9570 to Your Finger
Hold the GO2with the display facing toward you; slide your finger into the opening
at the bottom of the device, as shown below, until the fingertip touches the built-in
stop guide.
For best results, make sure the finger is centered within the finger guide; keep the GO2
at heart or chest level. The index (pointer) finger is recommended.

NOTE: Correct positioning of the device on your finger is critical for accurate
measurements. While on the finger, do not press the GO2 against any surface and
do not squeeze or hold it together. The internal spring provides the correct pressure;
additional pressure may cause inaccurate readings.

ENGLISH
Activating the Device and Verifying Operation
The GO2automatically turns on when a finger is inserted. When a finger is inserted,
the GO2performs a brief self test, as shown below. Verify that all segments of the
LCD (Liquid Crystal Display) appear during the startup sequence.
The GO2LCD has an integrated backlight that turns on automatically in low light
conditions. This allows the display to be visible in dark spaces.

Reading Your Results
When you put your finger in the GO2, you’ll notice an LCD display come on. The numbers
you see show:
 • the amount of oxygen in your blood, displayed as %SpO2; and
 • your Pulse Rate, displayed as a 2 or 3 digit number, measuring the number
of times your heart beats per minute.
The Pulse Quality indicator ( ) displays the strength of the pulse rate signal. Bars will
display after the , indicating pulse signal strength ( ); the greater the number of
bars indicates a greater pulse quality signal strength.
If you are not getting a pulse rate reading and your pulse quality indicator is weak, warm
the finger or reposition to another finger.
While the GO2is formulating its reading immediately after activating the device, the
sensor disconnect indicator ( ) will appear. The sensor disconnect indicator also appears
when you remove your finger to indicate the pulse signal is not detected or when there is

excessive motion. If this symbol does not turn off while your finger is in the device,
reposition your finger or switch to a different finger.
The Battery indicator symbol shows the battery strength (the less the symbol is
filled – the less battery capacity is available – see chart below). Replace the battery when
this symbol begins to flash.

Care and Maintenance
The GO2requires no calibration or periodic maintenance other than battery replacement.
Wipe the device with a soft cloth dampened with a mild detergent or 10% bleach solution.
Do not use undiluted bleach or any cleaning solution other than those recommended here,
as permanent damage could result. Dry with a soft cloth, or allow to air dry. Clean once
per week or more frequently if handled by multiple users.
Caution: Do not place the GO2in liquid or clean it with agents containing ammonium
chloride, isopropyl alcohol, or products that are not listed in this User’s Guide.
