Intended Use
GO2 LED Model 9571 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 de-
signed for fingers (not the thumb) between 0.3 and 1.0 inch (0.8 – 2.5cm) thick. The GO2
LED Model 9571 is intended for low perfusion conditions as defined in the specifications
in this manual. Limit finger movement as much as possible when using this device. Con-
tact your licensed health care professional for your expected oxygen saturation level (to
compare with your readings). The GO2 LED Model 9571 is intended for Home Health
Care Only.
Contraindications
• Do not use the GO2 LED in 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.

Cautions
• Do not use the GO2 LED as 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 GO2 LED might misinterpret excessive movement as good pulse strength. Limit
finger movement as much as possible when using the device.
• The GO2 LED must 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 GO2 LED has 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 GO2 LED in liquid or clean it with agents containing ammonium chloride,
isopropyl alcohol, or products that are not listed in this User’s Guide.
• The GO2 LED is not intended for use in institutions.
• Any of the following conditions may reduce the performance of the GO2 LED:
- flickering or very bright light;
- weak pulse quality (low perfusion);
- 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 GO2 LED may not work if you have poor circulation. Rub your finger to
increase circulation, or place the device on another finger.
• The GO2 LED measures 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 GO2 LED will be stored for more than 30 days.
• Do not use the GO2 LED in a combustible environment (oxygen enriched environment).
• Do not use the GO2 LED outside the specified operating and storage temperature ranges.
• Do not use the GO2 LED for more than 30 minutes without relocating the device
to another finger.

• The GO2 LED needs 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 GO2 LED and 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 GO2 LED and its components,
including the battery.
• The GO2 LED is a precision electronic instrument and must be repaired by Nonin
Technical Service.
Installing the Battery
One 1.5 volt AAA-size (LR03) battery powers the GO2 LED for approximately 2,400
measurements. Nonin recommends using alkaline batteries (one is included with
each new GO2 LED). 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 GO2 LED by sliding it
towards you (see page 9 diagram).
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 numeric displays flash once per second. Replace battery as soon as
possible. Remove battery if the device will be stored for more than 30 days.
Applying the GO2 LED Model 9571 to Your Finger
Hold the GO2 LED with 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
LED at heart or chest level.

ENGLISH
NOTE: Correct positioning of the device on your finger is critical for accurate
measurements. While on the finger, do not press the GO2 LED against any surface and
do not squeeze or hold it together. The internal spring provides the correct pressure;
additional pressure may cause inaccurate readings.
Activating the Device and Verifying Operation
The GO2 LED automatically turns on when a finger is inserted. When a finger is inserted,
the GO2 LED performs a brief self test, as shown below. Verify that all segments of the
LED (Light Emitting Diode) display appear during the startup sequence.

Reading Your Results
When you put your finger in the GO2 LED, you’ll notice an LED display come on. The num-
bers 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.
At the bottom of the display window, a tricolor LED Pulse Quality Indicator shows the pulse
signal quality, while blinking at the corresponding pulse rate. This display changes colors to
alert you to changes in pulse quality that may affect the readings: green - good pulse signal,
yellow - marginal pulse signal, and red - an inadequate pulse signal.
If you are not getting a pulse rate reading and your pulse quality indicator is marginal or
inadequate, warm the finger or reposition to another finger.
After the startup sequence, the GO2 LED begins sensing the pulse (indicated by the blinking
pulse quality indicator). Allow the device to stabilize, observing about 4 seconds of continu-
Pulse Quality Indicator
Percent Oxygen Saturation
Pulse Rate
ous green-colored pulse quality before relying on the displayed values. It is common for the
displayed values to fluctuate slightly over a period of several seconds. If the pulse quality
indicator blinks yellow or red, try another finger.
A minus sign (-) appears in the left-most digit of the %SpO2 display when the GO2 LED
senses that the finger has been removed. The last measured SpO2 and pulse rate values
freeze for 10 seconds, then the device turns off. The device will automatically shut off (to
conserve battery life) approximately 10 seconds after the finger is removed, or after a
2-minute period of inadequate pulse signals.

Equipment Response Time Testing Summary
SpO2 accuracy and low perfusion testing were conducted by Nonin Medical, Inc., as described below:
SpO2 Accuracy Testing
SpO2 accuracy testing is conducted during induced hypoxia studies on healthy, non-smoking, light- to dark-
skinned subjects during motion and no-motion conditions in an independent research laboratory. The measured
arterial hemoglobin saturation value (SpO2) of the sensors 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-squared (Arms value) for all subjects, per ISO 9919:2005, Medical Electrical Equipment–Particular
requirements for the basic safety and essential performance of pulse oximeter equipment for medical use.
Pulse Rate Motion Testing
This test measures pulse rate oximeter accuracy with motion artifact simulation introduced by a pulse oximeter
tester. This test determines whether the oximeter meets the criteria of ISO 9919:2005 for pulse rate during
simulated movement, tremor, and spike motions.
Low Perfusion Testing
This test uses a SpO2 Simulator to provide a simulated pulse rate, with adjustable amplitude settings at various
SpO2 levels for the oximeter to read. The oximeter must maintain accuracy in accordance with ISO 9919:2005 for
heart rate and SpO2 at the lowest obtainable pulse amplitude (0.3% modulation).
