This equipment complies with International Standard IEC 60601-1-2 for electromagnetic compatibility for medical electrical equipment and/or systems. This standard is designed to provide reasonable protection against harmful interference in a typical installation. However, because of the proliferation of radio frequency transmitting equipment and other sources of electrical noise in health care, home, and many other environments, it is possible that high levels of such interference due to close proximity or strength of a source might disrupt the performance of this device.
This product complies with ISO 10993-1, Biological evaluation of medical devices – Part 1: Evaluation and
Frequently Asked Questions
What’s the difference between GO2 and GO2 Achieve?
The Nonin GO2 finger pulse oximeter for personal use is a medical device; federal law restricts these devices to sale by or on the prescription order of a licensed clinician. GO2 is not intended for diagnosis, treatment, cure, or prevention of any chronic lung or other disease. You need a prescription oximeter if you are a patient working with a doctor and need to monitor blood oxygen saturation for a chronic disease such as COPD.
The Nonin GO2 Achieve is not a medical device and therefore does not require a prescription from your doctor. You can use a GO2 Achieve non-prescription oximeter if you are a sports or fitness enthusiast interested in managing your intensity level while exercising or training. A non-prescription oximeter can also be used to check for the onset of in-flight hypoxia during air travel. GO2 Achieve provides fast and accurate pulse rate and blood oxygen saturation data.
What is included in the purchase price of the GO2?
Each GO2 contains one AAA battery and an instruction booklet.
Can this unit be used on adults and pediatrics?
It is intended for home health care use on adult or pediatric patients with a finger thickness between 0.3 – 1.0 in. (0.8 – 2.5 cm).
Is the GO2 as accurate as other Nonin fingertip devices?
Yes. The proven SpO2 accuracy for the 9570 is +/- 2 digits; pulse rate accuracy +/-
How long can I wear this unit?
The GO2 is not recommended where motion is expected, or for relatively long-term
monitoring (e.g. more than 30 minutes).
Where does the unit take a reading?
It is designed for use on fingers (other than the thumb). The index finger is the recommended site.
How do I turn my GO2 on and off?
The GO<sub>2</sub> automatically turns on when a finger is inserted; after you’re done taking
your reading, remove your finger and the unit will shut off in approximately 10 seconds.
How do you know you’re getting an accurate reading?
The pulse quality indicator (♥) displays pulse rate signal strength. Bars displayed after the ♥ indicate pulse signal strength (♥♥♥♥); more bars indicates greater pulse quality signal strength.
What does this symbol Ǿ mean?
This symbol indicates that there isn’t sufficient pulse strength to make an accurate measurement, or lights when finger is removed from unit.
Will I be able to use my GO2 in a dark room?
Yes. The unit has a backlit display, which includes a sensing circuit to determine when illumination is required; this reduces unnecessary battery drain.
When I enter a darker room while taking a measurement, the display doesn’t light up. Why?
When the unit is powered up, it checks to see if there is sufficient light and determines if the display should be illuminated. For the display to light up in a darker room, the unit has to be powered off and back on.
What is the typical battery usage?
One 1.5 volt AAA-size batteries power the GO2 for about 2,400 spot checks or 21 hours of continuous operation.
How does the unit display low batteries?
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
How do you replace the batteries?
- Remove the battery door located on the left side of the GO2 by sliding it toward you.
- Insert one new 1.5 volt AAA battery. Follow the plus (+) and minus (-) markings for battery direction (as shown inside the battery compartment).
- Carefully reposition the battery door.
