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.
