The Nonin Onyx Vantage 9590 is a handheld finger pulse oximeter that measures your functional oxygen saturation (SpO2) and pulse rate. Place it on a fingertip, and it shows a reading in seconds, with no wires, no setup, and no waiting.
Who it is for
It suits anyone who wants to check their oxygen levels at home between appointments, including people managing a respiratory or sleep condition and the caregivers who help them. Because it fits both adult and paediatric fingers, from 8 to 25.4 mm, one device works for most of a household.
Accurate across skin tones
Optical oximeter readings can be affected by skin pigmentation, which sits in the light path, so accuracy across skin tones matters. Nonin’s PureSAT technology reads SpO2 and pulse rate quickly, including across a range of skin tones and when circulation to the fingers is low.

Do you need a prescription?
A pulse oximeter is a monitoring device, so no prescription is required. You can order it and have it shipped anywhere in Canada. A pulse oximeter is a spot-check monitor rather than oxygen therapy. If you use supplemental oxygen, you can browse our oxygen concentrators and other home monitoring and CPAP accessories, and our oxygen therapy resources explain how prescriptions work in Canada.
Questions about the Onyx Vantage?
A pulse oximeter is a check-in tool, not a diagnosis. If your readings are consistently lower than usual, or you feel short of breath, contact your healthcare provider. If you have questions about whether the Onyx Vantage fits your needs, our Canadian team is happy to help.
