Product info

The O2Ring has been replaced by the O2Ring S, its new generation: one reading per second in the reports instead of four, and 24 hours of battery instead of 12 to 16.

For obvious hygiene reasons, any item that has been unboxed and/or used cannot be returned or exchanged.

ℹ️ For more info, please see our terms and conditions of sale.

The O2Ring has made way for the O2Ring S

The O2Ring made overnight finger oximetry popular: a ring worn while you sleep that records oxygen saturation and pulse, and vibrates if either goes outside the thresholds you set. The manufacturer has replaced it with the O2Ring S, and that is the one we offer.

What the S version brings

  • One-second reports, instead of one point every four seconds
  • 24 hours of battery, instead of 12 to 16 hours
  • USB-C charging, and one adjustable size in soft silicone

Excellent experience — reliable shop and great customer service

I am very satisfied with my experience with VivaRespire. There was a small delay due to a supply issue on the manufacturer’s side, but Andy was very kind, professional and quick to respond. He explained the situation transparently and kept me informed throughout the process.
My order eventually arrived exactly as requested, with everything in perfect condition. The prices are excellent, the products are high quality, and the customer service is genuinely helpful and reliable.
I would definitely recommend VivaRespire to anyone looking for CPAP equipment and accessories.
