There are seemingly countless gadgets and apps to help monitor your health nowadays, but few can offer the kind of detail that Masimo's iSpO2 pulse oximeter can. The California-based company's latest release, on display here at CES, is a small plastic device that can non-invasively measure a user's blood oxygen levels and pulse rate. All you have to do is attach the dongle to your iOS device, slip the white plastic sensor over your finger, and let the oximeter measure your vitals, which it does by beaming infrared lights at the tip of your digit.

The iSpO2 certainly isn't the only consumer-level oximeter on the market today, but it is the first to offer iOS compatibility, collecting a user's data and health metrics in a single app (available for free on the App Store). The device has yet to receive FDA approval, meaning it can't be explicitly used for medical purposes, though Masimo seems confident that it will in the near future. In the meantime, the company is marketing it to mountain climbers and aviators, who may need to monitor their oxygen levels at higher elevations.

The iSpO2 is currently available for $250. At this point, it's only compatible with iOS, though the company says it should be releasing an app for Android in the near future.
