Nonin WristOx2 3150 BLE - Wrist pulse oximeter for overnight oximetry

Why measure your oxygen when you are already on CPAP

A CPAP corrects apnoeas, and that is what it measures. It does not measure your oxygen. Yet desaturations can persist despite a well followed therapy, for reasons other than obstruction. A reassuring apnoea index therefore does not tell the whole story.

Overnight oximetry fills that gap. You wear the device on your wrist and its sensor on your finger and you sleep with your CPAP as usual. In the morning you have a full curve of your saturation. That is something concrete to bring to your appointment.

How it works in practice

• You put it on at bedtime: the unit goes on the wrist like a watch, the sensor clips onto a finger. Nothing to set, nothing to start on your CPAP
• It records on its own: saturation and pulse, all night, in non-volatile memory. Changing the batteries does not lose the data already recorded
• You get the report: by USB cable into the nVISION software on a computer, or over Bluetooth to the Nonin Health platform

Which CPAP it works with

Who it is for

For those who want to understand what happens at night rather than rely on the single index the machine shows. And for those whose doctor asks for a control oximetry without wanting a full laboratory recording again.
