The Nonin WristOx2 3150 USB is a wrist-worn pulse oximeter that records up to 1,080 hours of oximetry for ambulatory and overnight studies. It weighs just 2.5 ounces on the wrist and downloads by USB, so patients can wear it for days while the data stays secure in non-volatile memory.
- Up to 1,080 hours of non-volatile memory at a 4 second sampling rate
- Variable sampling at 1, 2 or 4 seconds captures rapid saturation changes
- Only 2.5 ounces with batteries and wrist band for multi day wear
- USB download with nVISION software compatibility
WristOx2 3150 USB Wrist-Worn Oximetry for Ambulatory and Sleep Studies
Overnight oximetry and ambulatory assessment need a recorder patients will actually keep wearing, and this wrist-worn unit was designed around that compliance problem. At 2.5 ounces with batteries and its wrist band, the device stays unobtrusive through sleep, exercise testing and daily activity. Memory capacity reaches 1,080 hours at a four second sampling rate, with one and two second rates available when a study needs finer resolution. PureSAT processing maintains accuracy in motion, which matters for stress applications such as the six minute walk test. Data downloads over USB for analysis in nVISION, and the non-volatile memory keeps recorded studies safe even if battery power is lost. Configurations range from a device only assembly to complete kits with each of the five PureLight WO2 sensor types.
