Nonin Medical’s WristOx2 Model 3150 offers oxygen saturation and pulse rate monitoring for patients in home and hospital settings.
RT’s Three Key Takeaways:
- Clinical Versatility: The device is intended for oxygen qualification, six-minute walk tests, and pulmonary rehabilitation in both home and hospital environments.
- Data Storage and Verification: The oximeter features 1,080 hours of memory and a graphic display mode to confirm that sufficient data has been recorded for clinical testing.
- Performance in Motion: A pulse-by-pulse averaging algorithm allows for accurate oxygen saturation and pulse rate readings during motion and low perfusion.
Nonin Medical’s WristOx2 Model 3150 provides oxygen saturation and pulse rate readings for various clinical applications, including pulmonary rehabilitation and sleep screening. The device is designed to maintain accuracy during motion and low perfusion, according to product specifications from Nonin Medical.
The wrist-worn oximeter is compatible with PureLight sensors and is used for oxygen qualification, six-minute walk tests (6MWT), and pulmonary rehabilitation conducted in home and hospital settings. For homecare use, the device supports overnight sleep apnea screening and clinician-directed oxygen qualification, according to the company.
The Model 3150 features 1,080 hours of non-volatile memory at a four-second sampling rate, with additional high-resolution options of one or two seconds. It operates for 48 hours on two AAA batteries and includes a Memory Volume Indicator (MVI) mode. This mode provides a graphic display in hours and minutes to verify that a sufficient amount of data was recorded during testing.
In a hypoxia testing case study, the WristOx2 Model 3150 accurately measured 20 out of 21 desaturation events, representing a 95.2% accuracy rate, according to data from Nonin Medical. The device utilizes a pulse-by-pulse averaging algorithm that adjusts to a patient’s condition to provide precision accuracy.
Overnight pulse oximetry is also utilized to evaluate the response to oral appliance therapy (OAT) during treatment for obstructive sleep apnea (OSA). Monitoring a patient’s heart rate and blood oxygen saturation is essential in pre-confirming the effectiveness of these therapies, according to a company white paper.
The device is designed to wear like a watch and includes a large display screen and an enhanced sensor connector. Single-use accessories are also available to limit exposure to infectious agents, according to the company. Data can be transferred to nVISION data management software via a USB connection for overnight reporting.
