When buying a pulse oximeter to pre-screen for OSA and verify the effectiveness of OAT, look for an accurate, easy-to-use, cost-effective device
What costs more – multiple sleep tests to find out if the therapy is working or missing the problem altogether? There may be no clear answer, but there is a product that helps the sleep dentist with both of these expensive problems.
Continuous positive airway pressure (CPAP), the treatment of choice of most physicians, is unfortunately abandoned by more than half of all patients within a year due to discomfort.1 Oral appliance therapy (OAT) is often deployed by dentists working with referring sleep physicians. Studies have shown that patients are more compliant with OAT than with CPAP,2 but the mandibular advancement devices do not have a performance or compliance smartcard. The physicians and the dentists need to know whether the airway problem is being solved. Repeat PSG? Not covered. HST? Patients may find them complicated and unreliable.
Overnight pulse oximetry monitoring is essential in pre-confirming the effectiveness of OAT for treating OSA
The American Academy of Sleep Medicine / American Academy of Dental Sleep Medicine 2015 guidelines recommend oral appliances as a first line treatment option for many OSA patients.3 According to the AADSM and the AASM, overnight pulse oximetry has been shown to be an effective sleep screening tool used to evaluate the response to OAT prior to sending patients back for follow-up polysomnography (PSG) testing at a sleep lab.4
Pulse oximeters are noninvasive medical devices used for measuring pulse rate and blood oxygen saturation (SpO2). There are many FDA-cleared brands on the market, but it’s important to understand that not all FDA-cleared pulse oximeters and sensors perform alike. Accurate readings are crucial to avoid missing desaturation events or having to repeat sleep studies.
Obtain Reliable SpO2 Results the First Time
Engineered with proven PureSAT® SpO2 technology, Nonin Medical’s WristOx2® Model 3150 wrist-worn pulse oximeter provides accurate, continuous oxygen saturation and pulse rate monitoring during overnight sleep studies. Nonin PureSAT SpO2 technology is clinically proven accurate in the most challenging patients and settings – even in patients with poor circulation or dark skin, or with excessive motion.5 It’s little surprise, then, that 90% of PSG manufacturers use Nonin pulse oximetry!
Designed for pediatric and adult patients, the WristOx2 is comfortable to wear and easy to use. Patients simply attach the WristOx2 like a watch, put their finger in the soft sensor and go to sleep. The device turns on automatically when a finger is inserted and turns off when the finger is removed.
And the best part? Dental sleep practitioners save valuable training time and minimize the risk of patient set-up errors by pre-programming the device before it goes home with patients.
The WristOx2 is rugged (it’s manufactured and serviced in the USA) and efficient (it provides up to 48 hours of continuous use on two AAA batteries), so clinicians can spend more time treating their patients and less time worrying about device maintenance and repairs.
And when it’s time to analyze the data, Nonin’s nVISION® data management software provides simple viewing, reporting and patient file storage.
