Diagnosing obstructive sleep apnea (OSA) typically has required an overnight stay in a hospital or clinic sleep lab. However, many patients are either unwilling to go to a sleep lab or find it difficult to reach natural sleep in that setting, resulting in variable or inconclusive test results. Home sleep tests are a clinically accurate and cost-effective alternative.

The NovaSom® Diagnostic System, from Sleep Solutions, Inc., has been cleared by the FDA for diagnostic evaluation of adults with possible sleep apnea. The NovaSom home sleep test is covered by Medicare and a growing list of insurance plans; in fact, healthcare contracts for the NovaSom system now cover more than 160 million individuals.

The system consists of a compact bedside console and three sensors that are easily applied by the patient. It uses voice prompts to talk the patient through its set-up and operation. During sleep, NovaSom utilizes patented audio digital signal processing technology to sense, analyze, and process a patient’s respiratory sounds and convert the sounds into airflow volume.

Once prescribed by a physician, NovaSom is delivered directly to the patient’s home. The patient uses the diagnostic device for 3 consecutive nights, collecting sleep data such as respiratory events (apneas and hypopneas), snoring intensity, blood oxygen saturation, pulse rate, and respiratory effort.

After 3 nights of use, the NovaSom Diagnostic System is returned via prepaid overnight shipping to Sleep Solutions, where the patient’s test data are analyzed, downloaded, and sent to a qualified physician for interpretation and diagnosis. Study results are delivered to the referring physician within 48 hours of receipt from the patient. This allows for rapid and accurate diagnosis of OSA and appropriate treatment recommendations. In clinical studies, diagnostic accuracy and predictability of the system were proven to be comparable to in-lab polysomnography for diagnosis of OSA, at a fraction of the cost.
