Information for Physicians

The ARES is one of the easiest to use home sleep testing devices in the market. It’s simple design and comfortable application leads to more compliance and better results. The process for this test is to have the patient’s primary care physician screen patients for sleep abnormalities during their routine visits.  When abnormalities are found, the physician will dispense a take home device that they have available in their office's.  The patient will take the device home, wear it that evening while they sleep, and return it to the physician office the next day.  Results will be available usually within 24 hours. 


Based on the results, the physician can:


a) rule out OSA

b) diagnose OSA and prescribe therapy or

c) prescribe further testing or titration to be performed in a sleep laboratory using PSG.  Prior to the home sleep test, only option 3 was available to primary care physicians at the expense and inconvenience of millions of patients.


Home Sleep Tests (HST) usually monitor anywhere from 4 to 9 channels of data for the physician.  ARES Unicorder measures blood oxygen saturation (SpO2) and pulse rate (reflectance pulse oximetry), airflow (by nasal cannula connected to a pressure transducer), snoring levels (calibrated acoustic microphone), head movement and head position (accelerometers). Some HST devices (like the ARES) are sophisticated enough to include EEG, EOG, and EMG making it clinically comparable to a laboratory PSG.


Diagnosing and Treating Sleep Apnea


Medical providers and health insurance companies have finally realized that early detection is more cost-effective and conveniently manageable than the deadly consequences of apnea-related diseases such as obesity, hypertension, heart failure, stroke, sexual dysfunction, and depression. The home-based diagnosis and treatment of Sleep Apnea is a growing and vital field.
