Clinical Validation
ARESTM Clinical Validation and Other Studies
Better Sleep Starts Here
Watermark Medical is unique in that we provide excellent Home Sleep Testing – the ARESTM system, which has been peer-reviewed and tested by several major medical publications.
The accuracy of ARESTM has been validated by several studies done under controlled laboratory settings, as well as unattended environments. The system has demonstrated a strong concordance with simultaneously collected PSG.
Our program is part of a comprehensive approach to sleep medicine. It is designed to be used in conjunction with our validated ARESTM Obstructive Sleep Apnea (OSA) questionnaire.
A Clinical Application
The ARESTM device is comfortable to wear, accessible, and user-friendly, making it easier than ever to gather critical information about patient sleep cycles. Our device is capable of accumulating up to three days of data. This provides comprehensive analytics to facilitate OSA diagnosis and measure the severity of the condition. From there, referred specialists within our network can provide patients with proper treatment.
Research Solutions
For over a decade, pharmaceutical, medical device companies, and research clinicians have turned to us for research services, diagnostics, and therapeutic testing in the validation process, which precedes FDA approval. Watermark Medical prides itself in conducting clinical research and database science research to demonstrate the clinical elements of the ARESTM device. Our history of in-depth clinical studies and white papers supporting the effectiveness of our device include the following:

ARESTM questionnaire performs better than the Berlin questionnaire
The ARESTM questionnaire performed better than the Berlin questionnaire with higher sensitivity but lower specificity.
Validation study of a portable monitoring device for identifying OSA in a symptomatic patient population
One hundred forty-one patients wore ARESTM while undergoing a PSG study. Results of AHI from the ARESTM study were presented in the order of different scoring criteria – 4% oxygen desaturation alone, obstructive events with 1% desaturation plus surrogate arousal criteria. The sensitivity was 0.84 (95% confidence interval (CI): 0.77-0.90) and 0.97 (95% CI: 0.94-0.99), respectively. The specificity was 1, and 0.63 (95% CI: 0.55-0.71), respectively. The receiver operating curve had an area of 0.96 and 0.98, respectively. The ARESTM device has reasonable sensitivity and specificity for diagnosing severe OSAS in symptomatic Chinese patients.
The correlations between the ARESTM and PSG
The relationships between the ARES™and PSG for simultaneously acquired recordings was 0.96 using an apnea/hypopnea index with a 4% desaturation (AHI-4%), and 0.93 using a respiratory disturbance index based on Chicago criteria (RDI). The diagnostic sensitivity of in-lab ARES™ RDI was 0.95, and the specificity was 0.94; comparable measures to PSG for the in-home ARESTM RDI values were 0.85 and 0.91.
