Weixin Official Accounts Platform Shanghai Sixth People’s Hospital and Tsinghua University jointly publish a paper: Millimeter-wave radar technology aids in the diagnosis of sleep apnea. Original TsingRay Technology TsingRay Technology TsingRay Technology Beijing TsingRay Technology Co., Ltd. TsingRay Technology is a national high-tech enterprise for the transformation of scientific and technological achievements of Tsinghua University, a specialized and new small and medium-sized enterprise in Beijing. The company, based on 20 years of technological accumulation of Tsinghua University, conducts medical-engineering interdisciplinary research, clinical validation, and product development. The developed medical-grade millimeter-wave radar products are widely used in disease diagnosis, chronic disease management, health monitoring, smart elderly care, and other scenarios. 178 original content September 20, 2024 17:55 Beijing Recently, the Chinese Journal of Otorhinolaryngology Head and Neck Surgery published a paper titled ‘Diagnosis of Obstructive Sleep Apnea by a New Radar Device: A Parallel Controlled Study Evaluating Equivalence with Polysomnographic Monitoring.’ The study was jointly completed by the team of Yin Shankai, president of Shanghai Sixth People’s Hospital, and Li Gang, professor of the Department of Electronic Engineering of Tsinghua University and chief scientist of TsingRay Technology, and his team. It aims to study the equivalence of the low-load sleep monitoring system QSA600 developed by TsingRay Technology and the traditional PSG polysomnographic monitoring equipment in diagnosing obstructive sleep apnea (OSA). The results showed: ‘As a low-load new sleep monitoring system, QSA600 shows very high consistency with PSG in diagnosing OSA and different severity levels of OSA, and has good clinical application prospects.’ Screenshot of the paper. The study recruited a total of 155 subjects from July to September 2023 for the parallel control trial of QSA600 and PSG in the sleep laboratory of the Department of Otorhinolaryngology Head and Neck Surgery of Shanghai Sixth People’s Hospital. The study used the key diagnostic indicator of obstructive sleep apnea, the apnea-hypopnea index (AHI), as the main comparative data for analysis. Shanghai Six Hospital GCP trial site. The results showed that, with AHI thresholds of 5 times/h, 15 times/h, and 30 times/h, the sensitivity for diagnosing mild, moderate, and severe OSA was 88.68%, 89.83%, and 97.06%, respectively, and the specificity was 94.87%, 98.84%, and 99.10%, respectively. The area under the receiver-operating characteristic (ROC) curve was 0.9734, 0.9909, and 0.9995, respectively. The Pearson correlation between the two was 0.9872 (P
