一種設(shè)計(jì)用來(lái)幫助分析睡眠相關(guān)呼吸紊亂的腕帶式設(shè)備，現(xiàn)在擴(kuò)大了其用途。美國(guó)食品藥品管理局已經(jīng)批準(zhǔn)這種設(shè)備做為檢查快速動(dòng)眼運(yùn)動(dòng)睡眠時(shí)相的診斷輔助工具。

在這項(xiàng)批準(zhǔn)之前，檢查REM睡眠時(shí)相的唯一途徑是在實(shí)驗(yàn)室內(nèi)整夜多導(dǎo)睡眠描計(jì)研究。使用Watch-PAT(外周動(dòng)脈張力測(cè)定法），研究人員發(fā)現(xiàn)這套設(shè)備能夠預(yù)測(cè)REM睡眠，接近實(shí)驗(yàn)室睡眠評(píng)估的金標(biāo)準(zhǔn)。Watch-PAT提供了低成本選擇，擴(kuò)大了在家庭或者醫(yī)院內(nèi)的診斷檢測(cè)能力。

REM檢查是評(píng)估睡眠紊亂的關(guān)鍵部分，但是很難進(jìn)行檢查，如果不使用腦電圖、心電圖、眼動(dòng)電圖的電極粘貼在患者頭部和胸部。

Brigham和婦女醫(yī)院（波士頓，美國(guó)）的睡眠疾病項(xiàng)目主任、哈佛大學(xué)醫(yī)學(xué)院睡眠醫(yī)學(xué)教授David P.White醫(yī)生說(shuō)：“REM睡眠檢查對(duì)于診斷睡眠紊亂十分重要，是評(píng)估睡眠質(zhì)量和患者對(duì)睡眠呼吸暫停治療反應(yīng)的關(guān)鍵因素。”

Watch-PAT是由Technion以色列技術(shù)學(xué)院(Haifa, Israel)研究人員研制成功的，在哈佛醫(yī)學(xué)院附屬睡眠中心以及其它中心進(jìn)行了檢測(cè)。Watch-PAT以及其它PAT產(chǎn)品已經(jīng)由Itamar醫(yī)學(xué)有限公司(Caesarea, Israel)推向了市場(chǎng)。
 
Device Monitors REM Sleep

A wrist-worn device designed to aid the analysis of sleep-related breathing disorders now has expanded indications. The U.S. Food and Drug Administration (FDA) has cleared the device as a diagnostic aid for the detection of rapid-eye movement (REM) sleep stages.

Before this approval, the only way to detect REM-sleep stages was with an in-lab overnight polysomnographic study. Using Watch-PAT (peripheral arterial tonometry), researchers showed that the device was predictive of REM sleep and was close to the gold standard in sleep lab evaluation. Watch-PAT offers a lower-cost option that can expand the availability of diagnostic testing at home or in the hospital.

REM detection is a critical component of the evaluation of sleep disorders, but has been difficult to measure without the use of an electroencephalogram (EEG), electrocardiogram (ECG), and electrooculogram (EOG) electrodes attached to the patient’s head and chest.

“REM sleep detection is important for proper sleep disorder diagnosis and a critical factor in the evaluation of sleep quality and patient responses to the treatment of sleep apnea,” stated David P. White, M.D., professor of sleep medicine at Harvard University School of Medicine and director, sleep disorders program at Brigham and Women’s Hospital (Boston, USA).

Watch-PAT was developed by researchers at the Technion Israel Institute of Technology (Haifa, Israel), and was studied at sleep centers affiliated with Harvard Medical School and other centers. The Watch-PAT and other PAT products are being marketed by Itamar Medical Ltd. (Caesarea, Israel).
