Obstructive sleep apnea and hypopnea syndrome (OSAHS) is a disorder that causes clinical symptoms (e.g. snoring, excessive daytime sleepiness and impaired concentration) that may increase the risk of traffic accidents, cardiovascular disease, type 2 diabetes and reduce the quality of life. A recently developed device (Somnolter®) detects apneas and hypopneas in a home setting, allowing to detect OSAHS in a more comfortable environment compared to the gold standard polysomnography. The aim of our study was to investigate whether the Somnolter® is useful in family practice to identify patients with OSAHS.
Questionnaires were offered to patients in five general practitioner (GP) practices.Based on the questionnaire and body mass index, patients with an increased risk of OSAHS were contacted to collaborate in the study. In this convenience sample, 18 patients were successfully tested with the Somnolter® measuring SaO2, mandibular movements, body position, heart rate, nasal air flow and thoracic and abdominal breathing movements. The Somnolter® automatically analyses the data and different parameters to detect OSAHS. Afterwards, the data were manually revised by the researchers.
Out of 365 subjects, 31 met the inclusion criteria and 18 were successfully tested at home. Sixteen out of 18 patients had an Apnea Hypopnea Index (AHI) ≥ 5, ten of them had mild OSAHS, 3 were categorized as moderate OSAHS and finally 3 matched the criteria of severe OSAHS.
The proposed case-finding strategy still needs optimization, but is considered helpful in selecting patients at high risk of OSAHS. OSAHS was detected in 14 out of 18 patients tested with the Somnolter®. In the future the Somnolter® might be a feasible alternative to diagnose OSAHS.
阻塞性睡眠呼吸暂停低通气综合征（OSAHS）是一种引发临床症状（如打鼾、日间过度嗜睡和注意力不集中）的疾病，这些症状可能会增加交通事故、心血管疾病、2型糖尿病的风险，并降低生活质量。一种最近研发的设备（Somnolter®）可在家庭环境中检测呼吸暂停和低通气，与金标准多导睡眠图相比，能在更舒适的环境中检测OSAHS。我们研究的目的是调查Somnolter®在家庭医疗中对识别OSAHS患者是否有用。
向五家全科医生（GP）诊所的患者发放问卷。根据问卷和体重指数，联系有OSAHS风险增加的患者参与研究。在这个便利样本中，18名患者成功使用Somnolter®进行了测试，该设备可测量血氧饱和度（SaO2）、下颌运动、身体位置、心率、鼻气流以及胸廓和腹部呼吸运动。Somnolter®会自动分析数据和不同参数以检测OSAHS。之后，研究人员对数据进行人工核对。
在365名受试者中，31名符合纳入标准，18名在家中成功进行了测试。18名患者中有16名的呼吸暂停低通气指数（AHI）≥5，其中10名患有轻度OSAHS，3名被归类为中度OSAHS，最后3名符合重度OSAHS的标准。
所提出的病例发现策略仍需优化，但被认为有助于筛选出OSAHS高风险患者。使用Somnolter®测试的18名患者中有14名检测出患有OSAHS。未来，Somnolter®可能是诊断OSAHS的一种可行替代方法。
