日常生活中经常看到父亲睡觉时鼾声如雷。儿子虽然年纪小，但鼾声不逊于父亲。在其他家庭中，几代人都遭受过打鼾和夜间睡眠呼吸暂停，甚至发生过夜间猝死。打鼾和睡眠呼吸暂停确实和遗传有关Medris迈睿思吸氧机浓度上不去维修点。

　　从目前的研究情况来看，虽然尚不清楚打鼾是如何遗传的，但国内外流行病学调查和研究均证实睡眠呼吸暂停综合征具有明显的家族聚集性Medris迈睿思吸氧机浓度上不去维修点。1988年，研究人员调查了4000对芬兰双胞胎，发现遗传因素相似的同卵双胞胎打鼾的符合率远高于同卵双胞胎。1991年美国的一项调查发现，睡眠呼吸暂停综合征患者的直系亲属打鼾、白天嗜睡和呼吸暂停的发生率比正常对照者的直系亲属高2-4倍。进一步研究表明，打鼾和睡眠呼吸暂停综合征的发生确实与遗传密切相关Medris迈睿思吸氧机浓度上不去维修点。日本研究人员发现，人类白细胞表面的特殊抗原HLA-A2与睡眠呼吸暂停综合征的发病率高度相关， which is a possible genetic basis for causing sleep apnea syndrome.Medris迈睿思吸氧机浓度上不去维修点

　　Snoring has family aggregation, and the decrease of brain's ability to drive breathing during sleep is one of the reasons leading to sleep apnea. People whose respiratory center has low response to hypoxia and hypercapnia are more likely to have sleep apnea, and patients can't wake up in time after apnea, so it is difficult to restore airflow as soon as possibleMedris迈睿思吸氧机浓度上不去维修点. That is to say, the duration and frequency of sleep apnea increase in people with low respiratory drive function. The central respiratory drive function is influenced by genetic factors. It has been reported that nine people in a family of three generations suffer from sleep apnea syndrome. The respiratory drive function of five of them was measured, and it was found that all of them had low response to hypoxia stimulation, which indicated that they all had central respiratory control function defects.
