人在睡眠时可发生各种现象,最常见莫过于睡眠时打鼾,俗称打“呼噜”。对这种现象,多数人认为是一种“正常”睡眠的现象,是睡得“香甜”,或者是一种“熟睡”、“深睡”的表现,没有人认为这也是一种“病”。打鼾者对晨醒后感觉身体的不舒服,如口干舌燥、咽部不适、醒后仍不解乏、没精神,甚至头痛和白天嗜睡、记忆力下降、血压增高等症状,没有与睡眠时打鼾联系起来,使打鼾引起的各种病症得不到及时合理的治疗,经常被误诊或漏诊。 “打鼾”也是病,打鼾代表了睡眠时呼吸道的一种不通畅。正像气流通过一个管道系统,当气流不变时,气流通过的管道愈细,则气流的阻力愈大,作用于管壁的摩擦和震动力也愈大。如果管道直径小到气流通过时发出的一种声响,那么,就会像是吹哨子所发出的声音一样。睡眠时“打鼾”是呼吸气流通过狭窄气道阻力增高,引起咽腔周围组织的震动,伴随呼吸的节律活动而形成的一种“鼾声”。这种现象仅发生在睡眠时,而不发生在醒觉
People can occur during sleep a variety of phenomena, the most common than sleep snoring, commonly known as playing “snore.” To this kind of phenomenon, most people think it is a “normal” sleep phenomenon, it is “sweet” to sleep, or a performance of “deep sleep” and “deep sleep.” No one thinks this is a kind of “sickness” . Snorers feel uncomfortable after morning wake, such as dry mouth, throat discomfort, wake up still not tired, no energy, and even headache and daytime drowsiness, memory loss, high blood pressure and other symptoms, there is no sleep with snoring Linked to the various causes of snoring caused by timely and reasonable treatment, often misdiagnosed or missed. “Snoring” is also a disease, snoring represents an unobstructed airway during sleep. Just as the airflow passes through a pipe system, the finer the pipe through which the airflow passes when the airflow is constant, the greater the airflow resistance and the greater the friction and shock forces acting on the pipe wall. If the diameter of the pipe is as small as the sound of a whistle, it will sound like a whistle. Sleep, “snoring” is a respiratory flow through the narrow airway resistance increased, causing the vibration around the pharynx tissue, accompanied by respiratory rhythmic activity and the formation of a “snoring.” This phenomenon occurs only in sleep, but not in wake
