Background technology
Obstruction sleep apnea-hypopnea syndrome (OSAHS) is a kind of very common disease, is characterized in sleeping
During dormancy, epithelium healing partly or entirely subsides, and causes related disordered breathing of sleeping.Serious OSAHS can cause serious danger
Evil：Cardia cevent, drowsiness, the carbohydrate metabolism disturbance on daytime, or even asphyxia.The OSAHS prevalences of external report are 2%～
4%, and all increase with the age.Domestic data shows：Hongkong (30～60 years old) prevalence male is 4.1%, Nv Xingwei
2.1%.Shanghai (＞ 30 years old) prevalence is 3.6%, estimates OSAHS patient at least 2000 of China's age more than 30 years old accordingly
Ten thousand.
Clear and definite OSAHS is the independent hazard factor for causing hypertension outside the factors such as obesity, heredity, smoking at present.OSAHS
Dependency relation is not only existed between hypertension, and is cause effect relation.During epidemiological study result shows hyperpietic
OSAHS prevalences about 30%～50%, in OSAHS patient, Prevalence of Hypertension is 50%～80%, high blood in population
Pressure prevalence is usually 10%～20%.Refractory hypertension, simple medication effect mostly are by the hypertension that OSAHS causes
Difference.Satisfied effect can be received if taking correct therapeutic strategy (Drug therapy+CPAP etc.).Common hyperpietic is (i.e. non-
OSAHS causers) belong to Wood-scoop type more, and by, in the hyperpietic that causes of moderate or severe OSAHS the non-Wood-scoop type of 69.4% category.First, blood
Pressure rising mostly occurred in night and early morning, is difficult to find its dysarteriotony if do not carried out 24 hours monitoring of blood pressure, thus has hidden
The property hidden, is difficult early discovery.Second, easily there is left ventricular hypertrophy in Non-dipper hypertension, and Diastole Function goes down.Its disease
4.5 times for dipper hypertension of dead rate.
One investigation of Japan finds that the Relative hazard that OSAHS patient suffers from ischemic heart desease (IHD) is general population's
1.2～6.9 times, AHI >=10 time of 35%～40%IHD patients/hour, 23.8% OSHAS patient suffers from IHD simultaneously.Weight
In degree OSAHS patient, 50% suffers from coronary heart disease, and nearly 30% OSAHS patient occurs myocardial ischemia during nighttime sleep, especially
Which is in REM sleep phase.The results of study such as Peker P show that the patient with OSAHS dies from myocardium stalk during follow-up in 5 years
(without OSAHS, 9.3%) probability (37.5%) of dead and apoplexy is significantly higher than matched group.There is mistake aroused in interest in 80%OSAHS patient
Slow, ventricular premature contraction incidence rate is 57%～74%.More than 10% patient can occur II Aminophyline.Work as SaO2<60%
When may occur in which frequently premature beat.56.2% generation arrhythmia in 146 OSAHS patients, including morning are reported according to Concord Hospital
Fight, tachycardia, atrioventricular block etc..CHF patient 40%～60% merges sleep disordered breathing.Predominantly central sleep
Asphyxia.
OSAHS is in close relations with diabetes, especially relevant with insulin resistant, after the treatment OSAHS that adopts an effective measure,
Diabeticss Insulin Curative is obviously improved, it is thus regarded that OSAHS is probably the main cause for causing insulin resistant.
OSAHS is also asymptomatic albuminuria high risk factor, particularly with hypertension and the crowd of diabetes.

Art formula：Uvulopalatopharyngoplasty (Uvulopalato-pharyngoplasty, UPPP) and its improvement operation are usually used in upper gas
Road pars oralis pharyngises obstruction (include pharyngeal mucosa tissue is plump, pharyngeal cavity is narrow and small, uvula is loose, soft palate is too low, hypertrophy of tonsils) and
And 20 time/hour persons of AHI ＜.But postoperative easy recurrence, and wound is larger, spends higher.Appliance is usually used in simple snore
Disease and slight OSAHS patient's (15 times/hour of AHI ＜), the person that particularly has mandibular retrusion.For not being resistant to CPAP, it is impossible to
Operation or surgical effect gastrointestinal disease patient can be tried out, but effectiveness is relatively low.Continuous positive airway (Continuous
Positive airway pressure, CPAP) a physiological stress support epithelium healing can be provided, it is ensured that epithelium healing during sleep
Opening.But which has a disadvantage that：
It is expensive, popularization is difficult in developing country use；
Equipment instrument is larger, it has not been convenient to carry, especially inconvenient for the personage for often going on business；
3rd, connecting line limits patient at night activity, and compliance is reduced；
4th, continuous positive pressure means that continuous flow is present, and can cause Most patients sense of discomfort, so that considerable trouble
Person is not resistant to treatment；
5th, it is poor to central sleep apnea patient therapeutic effect.
