舒张压

• This pressure is usually described in terms of millimeter mercury mmhg . the pressure recorded during contraction of heart is called " systolic blood pressure " , and the pressure recorded during relaxation of heart is called " diastolic blood pressure "
  通常量度压力是以毫米水银柱mmhg为单位，心脏收缩时的压力叫收缩压，通常是120 mmhg左右，心脏舒张时的压力叫舒张压，通常是80 mmhg左右，记录如下120 80 mmhg 。
• Methods : divided 150 hypertension patients into three groups : 52 diastolic blood pressure patients ; 15 isolated systolic hypertension patients ; 54 patients of systolic blood pressure and diastolic blood pressure and cardio - cerebrovascular diseases and had clinical analysis on them
  方法：将150例高血压患者分成3组： 52例舒张压升高患者； 15例单纯收缩期高血压； 54例收缩期、舒张期均高的高血压并发心脑血管病发症的患者进行临床分析。
• Systolic and diastolic blood pressures clustered together with leptin in the factor analysis and this blood pressure - adiposity component correlated with estimated creatinine clearance ( r = 0 . 329 , p < 0 . 0001 ) and explained on its own 10 . 2 % of the variance in the estimated renal function
  在析因分析中发现收缩压和舒张压与瘦素相关联，这种血压?肥胖组合与估算的肌酐清除率具有相关性（相关系数0 . 329 , p < 0 . 0001 ） ，其本身可以造成10 . 2 %的肾功能变化。
• The pressure recorded during contraction of heart is called " systolic blood pressure " ( sbp ) , and the pressure recorded during relaxation of heart is called " diastolic blood pressure " ( dbp ) . sbp is usually around 120 mmhg and dbp around 80 mmhg , it is commonly recorded as 120 80
  通常量度压力是以毫米水银柱（ mmhg ）为单位，心脏收缩时的压力叫收缩压，通常是120mmhg左右，心脏舒张时的压力叫舒张压，通常是80mmhg左右，记录如下12080mmhg 。
• Because pressing of arteries and veins increased the impact to blood - vessel greatly , this is , make easy exhaustion mixes the stretch ingredient of tube wall rupture , easy development is aneurism and possible burst , at the same time of hemal wall inside film is injured easily and bring about sclerosis of arterial congee appearance and thrombosis , the hemal sclerosis that and be pressed with wide arteries and veins coexists and diastolic pressure are too low return burden of can aggravating heart and blood of influence coronal arteries and veins to offer
  这是因为脉压大就增加了对血管的冲击，使管壁的弹性成分轻易疲惫和断裂，易发展为动脉瘤并有可能破裂，同时血管壁的内膜轻易损伤而导致动脉粥样硬化及血栓形成，并且与宽脉压并存的血管硬化及舒张压过低还会加重心脏负担和影响冠脉血供。
• We have successfully designed an experiment system for the no invasion blood pressure measurement with our own ip . in our research and develop task we have done a lot work to study foreign instrumen and design ideas . this experiment system is based on msp430 series mpu with excellent erformance and applies advanced digital signal process and intelligent technology . in hardware design , the following means were applied : after a lot of experment and fully knowing about the characteristic of the pulse wave signal , we have designed the accurate and credible circuit to collect the pulse wave signal ; power circuit , communicaion circuit , power drivers circuit have been disigned for the instrument . in software design , the following arithmetic were applied : 1
  软件方面进行了以下算法研究: 1 .综合试验各种数字信号处理方法对波形进行平滑处理: 2 .采用lms自适应方法对脉搏波信号进行了降噪处理; 3 .应用微分闭值法提高了脉搏波信号的检出率，有效识别了运动干扰引起的伪波信号; 4 .利用测振法基本原理并进行大量实验的基础上，提出了比较准确可行的收缩压和舒张压的识别算法，使测振法在本无创血压仪中得到了完整而充分的应用。
• Tall wrestle blood , it is to show difference of pressing of arteries and veins is bigger , you did not inform blood pressure numerical value , if arteries and veins approachs infinity , diastolic pressure is too low , it is even 0 , systole pressing is tall , give priority to arterial valve closedown likely not complete , heart colour exceeds the likelihood to be made clear further
  高搏血，是指脉压差比较大，你未告知血压数值，假如脉压无穷大，舒张压过低，甚至为0 ，收缩压高，有可能为主动脉瓣闭锁不全，可能心脏彩超进一步明确。
• Results after intervention , blood pressure of the whole subjects were under control and kept the level of baseline data ; the rate of increase of prevalence in the intervention areas was below the rate of that from 1979 to 1991 in china ( the former was 14 . 7 % , while the latter was 53 . 7 % ) ; the incidence rate of the subjects was 1 . 4 % , close to the average rate of age 15 and above in china ; the rates of awareness , treatment and control were above the levels of baseline data ; sbp and dbp of the patients decreased by 2 . 9 % and 5 . 6 % , respectively ; while the rate of having high risk factors reduced by 13 . 4 % on average
  结果通过干预，全部调查对象的收缩压和舒张压基本控制在基线时的水平；干预社区患病率的上升速度低于我国从1979年到1991年高血压患病率的上升速度(前者为14 . 7 ，后者为53 . 7 ) ；调查人群的年发病率估计值为1 . 4 ，接近全国15岁及以上人群1 . 0的发病率；高血压患者的知晓率、治疗率和控制率明显高于基线时的水平；高血压患者收缩压和舒张压均值较基线分别下降了2 . 9和5 . 6 ；高危人群各类高危因素的比例平均下降了13 . 4 。
