您要查找的是不是:
- The peak-systolic/diastolic ratio(S/D), pulse index (PI) and resistance index(RI) values of UA were calculated. 结果:正常妊娠时上述各指标随孕周的增加逐渐下降,表明胎盘为低循环阻力器官,其阻力随孕龄增加而下降。
- The difference of pulse pressure(PP),pulse index(PI)and CWS reflecting arterial flexibility was different between the two groups(P<0.01). 颈动脉斑块组与正常对照组比较;反映动脉弹性的脉压(PP)、脉压指数(PI)、平均管壁张力(CWS)差异有显著性(P<0.;01);
- Methods:The blood flow impedance of fetal UA,MCA such as the peak-systolic/diastolic ratio(S/D),pulse index(PI) and resistance index(RI) were measured by color Doppler ultrasound. 方法:应用彩色多普勒超声胎儿监测脐动脉、大脑中动脉S/D、PI、RI等血流指标。
- The pulse index(PI) in the three groups of LA were significantly higher than those of the controls( P<0.01), and the PI in moderate and severe LA groups were significantly higher than those of the control and the mild groups ( P<0.01). 轻、中、重 3组LA患者脉动指数 (PI)显著高于正常对照组 (P <0 0 1;P <0 0 0 1) ;中、重度组LA患者PI显著高于正常对照组及轻度组 (P <0 0 1;P <0 0 0 1)。
- Respiration is difficult at great heights. 在很高的高原上呼吸很困难。
- An unwanted false electronic pulse. 一种不希望有的假电子脉冲。
- Respiration becomes difficult at great heights. 在很高的地方呼吸就变得困难了。
- Objective To observe pulsative index (PI), resistant index (RI) of placental helicine arteries by colour Doppler, analyses relation between PI, RI and developing of pregnant hypertension. 目的本研究采用彩色多普勒检测孕妇子宫胎盘床螺旋动脉搏动指数(PI),阻力指数(RI),预测妊高征的发生、发展及预后。方法选择无慢性高血压,心、肝、肾合并症正常孕妇184例。
- The measurements included the internal diameter(D),the maximal velocity in systole(V max ),the minimal velocity in late diastole (Vmin),the mean velocity(),the blood flow volume per minute(Q),the resistance index(RI), the pulsative index(PI) of LRA. 测量内容包括LRA的内径(D),收缩期最大血流速度(Vmax)、舒张末期最低血流速度(Vmin)、平均血流速度(V)、每分钟血流量(Q)、阻力指数(RI)和搏动指数(PI)。
- Abstract: Objective To observe pulsative index (PI), resistant index (RI) of placental helicine arteries by colour Doppler, analyses relation between PI, RI and developing of pregnant hypertension. 摘 要: 目的本研究采用彩色多普勒检测孕妇子宫胎盘床螺旋动脉搏动指数(PI),阻力指数(RI),预测妊高征的发生、发展及预后。
