- The peak-systolic/diastolic ratio(S/D), pulse index (PI) and resistance index(RI) values of UA were calculated. 結果：正常妊娠時(shí)上述各指標隨孕周的增加逐漸下降，表明胎盤(pán)為低循環(huán)阻力器官，其阻力隨孕齡增加而下降。
- The difference of pulse pressure(PP),pulse index(PI)and CWS reflecting arterial flexibility was different between the two groups(P<0.01). 頸動(dòng)脈斑塊組與正常對照組比較;反映動(dòng)脈彈性的脈壓(PP)、脈壓指數(PI)、平均管壁張力(CWS)差異有顯著(zhù)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:應用彩色多普勒超聲胎兒監測臍動(dòng)脈、大腦中動(dòng)脈S/D、PI、RI等血流指標。
- 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). 輕、中、重 3組LA患者脈動(dòng)指數 (PI)顯著(zhù)高于正常對照組 (P <0 0 1;P <0 0 0 1) ;中、重度組LA患者PI顯著(zhù)高于正常對照組及輕度組 (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難。
- An unwanted false electronic pulse. 一種不希望有的假電子脈沖。
- Respiration becomes difficult at great heights. 在很高的地方呼吸就變得困難了。
- 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檢測孕婦子宮胎盤(pán)床螺旋動(dòng)脈搏動(dòng)指數(PI),阻力指數(RI),預測妊高征的發(fā)生、發(fā)展及預后。方法選擇無(wú)慢性高血壓,心、肝、腎合并癥正常孕婦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. 測量?jì)热莅↙RA的內徑（D），收縮期最大血流速度（Vmax）、舒張末期最低血流速度（Vmin）、平均血流速度（V）、每分鐘血流量（Q）、阻力指數（RI）和搏動(dòng)指數（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檢測孕婦子宮胎盤(pán)床螺旋動(dòng)脈搏動(dòng)指數（PI），阻力指數（RI），預測妊高征的發(fā)生、發(fā)展及預后。
- n： body temperature is used in conjunction with the other vital signs （ respiration ， pulse and blood pressure ） to assess the patient's present condition. 護士：體溫和其他生命體征（如：呼吸、脈搏和血壓）共風(fēng)吹草動(dòng)反應出病人的情況。
- The air inhaled and exhaled in respiration. 呼吸的空氣在呼吸中吸入和呼出的空氣
- He knew the pulse of the nation. 他了解國民的心態(tài)。
- The doctor took my temperature and my pulse. 醫生量了量我的體溫和脈搏。
