- This period of hypotension is usually associated with bradycardia, decreased pulse pressure, and decreased cardiac output. 在血压降低时期一般伴有心率减慢，脉压降低和心输出量减少。
- Thus, most cases of bowel ischemia and infarction result from generalized hypotension and decreased cardiac output. 大多数肠局部缺血和梗死的病例，是由于血压过低和心输出量降低引起的。
- However, the patient may be volume depleted and prone to hypotension and decreased cardiac output from mechanical ventilation and PEEP. 不过，病人可能因机械通气和PEEP导致肺容量衰竭，容易出现血压过低和心排量减少。
- As alveoli collapse and fill with fluid, increased shunting of blood occurs, and alveolar hypoventilation, decreased cardiac output, and decreased tissue perfusion develop. 由于肺泡塌陷和充满液体，血液分路增加，出现肺泡换气不足、心排出量下降、组织灌注减少。
- Mechanisms may involve decreased circulating volume decreased cardiac output and vasodilation sometimes with shunting of blood to bypass capillary exchange beds. 休克生理机制涉及循环容量减少、心排量降低和血管扩张，有时伴血液分流，绕过毛细管交换床。
- Decreased cardiac output 心输出量减少
- Cardiac output was measured by thermo dilution. 用热稀释法测定心输出量。
- Results Systolic blood pressure（SBP） and l DBP were decreased and SaO2 and cardiac output were increased after treatment. 本研究旨在探讨利喜定（国产乌拉地尔）治疗充血性心力衰竭的疗效及安全性。
- Cardiac remodeling and cardiac output changes are consistent with a gradual increase in afterload and compromised arterial compliance in conditions of decreased fetal growth. 在胎儿发育迟缓条件下，心脏重塑和心输出量的变化，与后负荷和损害的动脉顺应性的逐渐增加相一致。
- Results After pneumomediastinum(PM),as compared with the baseline measurements,the venacaval pressure raised and the cardiac output decreased significantly. 观察治疗前后的血流动力学和血气变化。结果纵隔气肿使上、下腔静脉压升高,回心血量减少,心排量下降。
- Cardiac output may be influenced by changes of blood gas tensions. 心输出量可受血气分压改变的影响。
- The causes of death werc low cardiac output and severe hypoxemia. 死亡原因低心排、严重低氧血症。
- Maintenance of cardiac output and hemoglobin concentration. 维持心排量和血红蛋白浓度。
- The cardiac output (CO) and Cst decreased significantly when the PEEP was 20 cm H 2O, at the same time, the pulmonary vascular resistance (PVR) and the systemic vascular resistance (SVR) increased (P<0.05). 在PEEP增加到 2 0cmH2 O时心输出量 (CO)和Cst下降 ;外周循环阻力 (SVR)、肺循环阻力 (PVR)和气道峰值压 (PIP)增加 (P <0 .;0 5 )。
- Decreased contractility of myocardium as manifested by a reduction of EPFV and ETVI, and a significant componsatory increase in APFV ,ATVI and the ratio between APFV and EPFV and between ATVI and TTVI in order to maintain the cardiac output. 心肌收缩力下降则使EPFV减慢，ETVI减小，代偿性APFV加快及ATVI加大，A/E及ATVI/TTVI增加，以维持心输出量。
- A resting adult has a cardiac output of about three quarts a minute. 一个处于睡眠状态的成年人的心输出量大约是每分钟3夸脱。
- Cirrhotic cardiomyopathy is one of the complications of liver cirrhosis which can be characterized by diastolic dysfunction,high cardiac output and decreased systemic vascular resistance. 肝硬化性心肌病是肝硬化的并发症之一,主要表现为心脏舒张功能减低、心排血量增加、全身血管阻力降低。
- The supported Fowler position improves cardiac output and ventilation and facilitates urinary and bowel elimination. 支撑弗洛氏位(半坐卧位)改善心排血量和通气作用，促进大小便排泄。
- Cardiac output is derived from the velocity waveform and the patient's parameters (age, weight and height). 综合参考血流速度波形以及病人基本资料(年龄,体重和身高)而得出心输出量的值。
- The two kidneys with a combined weight of some 300g in man, receive 25% of the cardiac output. 人的两肾重约300克，而血供量却为心输出量的四分之一。
