PEDIATRIC INTRA-AORTIC BALLOON PUMP

静脉空气栓塞症，可发生在多种临床 情况，特别是坐着的神经外科病例，可能是 如果空气到达全身的话会致命或导致严重的疾病 循环(心脏和大脑)。第一阶段的研究表明 即：1)早期空气检测和排出(&lt；45秒)；2)导管 构型(阻力、长度和位置)；3)吸气 流速(最小250毫升/分钟)都是至关重要的 气栓成功取出术。 在第二阶段，我们将制造和测试一个完整的临床 包括遥控真空的静脉空气回收系统 储液器和泵、压力监测器、导管(用于回收 心脏上方和下方的进气口)、管件和空气检测 方法：研究方法。一种安全可靠的静脉空气自动回收系统 早期、有效的血管空气检测可以标准化 护理空气栓塞症高危患者，减少 发病率和死亡率。

Venous air embolism, which may occur in a variety of clinical circumstances, particularly sitting neurosurgical cases, can be lethal or cause severe morbidity if the air reaches the systemic circulation (heart and brain). Phase I studies have demonstrated that: 1) early air detection and removal (<45 sec.); 2) catheter configuration (resistance, length, and position); and 3) aspiration flow rate (minimum of 250 cc/min.) are all critical to the successful removal of bolus air emboli. During Phase II we will fabricate and test a complete clinical venous air retrieval system including a remotely actuated vacuum reservoir and pump, pressure monitors, catheters (for retrieval of air entry above and below the heart), tubing set, and air detection methods. A safe, reliable automated venous air retrieval system with early, effective vascular air detection could standardize the care of patients at risk for air embolism and decrease the morbidity and mortality.
