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.

静脉空气栓塞，这可能发生在各种临床 在某些情况下，特别是坐着的神经外科病例， 如果空气到达全身， 循环（心脏和大脑）。 第一阶段的研究已经证明 （1）早期发现和排除空气（<45秒）; 2)导管 配置（阻力、长度和位置）;以及3）抽吸 流速（最小250 cc/min）都是至关重要的 成功清除了空气栓塞。 在第二阶段，我们将制造和测试一个完整的临床 包括远程致动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 心脏上方和下方的空气入口）、管路套件和空气检测 方法. 安全可靠的自动静脉空气回收系统 通过早期有效的血管空气检测， 护理有空气栓塞风险的患者， 发病率和死亡率。
