One hundred four patients were placed emergently on the Bard CPS portable femoro-femoral bypass system over a 4 year period. Thirty-two patients (31%) were discharged from the hospital. Seventy-six of these patients (73%) required emergency bypass following cardiac arrest, and twenty-eight patients (26%) were in cardiogenic shock or respiratory failure. In the arrest group, no one survived an unwitnessed arrest and those with cardiopulmonary resuscitation times less than 30 minutes had a better survival rate. The highest survival rate was in those patients who did not arrest prior to bypass. Fifty-two percent of these patients were released. The 74 patients receiving interventional therapy on bypass had a higher survival rate than those unable to be treated. Of the thirty patients receiving no intervention, only three (10%) were eventually discharged. For the 19 patients receiving treatment only in the cardiovascular laboratory, the discharge rate was 26%. Of the 55 patients taken to the operating room for surgical correction, 24 (44%) were discharged from the hospital. No patients placed on bypass at an outlying hospital or treated using CPS within 72 hours of a previous open heart procedure survived.
在4年期间，104例患者紧急使用了巴德CPS便携式股-股旁路系统。32例患者（31%）出院。其中76例患者（73%）在心脏骤停后需要紧急旁路，28例患者（26%）处于心源性休克或呼吸衰竭状态。在心脏骤停组中，无人在未被目击的心脏骤停后存活，而心肺复苏时间少于30分钟的患者生存率更高。生存率最高的是那些在旁路手术前未发生心脏骤停的患者。这些患者中有52%出院。接受旁路介入治疗的74例患者的生存率高于无法接受治疗的患者。在30例未接受干预的患者中，最终只有3例（10%）出院。对于仅在心血管实验室接受治疗的19例患者，出院率为26%。在55例被送往手术室进行手术矫正的患者中，24例（44%）出院。在外院进行旁路手术或在前一次心脏直视手术后72小时内使用CPS进行治疗的患者无一存活。
