体外反搏是一种无创伤治疗多种缺血性疾病的有效新技术,在医学临床应用已有十六个年头。国内现有体外反搏机品种近十多种,各有所长,都采用耳垂脉搏波作为反搏定时的效应指标。这种方法的明显不足之处是不能正确反映心脏收缩期和舒张期的界限,无明显的切迹点存在,所以其充排气时间依赖临床经验,靠手动控制进行调整。这 Extracorporeal counterpulsation is a non-invasive treatment of a variety of ischemic diseases effective new technology, clinical applications in medicine for sixteen years. Nearly a dozen of the existing types of external pacing machines in the country have their own advantages and disadvantages. All of them use the lobes of ear lobes as the countermeasures of the counterpulsation timing. The obvious disadvantage of this method is not able to correctly reflect the systolic and diastolic boundaries, there is no obvious cut-point exists, so the time of its exhaust depends on clinical experience, by manual control to adjust.
