Wireless technology is a growing presence in medical applications. A recent entry in the field is the LifeSync Wireless ECG System manufactured by GMP Wireless Medicine. The LifeSync transmits electrocardiogram (ECG) and respiration waveforms wirelessly from the patient to a physiologic monitoring device (bedside monitor, transport monitor, or 12-lead ECG cart), allowing the elimination of traditional ECG leadwires connecting the patient to the monitoring device. This wireless ECG monitoring is designed to reduce restrictions on patient movement, ease transport, and simplify clinicians' lives compared to the use of traditional hardwired ECG systems. Our Evaluation examines whether, in fact, the LifeSync accomplishes these goals. Most of our findings focus on ease-of-use issues, although cost also carries significant weight in our judgments. The LifeSync's lead set, the LeadWear Disposable Cable Replacement System, is disposable and radiolucent, and its electrodes are all connected along a single cable rather than being separate strands. In addition to its use with the full LifeSync system, the LeadWear can also be used by itself--without the wireless component-in place of standard ECG leadwires. Our Evaluation includes a separate rating for using the LeadWear in this way, in what we call the LeadWear-only approach.
无线技术在医疗应用中的应用日益广泛。该领域最近出现的一款产品是由GMP无线医疗公司生产的LifeSync无线心电图系统。LifeSync可将心电图(ECG)和呼吸波形从患者身上无线传输到生理监测设备(床边监护仪、转运监护仪或12导联心电图推车),从而无需使用将患者与监测设备相连的传统心电图导联线。与使用传统有线心电图系统相比,这种无线心电图监测旨在减少对患者活动的限制,便于转运,并简化临床医生的工作。我们的评估将考察LifeSync是否真的实现了这些目标。我们的大部分调查结果都集中在易用性问题上,不过成本在我们的评判中也占有重要比重。LifeSync的导联套装,即一次性可透射线的LeadWear电缆替换系统,其电极都沿着一根电缆连接,而非单独的导线。除了与完整的LifeSync系统配合使用外,LeadWear也可单独使用——不使用无线组件——来替代标准心电图导联线。我们的评估对以这种方式使用LeadWear给出了单独评分,即我们所说的仅使用LeadWear的方法。
