In today's intensive care and surgery, a great number of cables are attached to patients. These cables can make the care and nursing of the patient difficult. Replacing them with wireless communications technology would facilitate patient care. Bluetooth is a modern radio technology developed specifically to replace cables between different pieces of communications equipment. In this study we sought to determine whether Bluetooth is a suitable replacement for cables in intensive care and during surgery with respect to electromagnetic compatibility. The following questions were addressed: Does Bluetooth interfere with medical equipment? And does the medical equipment decrease the quality of the Bluetooth communication? A Bluetooth link, simulating a patient monitoring system, was constructed with two laptops. The prototype was then used in laboratory and clinical tests according to American standards at the Karolinska Hospital in Stockholm. The tests, which included 44 different pieces of medical equipment, indicated that Bluetooth does not cause any interference. The tests also showed that the hospital environment does not affect the Bluetooth communication negatively.
Bluetooth, a new radio technology transmitting at 2.4 GHz, was tested in a clinical setting. The study showed that a single Bluetooth link was robust and electromagnetically compatible with the tested electronic medical devices.
在当今的重症监护和外科手术中，大量电缆连接在患者身上。这些电缆会给患者的护理带来困难。用无线通信技术取代它们将便于患者护理。蓝牙是一种专门为取代不同通信设备之间的电缆而开发的现代无线电技术。在本研究中，我们试图确定在电磁兼容性方面，蓝牙是否适合在重症监护和手术中取代电缆。研究解决了以下问题：蓝牙是否会干扰医疗设备？医疗设备是否会降低蓝牙通信的质量？用两台笔记本电脑构建了一个模拟患者监测系统的蓝牙链路。然后，该原型按照美国标准在斯德哥尔摩的卡罗林斯卡医院进行了实验室和临床测试。包括44种不同医疗设备的测试表明，蓝牙不会造成任何干扰。测试还表明，医院环境不会对蓝牙通信产生负面影响。
蓝牙是一种在2.4吉赫兹频段传输的新型无线电技术，在临床环境中进行了测试。研究表明，单个蓝牙链路性能稳定，与测试的电子医疗设备具有电磁兼容性。
