Wirele Network Accurately and Inexpensively Monitors
Patients\' Breathing
无线网络事实上是廉价地监控着病人的呼吸状况。
A couple years ago we saw wirele technology that would allow us to see through walls.Now,几年以前我们就可以看到无线网络可以让我们看到“墙外的东西”。现在，来自犹他州州立 thesame team of researchers, from the University of Utah, is putting that motion detection大学的同一个技术团队正在把移动式检测技术
technology to work monitoring breathing patterns.So not only can the network see through your 运用到检测病人的呼吸状况上因此通过网络不仅可以远程观察病人的现状，它甚至可以听到 bedroom wall, it can hear you breathing.Le sinisterly, the system could help doctors keep你的呼吸。这个系统可以帮助医生更好的监控患者睡眠时的呼吸暂停事件，急救病人或婴儿 better track of patients with sleepapnea, surgery patients or babies at risk for sudden infant 的发生突然猝死危险性就变得更低了。
death syndrome.
Team leader Neal Patwari demonstrated the system by lying in a hospital bed surrounded by这个团队的带头人尼尔帕特维尔躺在一家医院的病床上，周围布置了20个工作频率为2.4G 20 wirele transceivers operating at a frequency of 2.4 gigahertz.He timed his breathing to be赫兹的无线电收发器以演示这个监控系统的工作状况。他测量并记录他的呼吸在每分钟15 about 15 breaths per minute, confirming this measurement with a carbon dioxide detector.次，并用一个二氧化碳探测器证明了这次测量。
The algorithm accurately measures respiration within 0.4 to 0.2 breaths per minute based on这个监控器能准确得监控呼吸在每分钟0.2次到0.4次每分钟的误差在以只有30秒的基准上， only 30 seconds of data, much better than most monitors, which round off to the nearest full它的精准度超过了大部分测量仪，它能完整的测量最近的所有呼吸状况。

The system will also be cheaper than existing breath monitors, as it uses off-the-shelf wirele而且这个系统比现存的呼吸监控器都要便宜。因为它使用的现成无线电接受器就和我们 transceivers similar to the ones used for home computer networks.The next step for its
家里电脑用的网络设备是差不多的。对于这个团队系统的下一步发展方向是决定能用一个不 development is for the team to determine if a different radio frequency could detect breathing 同的发射频率以比2.4G赫兹更好地监测呼吸还有就是如果这个系统是否能够同时但并不同 better than 2.4 gigahertz and if the system could detect two people breathing at the same time,步地监测两个人的呼吸。除了将这项技术应用与医院以外，帕特维尔还想将它整合并应用于 but not in unison.In addition to providing technology for use in hospitals, Patwari hopes to5年内的婴儿家庭监控系统当中。
integrate the system into at-home baby monitors in five years or so.
