The article describes a study conducted on general surgical and thoracic surgical floors of a 1000-bed hospital to assess the impact of a new network for portable patient care devices. This network was developed to address the needs of hospital patients who need constant, multi-parameter, vital signs surveillance, but do not require intensive nursing care. Bedside wall jacks were linked to UNIX-based workstations using standard digital network hardware, creating a flexible system (for general care floors of the hospital) that allowed the number of monitored locations to increase and decrease as patient census and acuity levels varied. It also allowed the general care floors to provide immediate, centralized vital signs monitoring for patients who unexpectedly became unstable, and permitted portable monitors to travel with patients as they were transferred between hospital departments. A disk-based log within the workstation automatically collected performance data, including patient demographics, monitor alarms, and network status for analysis. The log has allowed the developers to evaluate the use and performance of the system.
本文描述了在一家拥有1000张床位的医院的普通外科和胸外科楼层进行的一项研究，以评估一种用于便携式患者护理设备的新网络的影响。该网络的开发是为了满足那些需要持续、多参数生命体征监测但不需要重症护理的医院患者的需求。床边壁式插座使用标准数字网络硬件与基于UNIX的工作站相连，创建了一个灵活的系统（用于医院的普通护理楼层），该系统允许随着患者普查和 acuity 水平的变化增加或减少被监测位置的数量。它还允许普通护理楼层为意外变得不稳定的患者提供即时、集中的生命体征监测，并允许便携式监测仪在患者在医院各科室之间转移时随患者移动。工作站内基于磁盘的日志会自动收集性能数据，包括患者人口统计学信息、监测警报和网络状态以供分析。该日志使开发人员能够评估系统的使用情况和性能。
