Our long-term objective is the development of expert systems using fuzzy logic for sophisticated, rapid analysis of physiologic data in intensive care units. Our immediate objectives are to tune and extend our Phase I pulmonary artery catheter data system to alarm nursing staff on invalid data, and to conduct clinical trials to test whether the system will improve patient care. The existing single-bed system will be adapted to multi-bed and Hewlett-Packard, Marquette and Space Labs physiolgoic monitors. Eighty patients at ICUs in two hospitals will participate in final system development, and an additional 200 patients will participate in a clinical trial of system effectiveness in reducing the number and duration of pulmonary artery catheter abnormalities. (Our tests indicate that the incidence of catheter malfunction may be badly underestimated.) We will also study the expansion of the expert system to include additional information including SvO2 and cardiac output, and to deliver more informative messages to nurses and physicians. Finally, the system will be made suitable for commercial use.

我们的长期目标是使用以下方法开发专家系统 模糊逻辑用于对生理数据进行复杂、快速的分析 重症监护病房。 我们的近期目标是调整和扩展 我们的一期肺动脉导管数据系统用于警报护理 工作人员对无效数据进行临床试验以测试是否 该系统将改善患者护理。 现有单床系统 将适应多床和惠普、马凯特和太空 实验室生理监测仪。 两家医院 ICU 的 80 名患者 将参与最终的系统开发，另外200 患者将参加系统有效性的临床试验 减少肺动脉导管的数量和持续时间 异常。 （我们的测试表明导管的发生率 故障可能被严重低估。）我们还将研究 扩展专家系统以包含更多信息 包括 SvO2 和心输出量，并提供更多信息 给护士和医生的信息。 最后将把系统做成 适合商业用途。
