This application proposes to finish development of a method of monitoring and recording the pulmonary function of asthmatic and other pulmonary patients. Prototypes in Phase I successfully demonstrated the feasibility of such devices. The device measures the pulmonary peak flow. It displays the results instantaneously on an LCD screen. The unique capacity of this device is its ability to record the actual measured peak flow together with the date and time of each measurement over a four month period. This complete record of pulmonary status across time can then by retrieved by the patient's physician to aid in clinical decision-making. Phase I of this proposal was a feasibility study. In Phase II Forefront's specific aims to: 1. Complete the design of the Peak Flow device, 2. Complete the design and implentation of the interpreter software which retrieves data from the Peak Flow device and presents data analysis, 3. Design and build 200 units for study, 4. Validate the performance of these units with internal testing, and most importantly, 5. Validate the clinical significance with a two center study using the 200 units. This device will have significant applications for physicians interested in tracking patients' peak flow measurements across time without requiring daily record keeping by patients. In addition, this device could be used as both a clinical and a research tool in the study of bronchodilator efficacy in home settings. The hope is that it may be utilized to improve the treatment of asthma.

本申请建议完成监测方法的开发 并记录哮喘及其他肺功能 患者 第一阶段的原型成功地展示了 这些设备的可行性。 该设备测量肺部峰值 流 它将结果即时显示在LCD屏幕上。 的 该设备的独特能力是它能够记录实际的 测得的峰值流量以及每次测量的日期和时间 在四个月内。 肺功能的完整记录 然后可以由患者的医生检索以帮助 临床决策。 该提案的第一阶段是可行性研究。 在第二阶段 Forefront的具体目标是：1.完成高峰流量的设计 设备，2.完成解释器的设计与实现 从峰值流量装置检索数据并显示数据的软件 分析，3。设计和建造200个单元用于研究，4。验证 这些单位的性能与内部测试，最重要的是， 5.通过一项双中心研究证实了其临床意义， 200单位。 该设备将有重要的应用感兴趣的医生 在跟踪患者的峰值流量测量时， 需要患者每天记录。 此外，该设备 可用作临床和研究工具， 支气管扩张剂在家庭环境中的疗效。 希望是， 用于改善哮喘的治疗。
