Abstract

Software is described which collects and analyzes pulsatile analog signals using an APPLE PC and a modestly priced analog-digital interface. The program will input and output data, store and retrieve data to disk and display data on the monitor. Four types of data analysis determine mean, maximum and minimum values and frequency in various combinations. For example, the present program analyzes cardiovascular signals for heart rate, stroke volume, cardiac output, systolic, diastolic and mean pressures over a representative 10 s period. Simple modifications to the program are described which extend its range of application.

摘要

本文描述了一种软件，它使用苹果电脑和价格适中的模数接口来收集和分析脉动模拟信号。该程序将输入和输出数据、将数据存储到磁盘并从磁盘检索数据，以及在监视器上显示数据。四种类型的数据分析可以确定各种组合下的平均值、最大值、最小值和频率。例如，当前程序在一个具有代表性的10秒时间段内分析心血管信号的心率、每搏输出量、心输出量、收缩压、舒张压和平均压。文中还描述了对该程序的简单修改，这些修改扩展了其应用范围。
