title: Data acquisition and analysis of pulsatile signals using a personal computer: an application in cardiovascular physiology.
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.
