COMPUTER—BASED DYSTEM FOR REAL TIME ANALYSIS OF HEMODYNAMIC SIGNALS IN EXPERIMENTAL ANIMALS / 医疗卫生装备

ABSTRACT

A computer-based system for real time analysis of hemodynamic signals in experimen- tal animals was developed by using an IBM-PC/XT microcomputer and a polygraph.The sys- tem software was written in compiler with BASIC and 8088 assembly language.The system per- forms six functions(1)Acquisition of hemodynamic signals;(2)Extraction of signal feature point;(3)Storage of experimental data on the floppy disk;(4)Calculation of 10 hemodynamic parameters;(5)Printout of the data both in tables and in figures;(6)Statistical analysis of exper- imental data. Pharmacological studies have been carriedout by using the system to evaluate the activities of well-know drug as well as some Chinese medicines on cardie-vascular system.The reliability and practicability of the system were confirmed by the experimental data.
