Abstract
The task of the instrumentation system is to measure cardiac output in animals like rats, dogs, etc. A thermal-dilution method is used for this purpose. The temperature change due to injection of saline is picked up by thermo-couple microprobes implanted in the blood-vessel. The signal after conditioning is fed to a data acquisition system controlled by a computer.
With the help of a computer it is thus possible to monitor and control an experiment on several animals. The computer can sample the chambers sequentially. The sampling cycle duration and frequency are programmable. The data is collected and processed to determine the absolute value of cardiac output.
Presently the system is built to accomodate one animal but it can be expanded to sixteen. Programming in a high level language (FORTRAN) makes it easy to use. Future scope for expansion and advanced processing is explored.
