This paper introduces a display and analysis software based on LabVIEW which is used for displaying and analyzing the interaction of cardiopulmonary. The software encapsulated the arithmetic in the format of component object model in matlab, and achieved the computing function by means of calling the module in LabVIEW. It can and basically analyze the multi-channel physiological parameters, so it is convenient for the continuously and repeatedly observing all parameters. Therefore, it provides an easy video tool for physiological signal, and presents the idea to construct the similar software system.
