Establishment of computer-aided acquisition system of complete blood pressure wave parameters in rats.
OBJECTIVE
To establish an accurate and efficient system for acquiring the complete blood pressure wave parameters in rats.


METHODS
With the help of Powlab, the equipment for physiological data recording, and Chart (soft ware), the basal parameters of the the blood pressure waves were acquired in rats, including the parameters of a single wave and the average parameters recorded in 1 min, which were then processed according to mathematical formulas or calculated approximately to acquire other parameters.


RESULTS
Through the system the complete parameters of the blood pressure waves were acquired accurately in rats. Compared with the actual values, the results from some approximate calculation showed little difference.


CONCLUSIONS
A precise and automated system for acquiring complete parameters of the blood pressure waves is successfully established in rats, which makes possible more comprehensive and convincing analysis of the blood pressure waves in rats.
