Abstract

A complex statistical study of the cardiovascular system in normal and hypotensive states is presented. Signals derived from ascending aorta, iliac artery, and right atrium were analyzed in anaesthetized dogs during observation periods of 30 min. Circulatory waves decomposed by frequency analysis were statistically reduced by correlation functions, power density spectra, etc. A practical view of obtaining the necessary length of observation period and that of stationary test is given. Pulsatile pressure and flow waves can be regarded as a good approximation as stationary for periods of about 10 min. The pulsatile processes of the CVS are likely not to be invariably stationary, not even in anaesthetized animal under standard circumstances.
