The linear association between two continuous quantities is often assessed in terms of Pearson’s correlation coefficient, r. However, if the data are not homogeneous, i.e., consist of groups, then it is important to decompose r into components that measure the correlation within the groups, and the correlation between the groups. We point out the importance of examining these components, and pr...
It has been speculated that if baroafferent signals are only related to the negative feedback control of arterial pressure (AP), then physical activity would increase the range of AP fluctuation in baroafferent-denervated animals. Mean AP (MAP), heart rate (HR), and cardiac output (CO) were measured for 24 h in free-moving conscious rabbits. On the basis of hydrostatic pressure and electromyogr...
Hemodynamic monitoring is used to identify deviations from hemodynamic goals and to assess responses to therapy. To accomplish these goals one must understand how the circulation is regulated. In this review I begin with an historical review of the work of Arthur Guyton and his conceptual understanding of the circulation and then present an approach by which Guyton's concepts can be applied at ...
In cardiovascular reactivity studies, interpretations of the processes supporting the blood pressure response may become problematic when systolic blood pressure, diastolic blood pressure, and heart rate all increase in response to a behavioral challenge. Therefore, in addition to evaluating these cardiovascular responses, this study examined cardiac output, total peripheral resistance and syst...
