Abstract :
The aim of this study was to assess the cardiopulmonary baroreflex contribution to the maintenance of arterial pressure stability. Twelve young healthy subjects were examined (mean age -25.7 plusmn 4.9 years). Cardiac rhythm and arterial pressure were continuously recorded with the use of finapress technique at rest and in the course of low pressure area receptors deactivation due to lower body negative pressure (-10 mm Hg). The recorded data were processed by special MATLAB program that calculated heart rate (HR) and blood pressure (BP) spectral parameters and also cross-spectral power density between HR and BP. The obtained results demonstrated that CPBR is involved in the process of vessel tone fine regulation by means of both slow and rapid regulating mechanisms.
