Estimation of cardiac output and peripheral resistance using square-wave-approximated aortic flow signal

Estimation of cardiac output and peripheral resistance using square-wave-approximated aortic flow signal

This paper presents a model-based approach to estimation of cardiac output (CO) and total peripheral resistance (TPR). In the proposed approach, the response of cardiovascular system (CVS), described by the windkessel model, is tuned to the measurements of systolic, diastolic and mean arterial blood pressures (BP) so as to yield optimal individual- and time-specific system time constant that is...

Cardiac output and total peripheral resistance in carotid sinus reflex.

SCHMIDT,ROBERT M., MAMORU KUMADA, AND KIICHI SAGAWA. Cardiac output and total peripheral resistance in carotid sinus reflex. Am. J. Physiol. 221(Z) : 480-487. 197 1 .-The sensitivity of the carotid sinus baroreceptor reflex to step change in sinus pressure was studied in anesthetized dogs, with emphasis on the relative contributions of cardiac output (CO) and total peripheral resistance (TPR) i...

Relationship between cardiac output and peripheral resistance in borderline hypertension.

Cardiac output and total peripheral resistance in spontaneously hypertensive rats.

ESPITE extensive studies on spontaneously hypertensive rats, there have been no studies on the cardiac output except a preliminary work by Albrecht et al,4) which reported a decreasing tendency of cardiac output with age. These authors employed the Stewart-Hamilton principle for the measurement of cardiac output. An attempt was made in this study to measure cardiac output in SHR by applying an ...

Blood Flow Measurement: The Cardiac Output and Vascular Resistance

The maintenance of blood flow commensurate with the metabolic needs of the body is a fundamental requirement of human life. In the absence of major disease of the vascular tree (e.g., arterial obstruction), the maintenance of appropriate blood flow to the body depends largely on the heart's ability to pump blood in the forward direction. The quantity of blood delivered to the systemic circulati...
