Hemodynamics Cheat Sheet: Cardiac Output/Index, Mean Arterial Pressure Pulmonary Artery Wedge Pressure (PAWP), Pulmonary Vascular Resistance 

Vascular resistance is the resistance that must be overcome to push blood through the circulatory system and create flow.The resistance offered by the systemic circulation is known as the systemic vascular resistance (SVR) or may sometimes be called by the older term total peripheral resistance (TPR), while the resistance offered by the pulmonary circulation is known as the pulmonary vascular resistance (PVR).

Specific variables include blood volume and viscosity, venous  Vascular Resistance. Kärlmotstånd It is equal to the difference in BLOOD PRESSURE across the vascular bed divided by the CARDIAC OUTPUT. These sex and age differences in vascular resistance are largely a result of cardiac output and total peripheral resistance (TPR) in normotensive humans. av SJ Järhult · 2010 · Citerat av 3 — sphincters, form a widespread network governing peripheral resistance by local stimuli and increases to enhance cardiac output (CO) [72]. When this cardiac  In most people with established essential hypertension, increased resistance to blood flow (total peripheral resistance) accounts for the high pressure while  A=peripheral resistance ×cardiac output. B=blood volume×peripheral resistance.

Ray 2000; Since HR and peripheral resistance controls are characterized by  One potential detrimental effect is a decrease in cardiac output due to coronary of CI, stroke volume and total peripheral resistance are performed using the  “Blood pressure is dependent on cardiac output and peripheral vascular resistance. Systolic blood pressure rises with increasing dynamic work as a result of  The Frank-Starling mechanism allows the cardiac output to be synchronized with AVP constricts arterioles, which increases peripheral vascular resistance and  P: pressure, R: total peripheral resistance (TPR), Q: mean arterial pressure (MAP). P0=MAP Q=cardiac output= Pa-Pv/TPR = MAP/TPR. MAP = c.o. x TPR ! The drug had beneficial effects on cardiac haemodynamics (decreased left and right ventricular filling pressures, reduced total peripheral vascular resistance,  Patterson, R.P. and J. Zhang, Impedance cardiographic measurement of the plethysmography, is an independent predictor of adverse outcome in heart failure.

Increases in peripheral resistance, blood volume, and cardiac output result in higher blood pressure. Conversely decreases in any of these factors lead to lower blood pressure. Three main sources of peripheral resistance: Blood vessel diameter, blood viscosity, and total vessel length.

Following are some of the conditions that can decrease the Peripheral Resistance and at the same time increase the Cardiac Output to above the normal. 1.

PhysioZ. 38): Rl126- R1132, 1995.-Stroke volume (SV) and cardiac output (CO) were measured in anesthetized larvae of Xenopus Zaevis from 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 Prevalence of elevated cardiac output indexed for height(1.83) increased and for elevated total peripheral resistance-height(1.83) index decreased with greater overweight, whereas opposite trends were seen when cardiac output and total peripheral resistance were indexed for BSA or FFM. AIM: This study examined the total peripheral vascular resistance (TPVR) and cardiac output changes due to the head-up tilt test (HUTT) in children with vasovagal syncope (VVS).

mean arterial pressure = total peripheral resistance ꞏ cardiac output. MAP = TPR ꞏ CO. Blood Pressure = Cardiac Output X Peripheral Resistance. Preload 

In the recumbent position, patients with borderline hypertension have increased cardiac output and "normal" peripheral resistance. Under all other experimental conditions, the peripheral resistance in patients with borderline hypertension was elevated. Increased resistance was accompanied by a decrease of the cardiac output. In young adulthood, this condition was mediated by heightened adrenergic activity.
