Hemodynamics CCRN
Tx to decrease preload - -Diuretics

-Dilators (nitrates, nitroprusside, morphine)



Define preload - -Preload is the volume/pressure in the ventricle at the end of DIASTOLE after the
AV valves close, just prior to ejection

-As preload increases, SV and CO will increase up to a point

-Too high of a preload may lead to heart failure

-Preload will seldom be elevate if the heart is without disease and there are no metabolic abnormalities



Cardiac output equation - CO = HR x SV



Components of stroke volume - Preload

Afterload

Contractility



Preload components - CVP (right ventricular) - central venous pressure

PAOP (left ventricular) - pulmonary artery occlusive pressure



Afterload components - PVR (right ventricular) - pulmonary vascular resistance

SVR (left ventricular) - systemic vascular resistance



Normal cardiac output - 4-8L/min



CI - -Cardiac index

-take into account body surface area and is a more meaningful value than CO

, Normal cardiac index (CI) - 2.5-4.0L/min/m2



CO and HR - -As heart rate increases

-Cardiac output increases up to a point

-Extreme bradycardia results in low CO and hypotension

-Increase in HR >> first sign of compensation for a low CO



Definition of stroke volume - -How many mL pr beat the left ventricle ejects



Stroke Volume and CO - -As stroke volume increases, cardiac output increases



Normal SV (stroke volume) - 50-100 mL per beat




What pressures reflect the right ventricle preload? - -Right atrial (RA)

-Central venous pressure (CVP)



What pressure reflects the left ventricle preload? - -Pulmonary artery wedge pressure (PAOP)



Define afterload - -Afterload is the pressure (resistance) against which the ventricle must pump to
open the valve (pulmonic and aortic)



How is afterload measured for the right ventricle? - -Pulmonary Vascular Resistance (PVR)



How is afterload measured for the left ventricle? - -Systemic Vascular Resistance (SVR)



Afterload and CO - -As afterload increases, SV and CO decrease
