Terms in this set (40)
Perfusion Refers to the flow of blood through
arteries and capillaries, delivering
nutrients and oxygen to cells and
removing cellular waste products
Ischemia Lack of blood supply results in cellular injury,
reversible
Systole Contraction phase of the heartbeat; ventricles
contract
Diastole Relaxation phase of the heartbeat; ventricles
relax & fill with blood
Cardiac Output The volume of blood pumped out by the heart
over 1 minute.
Stroke Volume The volume of blood pushed out of the left
ventricle per beat
Cardiac Output Cardiac output= Stroke volume x Heart rate
Equation
Contractility Force required to eject blood from the left

ventricle
Preload Degree of stretching of the ventricle at end of
diastole
Afterload Amount of resistance of force that
occurs when the heart ejects blood from
the left ventricle
Systemic Vascular The pressure that the ventricles work
Resistance (SVR) against to get the valves of the heart
open to get blood through. Impacted by
diameter of vessel
Vasoconstriction When blood vessels become narrow, blood
pressure increases. Increased SVR.
Vasodilation Widening of the blood vessels that allows
for increased blood flow, blood pressure
decrease. Decreased SVR.
Begins with the electrical signal.
Central perfusion Generated by heart muscle contraction.
Ventricles relax to fill with blood and
contract to eject blood to lungs and
throughout the body. Requires adequate
function of heart and blood volume
Blood flow through arteries and
Tissues perfusion capillaries to target tissues. Pressure
pushes blood through capillaries. Blood
pressure is maintained as arteries
constrict and dilate.
Requires patent vessels, adequate pressure, and
permeability.
Norepinephrine A neurotransmitter involved in arousal,
