Identify the 3 main factors that affect stroke volume.
contractility
preload
heart rate
afterload
(a) is described as the backpressure by arterial blood.
If a patient is taking calcium channel blockers, what does that do to their stroke volume?
increases stroke volume
decreases stroke volume
nothing, it will stay the same
If preload increases, what does that do to the cardiac output (if the heart rates stays the same)?
increases cardiac output
decreases cardiac output
nothing
stays the same
Stroke volume represents.....
How much blood the ventricles pump out.
How fast the ventricles pump blood out.
Cardiac output.
Heart rate
What will increase afterload?
Calcium ions
exercise
blood loss
vascular resistance
If afterload increases, what does it do to the cardiac output (if heart rate stays the same)?
Increases cardiac output
Decreases cardiac output
Nothing
stays the same
______ is the resistance to flow that must be overcome for the blood to flow through the circulatory system.
Vascular resistance
Afterload
Preload
Venous pressure
