What % of the cardiac 20%
cycle is provided by the
atrial kick? Atrial kick is a term that represents the amount of
• 15% the total CO that is supplied via atrial contraction.
• 20% If the pt has a condition or dysrhythmia that impairs
• 30% or eliminates the atrial contraction, the pt may be
• 35% compromised.

The EF should be more than 50%. It represents the
A normal value for an EF
amount of blood ejected from the left ventricle
would be?
compared to the total amount available, expressed
• 65%
as a %. An EF of 35% or less indicates a problem with
• 40%
contractility, outflow or filling.
• 30%
• 25%
EXA: If the ventricle contains 90ml of blood and
50mls are ejected, the amount would be expressed
as a %, in this case 55%.

The resistance against Pulmonary Vascular Resistance
which the right ventricle
must work to eject its This pressure represents a mean pressure in the
volume is known as systemic vasculature. The higher the resistance, the
• Resting heart pressure harder the heart has to work against it.
• Systemic vascular
pressure EXA: Colder temperatures will cause
• Central venous pressure vasoconstriction; the heart then has to pump harder
• Pulmonary vascular to deliver blood through the narrowed vasculature.
