Definitions
The force that the blood places on the walls of our vessels.
Blood Pressure
What is the "normal" range for Strove Volume?
60 - 100 mL/beat
The stretch placed on the walls of the ventricle caused by the filling of blood just before contraction.
Preload
The resistance placed on the blood when moving through the vessels. Also referring to how constricted or dilated vessels are.
Systemic Vascular Resistance
Can indicate that a patient will be fluid responsive, as well as if the patient might tolerate weaning off pressors.
Eadyn
When the heart is at rest, it is in __________.
Diastole
What is the "normal" range for Cardiac Output?
4 - 8 L/Min
The squeeze of the heart.
Contractility
Vasodilation causes SVR to ________.
Decrease
Relative measurement of LV contractility and function.
dP/dt
The volume ejected from the heart each beat.
Strove Volume
What is the "normal" range for Pulmonary Artery Pressure?
20s / 10s (Quarters over Dimes)
The resistance the heart has to overcome to eject blood from the ventricle.
Afterload
Vasoconstriction causes SVR to ________.
Increase
Norepinephrine activates what receptors?
Mostly Alpha; Some Beta
The total volume ejected from the heart per minute.
Cardiac Output
What is the "normal" range for SVRI?
1970 - 2390
Increasing preload will _______ stroke volume.
Increase
My patient's SVR is 1600. What does this measurement indicate?
Patient's vessels are constricted.
Ensure the tank is FULL.
Stroke volume is dependent on what 3 factors?
Preload, afterload, contractility
What is a "normal" range for Cardiac Index?
2.5 - 4 L/min/m2
Increasing afterload will ________ stroke volume.
decrease
Add a pressor/increase pressor if already on one.
Principle that states the more the heart muscle is stretched before contraction (preload), the stronger the contraction and the greater the volume of blood ejected.
