Card Set Information
CVR intro blood pressure
Introduction to EDV, ESV, blood pressure, compliance,
What are the parts of the CV system?
These arteries have a lot of connective tissue
Those closest to the heart
Exchange of nutrients, wastes and gases happens here
These join to make veins
What is normal resting heart rate?
What is the effect of age on heart rate?
What is End Diastolic Volume?
What is End Systolic Volume?
How do you calculate stroke volume?
EDV - ESV
What is Diastolic Filling Volume?
Blood which goes from atria to ventricle during
How do you calculate cardiac output?
SV x HR
5L / min
What factors affect stroke volume?
amount of blood in ventricle
force of contraction
How do you calculate venous return?
DFV x HR
What is the function of the heart?
generate pressure to maintain circulation
Why is the right ventricle weaker?
It has to overcome less resistance
Where does the lesser circulation go?
right ventrical to lungs to left atrium
The pulmonary and systemic circulations are arranged in this
Within the greater circulation, capillary beds are arranged in this
This is where blood meets most resistance
What does systolic pressure mean?
Pressure of blood exerted on arteries while heart is in systole
What is blood pressure in lesser circulation?
25 / 10
What is the pressure gradient in systemic circulation?
93 mm Hg
MAP - pressure in right atrium
How does old age affect blood pressure?
blood pressure increases
cuz kidneys change
and arteries harden
How do you calculate Vascular Distensibility?
/ (increase in
These vessels have high compliance
These vessels have low compliance
What is the formula for
distensibility x volume
"It is the total quantity of blood that can be stored in a given portion of vasculature for each mmHg rise in pressure"
