Cardiovascular/CAD/PAD/Pulmonnary Flashcards
Flash cards for exam 3
Blood flows from the RA thru the __ valve
Tricuspid
Blood flows from the LA thru the __ valve
Mitral
Blood flows from the RV thru the __ valve
Pulmonary
Blood flows from the LV thru the __ valve
Aortic
Heart valves in order of flow:
Tricuspid
Pulmonary
Mitral
Aortic
Average stroke volume:
70mL/Beat
Cardiac output is determined by:
SV X BPM
Ability of the heart muscle to pump effectively!
Cantractility
Volume of blood in ventricles before contraction
Preload
Pulmonary vascular Resistance
RV afterload
Systemic vascular resistance
LV afterload
RV afterload can cause
right sided heart failure
LV after load can be too high due to:
HTN or atherosclerosis/arteriosclerosis
RV afterload can be caused by
atherosclerosis/arteriosclerosis of pulmonary vessels; stiff, noncompliant lung tissue
Normal preload value:
~4-6 L/min
Blood flow back to the heart
venous return
Most venous disorders occur in:
the legs
CVI
chronic venous insufficiency
DVT
deep vein thrombosis
CVI & DVT are usually related to problems pertaining to:
maintaining forward flow
AKA “valve incompetence”
Venous insufficiency
Pooling of blood due to venous insufficiency
venous congestion
Factors contributing to venous congestion
Gravity (standing for long periods)
Valve incompetence
Worn out, “floppy” valves in leg veins
Venous insufficiency
