hemodynamic monitoring

Question 1

stroke volume

Answer 1

amount of blood pumped out of the heart (left ventricle - to the body) during each contraction measured in mL/beat

Question 2

preload

Answer 2

preload is stretch. the amount of volume being returned to the right side of the heart from systemic circulation.

Question 3

afterload

Answer 3

afterload is squeeze. the amount of resistance the left side of the heart has to overcome in order to eject blood.

Question 4

contractility

Answer 4

ability to contract

Question 5

cardiac output

Answer 5

blood volume pumped by heart in one minute

Question 6

cardiac index

Answer 6

haemodynamic parameter that relates the cardiac output (CO) from left ventricle in one minute to body surface area (BSA), thus relating heart performance to the size of the individual. unit of measurement is litres per minute per square metre (L/min/m2).
