AUTO BP Quiz

blood pressure

pressure of circulating blood against the arteries

systolic bp

top number where korotkoff sounds become audible due to stroke volume and arterial wall stiffness

diastolic bp

bottom number, korotkoff sounds are muffled. arterial tone (TPR) and blood volume are main influences

stroke volume

amount of blood pumped out of the left ventricle during systolic. 1/3 of blood is left in heart. determines output of blood by the heart per minute

korotkoff sounds

1. sharp thud- systolic

2. soft swishing

3. thud

4. softer blowing muffled

5. silence

blood pressure equation

blood pressure= cardiac output x total peripheral resistance

cardiac output equation

cardiac output= stroke volume x heart rate

mean blood pressure equation

mean blood pressure= diastolic + 1/3 pulse pressure

pulse pressure equation

pulse pressure = systolic - diastolic

what does FMS nanocore measure?

volume

cardiac output equation

cardiac output = stroke volume x heart rate
