Pressure and Flow in Arteries and Veins

Question 1

How is arterial pressure measured?

Answer 1

Auscultation of Korotkoff sounds using sphygmomanometer and stethoscope

Question 2

Define systolic blood pressure

Answer 2

The maximum arterial pressure during contraction of the left ventricle

Question 3

Define diastolic blood pressure

Answer 3

The minimum arterial pressure during relaxation and dilation of the ventricles of the heart when the ventricles fill with blood

Question 4

Define pulse pressure

Answer 4

Systolic pressure - Diastolic pressure

The force the heart generates each time it contracts

Question 5

Relate systolic pressure to Korotkoff sounds

Answer 5

Systolic pressure is taken to be the pressure at which the first korotkoff pressure is first heard

Question 6

Relate diastolic pressure to Korotkoff sounds

Answer 6

Diastole pressure is taken to be the pressure at which the fourth korotkoff pressure is just heard
