Chapter 16- Blood Pressure

Question 1

blood pressure measurement

Answer 1

Done by applying air to a pressure of about 170 to 180 mmHg, to the artery, which stops the flow of blood through the artery. Air is then released from the cuff. The larger or top number in the blood pressure matches the pressure at which the heart can force blood through the brachial artery past the cuff during ventricle contraction. The smaller or bottom number in the blood pressure matches the pressure at which blood begins to flow freely through the brachial artery and past the cuff in between ventricular contractions.

Question 2

diastole

Answer 2

The part of the heart beat that occurs as the ventricles relax; ventricular relaxation in low diastolic blood pressure

Question 3

hypertension

Answer 3

A condition characterized by above normal blood pressure

Question 4

hypotension

Answer 4

A condition characterized by below normal blood pressure

Question 5

sphygmomanometer

Answer 5

The instrument used to measure blood pressure

Question 6

systole

Answer 6

The part of the heartbeat that occurs as the ventricles contract; ventricular contraction is powerful and generates high systolic blood pressure
