Cardio phys lab

Question 1

method of listening and studying heart sounds

Answer 1

auscultation

Question 2

medical instrument w ear pieces connected to tubes attached to a small disc shape resonator

Answer 2

stethoscope

Question 3

one the heart valves doesn’t function properly

Answer 3

heart murmurs

Question 4

1st heart sound

Answer 4

lub sound
heard during systole
due to closing of atrioventricular valves
tricuspid - right
mitral - left

Question 5

2nd heart sound

Answer 5

dup sound
heard during systole
due to closing of semilunar valves
aortic semilunar valve
pulmonary semilunar valve

Question 6

period of contraction

Answer 6

systole

Question 7

period of relaxation

Answer 7

diastole

Question 8

3rd heart sound

Answer 8

heard during diastole
produced by vibrations in the ventricle wall

Question 9

4th heart sound

Answer 9

heard during diastole
atria contract to push blood into ventricles

Question 10

where sounds of the heart valves can be heard most clearly

Answer 10

auscultatory areas

Question 11

pressure created by the force of blood pushing against the walls of the arteries and heart pumps blood into vessels

Answer 11

blood pressure

Question 12

pressure in arteries when ventricles are contracting

Answer 12

systolic pressure
90-120 mm Hg
important indicator of the force of contraction of the heart

Question 13

pressure in arteries when ventricles are relaxing

Answer 13

diastolic pressure
60-80 mm Hg
important indicator of the condition of the systemic blood vessels

Question 14

difference between systolic/diastolic pressure indicating the force of blood pushing through the vessels

Answer 14

pulse pressure
40 mm Hg

Question 15

the average blood pressure during a cardiac cycle

Answer 15

mean arterial pressure
70-100 mm Hg

Question 16

when vessel diameter decreases

Answer 16

peripheral resistance increases

Question 17

when blood viscosity increases

Answer 17

peripheral resistance increases

Question 18

an increase in CO, or peripheral resistance

Answer 18

increase in blood pressure

Question 19

calculate MAP

Answer 19

map = cardiac output (ml blood/min) x total peripheral resistance (TPR units)

Question 20

calculate cardiac output

Answer 20

CO= stroke volume (ml blood/beat) x heart rate (beats/min)

Question 21

indirect measure of BP - pressure cuff, pressure applied to artery externally

Answer 21

sphygmomanometer
brachial artery

Question 22

palpating the pulse as pressure is applied to the artery

Answer 22

palpatory method
brachial artery

Question 23

utilizes the sphygmomanometer but also requires the use of a stethoscope to hear changes in the sound of the brachial artery

Answer 23

Auscultatory method

Question 24

sounds produced by turbulence in vessels

Answer 24

Korotkoff sounds

Question 25

A sharp tapping or thudding sound, which may increase in intensity over the next 10 mm Hg drop in pressure. This phase indicates the systolic pressure.

Answer 25

phase 1

Question 26

the distinct abrupt muffling of the sounds. They will become soft and reduced in intensity, first diastolic reading

Answer 26

phase 4

Question 27

All sounds disappear, and the absence of sound is considered to be the second diastolic reading

Answer 27

phase 5

Question 28

blood pressure taken on one arm

Answer 28

pulse rate should be taken on opposite arm

Question 29

amount of force affecting resistance to blood flow through the circulatory system

Answer 29

total peripheral resistance

Question 30

if vasoconstriction increases

Answer 30

TPR increases

Question 31

vasodilation increases

Answer 31

TPR decreases

Question 32

calculate TPR

Answer 32

tpr = mean arterial pressure / cardiac output

Question 33

calculate TPRest

Answer 33

TPRest= (systolic pressure + (2 x diastolic pressure))/ 3 ____________________________ pulse pressure x heart rate

Question 34

decrease in temperature

Answer 34

results in increase of systolic and diastolic pressure

Question 35

blood is not returned to heart at a desirable rate

Answer 35

venous insufficiency due to low pressure in veins

Question 36

slowing of heart while underwater and decrease in blood vessel diamater

Answer 36

diving bradycardia/ peripheral vasoconstriction

Question 37

measure of cardiovascular health and endurance, tests capacity of body to cope w increase in physical activity and ability to recover from it

Answer 37

Harvard step test

Question 38

Calculate index of physical fitness

Answer 38

index = duration of exercise (seconds) x 100 ________________________________ 2 x (sum of 3 pulse counts in recovery)

Question 39

the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue

Answer 39

Perfusion

Question 40

test used to measure the ratio of a persons resting pulse to their pulse after exercise

Answer 40

tuttle pulse ratio test
