Flashcards in Heart Lab Deck (37):
1

Which heart sound? Produced in the beginning of systole when the AV valve closes and the SL valves open

Lub sound

1st heart sound

2

Which heart sound? Occurs after the rapid fillings of the ventricles after the AV valves open

3rd heart sound

3

4 major ausculatory areas

1. Aortic area
2. Tricuspid area
3. Pulmonary area
4. Mitral area

4

Pressure exerted by the blood against the vessel walls

Blood pressure

5

The recording of the vibration sounds

Phonocardium

6

Which heart sound? Occurs at the time of atrial contraction. Do to rush of blood into the ventricles

4th heart sound

7

Which heart sound? Occurs at the end of systole and caused by the closure of the SL valves and the opening of the AV valves

DUB sound

2nd Heart sound

8

Area on the chest where the sounds from each valve can be heard most clearly

Ausculatory area

9

Highest pressure in the artery-produced during the hearts contraction

Systolic BP

10

Normal systolic BP

120 mmHg

11

Most commonly measured BP

Atrial pressure

12

Lowest pressure in the artery-produced during the hearts relaxation phase

Diastolic pressure

13

Normal diastolic BP

80mmHg

14

Pulse pressure formula

SP-DP

15

Normal pulse pressure

40 mmHg

16

Mean BP formulas

DP + 1/3(pulse pressure)

(Cardiac output)(total peripheral resistance)

17

Cardiac output equation

(Heart rate)(stroke volume)

18

Direct method to measure BP

A cannula is inserted into the artery and BP is measured with a transducer or mercury manometer

19

Indirect method to measure BP

With a stethoscope

Ausculatory and palpatory meathid

20

TPR=

Total peripheral resistance

21

Normal mean BP

96-100 mmHg

22

Normal reflex in response to a cold stimulus

Increase in BP

23

Indirect method where cuff is used and pressure is FELT

Palpatory method

24

Indirect method where cuff and stethoscope are used

Auscultatory method

25

4 phases of sounds heard through the stethoscope as pressure decreases during the auscultatory method

Korortkow sounds

26

Why can children survive longer in cold water than adults?

More dramatic mammalian dive reflex

27

TPR equation

((Systolic + 2diastolic)/3)
-------------------------------------
Pulse pressure x HR

28

Normal systolic increase to cold stimulus

10 mmHg

29

Hypertensive systolic increase to cold stimulus

30-40 mmHg

30

Reflex to cold water on the face

Mammalian dive reflex

31

Formula to determine number of steps required to obtain s 2.5 pulse ratio

=S1 + (S2-S1)(2.5-r1)
----------------------------
(r2-r1)

Steps in test 1 + (steps in test 2 - steps in test 1)(2.5-pulse ratio 1)
----------------------------------------------------------------------------------------
(Ratio 2 -Ratio 1)

32

Physiological effects of mamalian dive reflex

Decrease human heart rate 10-25%
Peripheral vasoconstriction of capillaries of the extremities

33

Index of physical fitness formula

Duration if exercise (s) x 100
---------------------------------------------
2(sum of 3 pulse counts in recovery)

34

Test based on the observation that a less fit person will have a higher pulse then a normal person for the same number of steps

Tuttle pulse ratio test

35

Total number of pulse beats counted for one minute

Tuttles pulse ratio

36

Determined by the amount of exercise required to obtain s 2.5 pulse ratio

Cardiovascular efficiency

37

Specific gravity of blood

1.056
