Q

During contraction, what happens with the apex?

Q

What do the pulmonary veins do?

What does the aorta do?

A

Pulmonary veins. return freshly oxygenated blood to the left side of the heart, while the aorta carries it out of the body.

Q

Compliance of lung and cardiac tissue?

A

It’s ability to stretch and be elastic, allowing the tissue to accommodate what it needs to do.

Q

Where does the cardiac impulse originate? Explain its travel

A

Originates in the sinoatrial node (SA node), intrinsic rhythm.
Travels to the trail ventricular node.
Travels to the bundle of His, the right and left bundle branches
Then to the ventricles

Q

Pulse locations?

A

Carotid, brachial, radial, femoral, popliteal, dorsalis pedis, posterior tibial

17
Q

Apical pulse ranges?

A

Normal: 50-95
Brachycardia: <50
Tachycahrdia: >100

18
Q

Hypertension and hypotension?

A

Hyper: greater than 140/90
Hypo: Systolic less than 100, decreased cardiac output

19
Q

Cardiac output formula

A

SV x HR

20
Q

Heart sounds/ S1/S2?

A

First: Systole. AV valves/Mitral and tricuspid valves shut (S1). Loudest at the apex. Lub.
Second: End of systole. SL valves/Aortic and pulmonic valves open (S2). Loudest as the base. Dub.

21
Q

Abnormal S3 heart sounds?

A

Vibration of the ventricles that resist early, rapid filling

22
Q

Abnormal S4 heart sounds?

A

Vibration of the ventricles the occurs when the atria contract and push blood into a noncompliant ventricle.

23
Q

Explain murmurs?

A

Increases or decreases in the velocity of blood flow. Structural defects in the valves or unusual openings in the chambers.

24
Q

Auscultatory areas of the valves?

A

Aortic: 2nd right interspace
Pulmonic: 2nd left sternal interspace
Erbs’s point/second pulmonic: 3rd left sternal interspace
Tricuspid: 4th interspace left lower sternal border
Mitral: 5th interspace at left clavicular midline

25
Q

Typical heart rate of infants?

A

Younger the age, the higher the heart rate
70-90 when sleeping
170 when crying

26
Q

Brady and tachycardia in infants?

A

Bradycardia: <90 bpm in newborns. <60 bpm in older infants and children.
Tachycardia: >200 bpm in newborns. >150 bpm in infants

27
Q

Variations that may be found in pregnant women?

A

Higher resting pulse.Drop in BP during second trimester and a rise in third trimester. Heart sounds are different because of increased blood volume. Edema.

28
Q

Variations that may be found in older adults?

A

Gradual rise of SBP, DBP constant. RF orthostatic hypotension. Premature ectopic beats on ECG.
Be careful palpating carotid pulse because can accidentally lower the heart rate.

29
Q

104F
98.6F
95F

A

40C
37C
35C

30
Q

With every beat the heart pumps an amount of blood into the aorta. Volume?

A

Stroke volume

About 70 mL in the adult.

31
Q

The heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration.

A

Sinus arrhythmia.
Inspiration momentarily causes a decreased stroke volume from the left side of the heart; to compensate the heart rate increases.

32
Q

The maximum pressure felt on the artery during left ventricular contraction, or what?

A

Systolic pressure.

Left ventricular contraction is systole

33
Q

The elastic recoil, or resting, pressure that the blood exerts constantly between each contraction.

A

Diastolic pressure

34
Q

The difference between the systolic and diastolic pressures, reflecting the stroke volume.

A

Pulse pressure

35
Q

The pressure forcing blood into the tissues average over the cardiac cycle.

A

Mean arterial pressure or MAP

It’s a value closer to diastolic pressure plus one third of the pulse pressure

36
Q

What five things is the blood pressure determined by?

A

Cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, elasticity of vessel walls

37
Q

A tough, fibrous, double-walled sac that surrounds and protects the heart.
The muscular wall of the heart.
The thin layer of endothelial tissue that lines the inner surface of the heart chambers and valves.

A

Pericardium
Myocardium
Endocardium

38
Q

Abnormally high pressure in the left side of the heart gives a person symptoms of what?

A

Pulmonary congestion

39
Q

Abnormally high pressure in the right side of the heart shows symptoms of?

A

Distended neck veins and abdomen
