Q

Jugular Veins

A

empty unoxygenated blood directly into the superior vena cava –> no cardiac valve separates the vena cava and the right atrium, so the jugular veins can give information on the activity of the right side of the heart

Q

The Cardiac Cycle

A
  1. Diastole - the period of ventricular filling, two phases:
    a. protodiastole - passive
    filling of the ventricles
    (75% CO)
    b. presystole - atria contract
    to push remaining 25%
    of CO into ventricles
  2. Systole - contraction of the ventricles

Q

Auscultation of the Carotid Artery

A

keeping the neck in a neutral position, auscultate 3 points:
1. angle of the jaw
2. midcervical area
3. base of the neck
ask the patient to take a breath, breathe out, and hold briefly for best results

—> ALWAYS done prior to palpating to look for the presence of a bruit

Q

Palpation of the Carotid Artery

A

palpate each carotid artery medial to the sternomastoid muscle in the neck
- note the contour, amplitude
of the pulse and presence
bilaterally

–> NEVER palpate both at the same time

Q

Central Venous Pressure (CVP)

A

Jugular Venous Pressure can be used to assess central venous pressure (indicates the heart’s efficiency)
- the internal (right) jugular
vein is best (not visible but
pulse is palpable

19
Q

Calculation of JVP

A
  1. patient suprine, HOB 45 degrees and head turned away
  2. place ruler 1 perpendicular to angle of louis
  3. place ruler 2 at the highest point of jugular pulsation
  4. JVP = intersection point
20
Q

JVP of <2cm

A

normal

21
Q

JVP of >2 cm

A

elevated, requires additional testing

22
Q

Abdominojugular Test

A

performed when JVP calculation indicates an elevated pressure (>2) to confirm

  1. patient supine
  2. push RUQ in (on liver) for 30 sec –> fluid from the liver will cause the jugular vein to rise
    • if the vein rises and falls
      when pressure is released
      = normal
    • if the vein rises, but it does
      not fall immediately when
      pressure is released =
      elevated JVP confirmed
23
Q

Inspection of the Anterior Chest

A

inspect for visible pulsations of the apical impulse at the level of the 4th or 5th intercostal space (inside the midclavicular line)

24
Q

Palpation of the Apical Impulse

A

position the patient supine and locate the apical impulse using one finger pad –> ask the patient to exhale and hold
- if the impulse cannot be felt
when supine, rotate the
patient midway to the left
–> this will displace the
impulse further left

Note:
- location of the impulse
- the size of the impulse
- amplitude
- duration

25
Q

Palpation Across the Precordium

A

with the patient lying supine, use the palmar aspects of the four fingers to gently palpate over the apex, left sternal border, and the base
–> intended to identify the
presence of (if any)
additional or abnormal
pulsations (ex. thrills)

26
Q

Thrill

A

a palpable vibration signifying the presence of turbulent blood flow, accompanies a loud murmur

Note:
- if a thrill is present
- location
- timing during the cardiac cycle

27
Q

Auscultation Points

A

the regions in which sounds produced by the valves are best heard

Note:
- rate and rhythm, irregularities
- Identify S1 and S2 seperately
- extra heart sounds
- murmurs

28
Q

Normal Heart Sounds

A

S1 and S2

29
Q

S1

A

occurs with the closure of the AV valves (tricuspid and mitral)
- occurs when the pressure
within the ventricles
exceeds that of the atria,
closing the AV valves
- signals the beginning of
systole

30
Q

S2

A

occurs with the closure of the semilunar valves (aortic and pulmonary)
- occurs when the pressure
inside the atria and
pulmonary arteries exceed
that of the ventricles,
forcing the valves shut
- signals the end of systole

31
Q

Abnormal Heart Sounds

A

S3, S4, and murmurs

32
Q

S3

A

occurs when the ventricles are resistant to filling during protodiastole (passive filing)
- present immediately after
S2

ventricles have just contracted (S2) and are ready to passively fill (protodiastole)

33
Q

S4

A

occur when the ventricles are resistant to filling during prediastole (active filling, atrial contraction)
- present just before S1

ventricles have contracted (S2) and have passively filled, and are ready for presystole to occur to finish filling (just prior to S1)

34
Q

Murmurs

A

conditions resulting in turbulence of blood flow –> creates a gentle, blowing, swooshing type sound that can be heard all over the chest wall

35
Q

Conditions resulting in murmurs (3)

A
  1. increases in velocity of blood (blood flows faster)
  2. Decreases in viscosity of blood (blood is thinner, thus can move faster)
  3. Structural defects in the vales or unusual openings in the chambers (causes blood to circulate inefficiently)
36
Q

Heart Failure

A

occurs when the heart cannot pump blood efficiently, cannot meet the body’s metabolic needs

37
Q

Aortic Stenosis

A

Calcification of the aortic valve does not allow it to open properly, restricting the forward flow of blood during systole
- results in hypertrophy of the
LV (needs more muscle to
overcome stenosis)
- S2 split if valve is thicker
- apical pulse displaced left
(LV hypertrophy pushes it)
- thrill present

38
Q

Mitral Stenosis

A

calcified mitral valve does not open properly, restricting the forward flow of blood during diastole
- results in the enlargement
of LA (accommodate
increased blood volume
and pressure)
- pulmonary congestion +
edema, orthopnea, SOBE
(fluid backflow into lungs
- thrill present

39
Q

Aortic Regurgitation

A

incompetent aortic valve doesn’t close, blood flows back into LV during diastole
- results in hypertrophy of the
LV (needs more muscle to
overcome stenosis)
- results in the dilation of LV
(to accommodate inc blood
volume)
- angina
- displaced apical impulse
- BP increased (increased
resistance, blood volume)
- murmur during S2 (doesn’t
fully close when systole
finishes, some turbulence
present)

40
Q

Mitral Regurgitation

A

incompetent mitral valve doesn’t close, blood flows back into LA during systole
- results in hypertrophy of the
LV (needs more muscle to
overcome stenosis)
- results in the dilation of LV
(to accommodate inc blood
volume)
- angina
- displaced apical impulse
- murmur during S1 (doesn’t
fulling close for systole,
some turbulence present)

41
Q

Older Adult Considerations: Anatomical Changes

A
  • systolic BP increases
  • diastolic BP decreases
  • LV thickens (compensation
    mechanism for stiffening
    vessels and increased
    resistance)
  • inability to meet CO needs
    during exercise (SOBOE)
  • increase in ectopic beats
  • ECG changes (prolonged P-R
    interval and Q-T intervals)
  • presence of supraventricular/
    ventricular arrythmias
42
Q

Older Adult Considerations: Health History

A
  • history of pulmonary OR heart disease
  • taking medications
  • home environment assessment (could anything exacerbate symptoms? affect AODL?)
43
Q

Older Adult Considerations: Physical Exam

A
  • gradual rise in systole BP with age
  • sensitive carotid artery
  • chest dize increases in anterio-posterior diameter
    = harder to palpate apical
    impulse
    = difficult to hear S2 split
  • S4 increasingly common
  • systolic murmurs common
    -ectopic beats common
