Nursing Cardiovascular Assessment

Anatomic Sites of the Cardiac

 

The Heart

  • One day the heart beats 100,000 times , Heart pumps about 2,000 gallons
  • In 70 years the heart beats more than 2.5 billion times
  • Extends from the 2nd to the 5th intercostal space
  • Between the right boarder of the sternum to the lift midclavicular
  • Beats against chest wall to produce apical impulse

Anatomy of the Heart

Anatomy of the Heart

  • Right Ventricle
  • Left Ventricle
  • Right Atrium
  • Left Atrium
  • Superior and Inferior Vena Cava
  • Pulmonary Artery
  • Pulmonary Vein
  • Aorta

 

THREE LAYERS

  • Pericardium
  • Myocardium
  • Endocardium

TWO PUMPS

  • Right side pumps blood to lungs
  • Left side pumps blood to body

FOUR VALVES

  • Two Atrioventricular Valve (AV)

1.Tricuspid Valve (right atrioventricular valve)

2. Mitral (left atrioventricular valve)

  • Two Semilunar Valve (SL)

1. Aortic valve (left semilunar valve)

2. Pulmonary valve (right semilunar valve)

 

Neck Vessels

Neck Vessels

1. Carotid Artery

2. Jugular Veins

  • – Internal
  • – External

 

Circulation

Circulation

What is the order of the flow of blood from the Superior/Inferior Vena Cava to Aorta?

• Superior/Inferior Vena Cava

• Right Atrium

• Tricuspid Valve (right atrioventricular valve)

• Right Ventricle

 

• Pulmonary Valve (right semilunar valve)

• Pulmonary Artery delivers un oxygenated  blood to lungs

• Lungs oxygenate blood

• Pulmonary Vein

• Left Atrium

• Mitral Valve (left atrioventricular valve)

• Left Ventricle ejects blood through aortic valve into aorta

• Aortic Valve (left semilunar valve)

• Aorta delivers oxygenated blood to body

 

Diastole & Systole

DIASTOLE

  • Ventricles are relaxed, AV valves (tricuspid, mitral) open
  • Blood pours rapidly into ventricles
  • Atria contract to push last amount of blood-(pre systole)
  • Bottom number of the B/P

SYSTOLE

  • Mitral and tricuspid valves close, S1 beginning of systole
  • Left ventricular pressure > aortic pressure → aortic valve opens, blood ejected
  • Semilunar valves close (pulmonic and aortic) → S2, end of systole
  • Top number of B/P

 

Conduction

– Sinoatrial node (SA node) – “pacemaker” begin electrical impulse → Atrioventcular node (AV node) → Bundle of His → Bundle branches → ventricles

– ECG- measures electrical impulses

  • P wave : atrial depolarization
  • PR interval: the time from beginning of atrial depolarization to the beginning of ventricular depolarization
  • QRS complex : ventricular depolarization
  • lT wave : ventricular repolarization
  • QT interval : total time for ventricular depolarization and repolarization
  • U wave: may or may not be present ; it follow the T wave , respresnt the final phase of ventricular repolarization

    • Palpate the
    • Carotid
    • Brachial
    • Radial, Ulnar

    • Posterior Tibial
    • Femoral
    • Dorsalis Pedis
  • They should equal (+2). In old age may exhibit weak pulse (+1),pergnant (+3) bounded (look at amplitude pulse )
  •  

    The location of pulse sites on the body

    The carotid pulse is located on the anterior (front) right and left sides of the neck

    • A carotid pulse is normally taken when performing CPR on an adult or child victim.

     

    Radial Pulse and Ulnar Pulse

    The radial pulse is the most common site for taking pulse measurements on adult patients.

    The radial pulse can be easily palpated on the thumb side of the wrist.

     

    Radial Pulse and Ulnar Pulse

     

     

    Brachial Pulse

    Brachial Pulse

    The brachial pulse is located on the inside aspect of the upper arm.

    •The brachial pulse is used for taking an infant’s pulse during CPR.

    •The brachial pulse is also palpated when performing blood pressure on patients.

     

    The femoral pulse is located in the front between the upper leg and the lower hip, where the hip bends.

    It is often used to check circulation of the leg

    femoral pulse

    The dorsalis pedis pulse is found on the anterior (front) side of the foot.

    •The dorsalis pedis pulse is often used to check circulation of the foot.

    The dorsalis pedis pulse

    The posterior tibial pulse is located on the inner ankle area.

    The posterior tibial pulse is often used to assess circulation of the lower leg and foot.

     

    The posterior tibial pulse

     

    The popliteal pulse is located behind the knee

    • The popliteal pulse may be used to check circulation of a patient’s leg or extremity.

    The popliteal pulse

     

    CARDIAC OUTPUT

    A pulse assessment is based on three factors:

    • The Rate of the pulse.

    1. Adults : 60 – 100 beat/minute

    2. Children 90 – 120 beat/minute

    3. Newborns 70 – 170 beat/minute

    4. < normal = bradycardia

    5. > normal = tachycardia

    • The Rhythm of the pulse: ( regular or irregular)
    • The Force (Strength) of the pulse.

    1. force measures the volume of blood flow.

    2. weak indicate reduced volume of blood flow as in the condition of shock )

     

    Cardiac Output

    Blood Pressure

    Systolic maximum pressure exerted on arterial wall during ventricular contraction.

    • Diastolic pressure in vasculature during ventricular relaxation .
    • Children vary with age

     

    Blood Pressure Classification in Adults

    Category

    Systolic

    Diastolic

    Normal

    <130

    <85

    High Normal

    130-139

    85-89

    Mild Hypertension

    140-159

    90-99

    Moderate Hypertension

    160-179

    Severe Hypertension

    180-209

    110-119

    Crisis Hypertension

    >210

    >120

    Hypertension

    1.Secondary means cause is known may be a side-effect of medication

    2.Primary Hypertension means cause is unknown

    Hypotension

    • Late sign of hypovolemia, cardiac failure, shock
    • 90 / 60 common in young females
    • Hypotension Lead to inadequate perfusion in vital organs such as heart, brain and kidney

     

    Two factors determine blood pressure

    • Cardiac output = stroke volume x heart rate
    • Systemic vascular resistance (SVR)

    Stroke Volume determine by

    1. Preload = filling volume of ventricles

    2. Contractility = force of muscle contraction

    3. Afterload = resistance ventricles contract against

     

    Pulse Pressure

    • Systolic – Diastolic
    • Normal 35 – 40 mmHg
    • < 30 mmHg pulse hard to detect
    • Decreasing pulse pressure early sign of inadequate circulating blood volume

     

    Palpation

    Palpation

    • Pericardium palpation: When palpation the pericardium used the pads of figures because especially sensitivity to vibration and can affect in large pulse site.
    • Place the palm of your hand over the left 4th, 5th, and 6th ICS along the midclavicular line to locate the apical impulse.
    • Systemic palpation that cover the sternoclavicular , aorta , pulomonic,
    • right ventricular , left ventricular (apical) and epigastric area, Apical pulse area.
    • Palpate apical impulse
    • Using 1 finger locate the apical impulse
    • Ask client to “exhale and hold”=aids in locating pulsation
    • May need to turn client to left to find it.
    • – Note: Location, size, amplitude and Duration
    • Apical impulse palpable in ½ adults, and not in obese or thick wall clients.
    • Apical impulse increases in amplitude and duration in client with anxiety, fever, hyperthyroidism and anemia

    Palpation

     

    Percussion

    • Percussion: outline of the heart’s boarder; limited with the female breast tissue or in an obese person or person with muscular chest wall.
    • Used to detect the approximate location of the left cardiac border.
    • Place the pleximeter finger of your nondominant hand parallel to the third left intercostal space just medial to the midclavicular line.
    • Percuss lightly from lateral resonance to medial dullness.
    • Note the precise location at which the percussion note changes to dullness.
    • Repeat the examination at the 4th and 5th left intercostal spaces.
    • Note the distance between the percussion note change and the midsternal line to provide a rough estimate of cardiac size.
    • Notes : Chest X ray more exact information about heart size ( some pt have lung disease which reduce the accuracy of percussion).

     

    Auscultation

    • Sound is transmitted in direction of blood flow, so specific sounds are best heard over areas where blood flows after it passes through a valve
    • Client supine with head slightly elevated, stand at right side in a quiet room (concentrated listening)
    • Begin by identifying S1 & S2
    • Palpate carotid while auscultating the heart
    • Carotid pulsation & S1 are synonymous
    • Rate, rhythm, and heart sounds
    • The diaphragm is used for listening to higher-pitched sounds, such as normal heart sounds as it is applied tightly against the chest wall.
    • The bell is used to listen to lower-pitched sounds such as additional heart sounds and some murmurs. It should be applied lightly to the chest wall.
    • Auscultating the apical pulse with the diaphragm to evaluate cardiac rate and rhythm.
    • Count the number of beats that occur in 15 seconds, if the rhythm is regular. If the rhythm is irregular, listen for a full 60 seconds to count heart rate.
    • Also note if the rhythm pattern is regularly irregular, or if there is no distinguishable pattern.

    • Pressure is applied over the ulnar and the radial arteries so as to occlude both of them.
    • Still elevated, the hand is then opened. It should appear blanched (pallor can be observed at the finger nails.

    Result

    • Normally: Ulnar pressure is released and the color should return in 7 seconds.
    • Abnormal If color does not return or returns after 7-10 seconds, then the ulnar artery supply to the hand is not sufficient .
    • Risk for hand ischemia
    • Radial vessel spasm

     

    2. Venous Jugular Distension

    Due to venous congestion (CHF)
