What can effect respiration?
inspiration may cause a split S2
S1
- Right atrium is filling

“Tenessee”
Gallop
When does S3 occur?
- early in diastole
- immediately after S2
- at the very end
Pathological Reasons for Listening for S3
- Anemia,
- sign of HF
- Volume overload
- hyperthyroidism

- renal failure
- persists when sitting up
When does S4 occur
- End of diastole
- prestyole
- when ventricle is resistant to filling, just before S1
Where is S4 best heard
apex, left lateral position (left sided
Reasons for listenting for S4
- decreased compliance of ventricle
- systolic overload
- aortic stenosis
- systemic hypertension
Lifestyle that can affect heart
- Smoking
- Inactivity
- Sitting a lot
- Nutrition
How are murmurs graded?
1-4
What does a murmur sound like?
- washing machine
What are reasons for having a murmur
- During menstrual cycle (benign)
- During Exercise
- Thyroid level too high
- Anemia (low blood)-less rbcs, less oxygen
- expected for infants
- structural defects in valve
- unusual openings in chambers
What are you assessing for in heart sounds
- pitch
- volume/intensity
- duration
- timing- Sys, Dia
- noting you heard S1 & S2
Cardiac Output Formula =
- SV X HR
What is a resting adult CO
4-6 of blood/min
What is preload?
force of stretch in heart from venous return
What is afterload?
Ventricular pressure needed to eject blood
What are the neck vessels
- carotid artery
- jugular veins
What is important about carotid artery pulses
- pulse goes along with S1, nsync
What do the neck vessels say about the heart (carotid, jugular) p.473
how well the heart is functioning
What happens to the neck vessels when lying down vs sitting up
- sitting you can see it
- sitting up it goes away
What happens heart/neck when Aging?
- BP increases
- lifestyles
- sodium
- Left ventricle increases
- Increase Arrhythmias
- Orthostatic Hypotension (getting out of bed fast)
- check for bruits in carotid
- systolic heart murmurs
Where do you assess an adult heart
5th intercostal
Where do you assess an infant’s heart?
3-4 intercostal
What is PMI referring to?
- Point of Maximal Impulse
- Where to assess
- Mitral Area
High risk factos for heart disease
- high blood pressure
- smoking
- high cholesterol
- diabetes
- obesity
What protects the heart for women?
estrogen
How does obesity affect Cardiovascular Disease?
- fat around the organs (stomach)
*
What are you assess for objective data
- room prep
- position and draping
- equipment needed
what type of assessment do you take for bruit?
auscultate
What type of assessment do you take for carotid arteries?
palpate
What is difficult to see in healthy people related to the heart?
jugular veins
What type of assessment do you take for the Precordium
inspect, palpate (PMI), percussion (not reliable)
All patients take meds Mneumonic
- Aortic Valve
- Pulmonic Valve
- Tricuspid Valve
- Mitral Valve
What do blood vessels do?
Transport Blood which transports oxygen
What do lymphs do?
- Helps vessels control fluid,
- gets rid of waste.
- Immunity.
What are you markers for major arteries?
ulnar, radial, brachial
When feeling pedal pulses what artery?
- femoral
- politeal
- posterior tibial
- doral pedis (top of foot)
What are signs getting good blood flow?
- Cap refill less that 3
- Warmth
Intraluminal valves help to ensure
blood moves towards the heart
What do varicose veins look like?
- blue
