Lecture 2: Cardiovascular and Peripheral Vascular Flashcards
(43 cards)
CV: Heart Valves: Atrioventricular
Between the atria and the ventricles
- Tricuspid opens from RA to RV
- Mitral opens from LA to LV
CV: Heart Valves: Semilunar
- Pulmonic valve and aortic valve
CV: 2 Neck Vessels
- Carotid Artery
- Jugular Artery
- Internal
- External
- Venous pulse and pressure
Cardiovascular Assessment Subjective Data: Health History
- Chest pain
- Dyspnea
- Orthopnea
- Cough
- Fatigue
- Cyanosis or pallor
- Edema
- Nocturia
- Past cardiac history
- Family cardiac history
- Personal habits (cardiac risk factors)
Cardiovascular Assessment Subjective Data: Cultural and Social Considerations
- Increase incidence of cardiovascular disease (CVD) in Canada among men and women
- Influence of socioeconomic factors
- High blood pressure
- Smoking
- Serum Cholesterol
- Obesity
- Diabetes
CV: Nonmodifiable Risk Factors
- Age
- Gender
- Genetic Factors
- Race and Ethnicity
CV: Modifiable Risk Factors
- High BP
- Smoking
- Diabetes mellitus
- Physical inactivity
- Obesity
- High blood cholesterol
CV: Additional Health History Questions: Infants
- Maternal Health
- Feeding without tiring
- Growth
- Activity, milestones
CV: Additional Health History Questions: Children
- Growth
- Activity
- Joint pain and fever
- Headache and nosebleed
- Resp disease
- Family history
CV: Additional Health History Questions: Pregnant women
- Hypotension
- Hypertension
CV: Additional Health History Questions: Older Adults
- Disease
- Medication
- Environment
CV: Women and Heart Attacks
- Symptoms easily attributed as something else
- Often ignored
- Women minimize significance of symptoms
- Heart disease is the leading cause of death in women older than 55 yrs of age
- Ovaries decrease production of estrogen = increased low-density lipoprotein (LDL), blood pressure (BP), and body fat above the waist, decreased high-density lipoprotein (HDL), metabolism of sugar affected
- Hormone replacement therapy (HRT) or no HRT?
CV Physical exam: Palpate and auscultate carotid artery while pt. sitting #1
- Inspection
- Palpation
- Percussion
- Auscultation
1. Palpate carotid arteries while cient sitting, and auscultate for bruit
2. Assist client to supine position: - Inspect the anterior chest - deformities, pulsations, skin
- Palpate the apical impulse
- Palpate for thrills
- Repeat in L lateral position
3. Precordium - Inspect the anterior chest
- Palpate the apical impulse
- Palpate across the precordium
- (Precuss to outline the cardiac borders)
CV: Landmarking the chest
- Intercostal spaces
- Midclavicular lines
- Sternal border
- Axillary lines
CV: Auscultation of CV and PV
- Identity auscultatory areas. Use the diaphragm of stethoscope
- Note rhythm and rate
- Identify S1 and S2 (S1 is louder than S2 at the apex, S1 coincides with carotid artery pulse)
- Listen to S1 and S2 separately. Closure of valves produces sound
- Listen for extra heart sounds, murmurs
Where?
- 2nd ICS, RSB (aortic)
- 2nd ICS, LSB (pulmonic)
- 5th ICS, LSB (tricuspid)
- 5th ICS, LMCL (mitral)
Auscultatory Areas: APe To Man
CV: What is S1?
1. What valves are closing?
2. Location
3. Cardiac cycle
4. Sound
- Tricuspid and mitral
- Apex
- Beginning of Systole
- LUB-dup
CV: What is S2?
1. What valves are closing?
2. Location
3. Cardiac cycle
4. Sound
- Pulmonic and aortic
- Base
- End of Systole
- Lub-DUP
CV: Split S2
- Normal occurrence at end of inspiration
- Inspiration -> aortic closes before pulmonic
- DUP becomes T-DUP
- Expiration -> aortic and pulmonic valves close together
- Usually heard in pulmonic valve areas
CV: What are murmurs?
- Blowing/Swooshing sound from turbulent blood flow
- Innocent
- Normal in healthy children and adolescents
- Functional
- From increased blood flow in the heart - Pathological
- Valvular defect -> stenosis or regurgitation - Frequently found with a thrill
- Repeat auscultation with pt. in L lateral position
CV Physical Exam - Murmurs
- Timing
- Loudness
- Pitch
- Pattern
- Quality
- Location
- Radiation
- Posture
CV Extra Heart Sounds
- After listening to S1, S2, and murmurs
- Bell at LLSB an apex in L lateral position
- Filling sounds -> extra heart sounds
- 3rd Heart sound, S3
- Soft, dull, low-pitched after S2
- Normal (physiological) children/young adults
- Pathological in older adults
- Ventricles resistant to filling - 4th Heart Sound, S4
- Very soft, low-pitched, just before S1
- Atria contract against resistant ventricles (CHF, MI)
- May be normal in adults after exercise
- R sided S4 LLSB; L sided S4 at apex - Summation Gallop S4, S1, S2, S3 together
- Pericardial friction rub
CV Developmental Considerations: Infants
- Diff. in apical, radial pulses
- Normal heart rates
- Murmurs more common in 1st days
CV Developmental Considerations: Children
- Position of apical impulse
- Venous hum
- Innocent heart murmurs
CV Developmental Considerations: Pregnant women
- Changes in BP (varies with position)
- Heart sound changes from increased blood volume and workload
