Module 5: Cardiovascular And Pain Flashcards
What to look for when doing a lower extremity evaluation?
- Vascularity and Color (lower extremities tend to have less circulation)
- Inspect for Open areas or Ulcers
- Identify varicosities and assess location
- Inspect for pitting or non-pitting edema
- presence or not of hair on lower extremities
- Check for tenderness, pain, and erythema
- CMS
- Capillary refill in toes (brisk in 3 second return)
When looking at lower extremity open areas and ulcers, what should you check for?
Location, time being there, wounds, and bad perfusion leading to not even noticing its there
TED Stockings
compression stockings that prevent blood clots and aid in cardiovascular/peripheral vascular disease and varicosities
Anti Embolic Stockings
prevent pooling in lower extremities
When is the best time to put on compression stockings?
When the feet have been up for 30 minutes / when they wake up before leaving bed
NEVER use TED Stockings on …
patients with PAD (Peripheral Arterial Disease)
Pitting Edema
pushing down on an edem and seeing how long the indentation lasts - then rated on severity
No hair on lower extremities indicates?
poor circulation, and shiny skin indicated atrophy of the skin there
Deep vein thrombosis
in lower extremity area, can be palpated for warmth and swelling, and pain/inflammation/redness
CMS
“Circulation, Movement, Sensation”
Check for capillary refill in 3 seconds, can they move their toes, can they ID what toe you touch
Cardiovascular System
the heart and peripheral extremities - pump for circulation to and from the heart throughout the body through veins and arteries
Pericardium
tough, loose fitting, fiber sac that attaches to the great vessel and surrounds the OUTERmost layer and surrounds the heart
Epicardium
thin OUTERmost layer of the heart
Myocardium
thick muscular MIDDLE layer of the heart
Endocardium
thin layer of endothelial tissue that forms the INNER most layer of the heart
How many chambers are in the heart?
4
Two upper heart chambers
- left and right atria at the base of the heart
- earlike shape
- thin walled, reservoirs for returning blood from the veins
Two lower heart chambers
- right and left ventricles, at the apex
- thick walled and pumps the blood to the lungs and throughout the body
Which chamber pumps blood into the body?
Left Ventricle
Left Heart
the left atrium and ventricle
Right Heart
right atrium and ventricle
Cardiac Septum
tight partition dividing the left and right hearts
1 Way Valves
- directs the flow of blood
- AV and Semilunar Valves
Atrioventricular Valves (AV)
- Tricuspid (right; 3 cusp) and Mitral (left; 2 cusp; bicuspid) Valves
- between atrium and ventricles
Semilunar Valves
- Pulmonic and Aortic Valves
- between ventricles and great vessel / organ system
Arteries
carries oxygenated blood from the heart to the body
carries blood AWAY from the heart
Veins
carries deoxygenated blood TOWARDS the heart
Pulmonary circulation
Right heart pumps deoxygenated blood to the lungs
Systematic Circulation
Left heart pumps oxygenated blood to rest of the body
Direction of Blood Flow
Vena Cava –> R Atrium –> Tricuspid Valve –> R Ventricle –> Pulmonic Valve –> Pulmonary Arteries –> Lungs –> Pulmonary Veins –> L Atrium –> Mitral Valve –> L Ventricle –> Aortic Valve –> Aorta –> Body Systems –> repeat
Sinoatrial Node (SA Node)
- hearts “pacemaker”
- generates electricity and travels through the cardiac circuit
- in R atrium near the superior vena cava
Atrioventricular Node
- R atrium near the AV valve
- delays passage of electrical impulses from SA node to the ventricles to make sure the atria have ejected all the blood to the ventricles before ventricles contract
Bundle of HIS
passes electrical impulses from AV node to Purkinje fibers that then move back up the heart
Flow of Heart Conduction
SA node –> AV node – > Bundle of His –> Purkinje fibers
ECG
composite recording of all actions and cells of the myocardium (waves and segments of the heart)
P Wave
SA node fires and depolarizes when atria are full. Atrial contractions start 100 msec after, represented by P-Q waves
Q Wave
depolarization occurance
R Wave
wave from ventricle contraction
S Wave
repolarization occurrence; plateau in action potential when ventricles contract
T Wave
ventricular repolarization right before this wave
Systole
- contraction / work phase
- semilunar valves open
- AV valves closed
- S1 best heard at APEX “LUB”
Diastole
- relaxation phase
- when blood fills the ventricles
- AV Valves open
- Aortic valve closed
- S2 Best heart at the BASE “DUB”
Where on the heart is S1 best heard?
at the apex (5th intercostal)
Where on the heart is S2 best heard?
at the base
When taking the subjective part of the cardiovascular health history, make sure to ask the …
Chief complaint
ex: pain - COLDSPA dyspnea on exertion or at rest palpitations dizziness medications edema nocturia
When looking at the health assessment of a cardiovascular health history you must gather?
Chief complaints
Personal/Lifestyle Health practices
Past (personal) medical history
Risk factors
Men have higher cardiovascular issue rates until when…
when women are post-menopause
Hypernatremia
high sodium levels
High lipid levels are linked to
increased likelihood of cardiac event
Order of Physical Exam Techniques used in Cardiovascular Assessment?
- Inspection
- Palpation
- Auscultation
Cardiovascular Inspection
- move cephalocaudally in 3 positions
- look for pallor, cyanosis, vital signs, HR, heaves, smell, cough, edema, varicosities, symmetry, deformities, pulsations
3 Positions to do Physical Cardiovascular Assessment?
- Sitting
- Supine (30-45 degree angle)
- Left Lateral Recumbent
5 Important Areas of the Heart
Aortic (ALL) Pulmonic (PEOPLE) Erbs Point (ENJOY) Tricuspid (TIME) Mitral (MAGAZINE)
PMI
point of maximal impulse/apical impulse (mitral area)
Where might you be most likely to see a visible impulse on the chest?
5th intercostal or medial space (left side) (especially in thin people)
Aortic Area location
2nd ICS, right Sternal Border
Pulmonic Area Location
2nd ICS, left sternal border
Erbs Point Location
3rd ICS, left sternal border
Tricuspid Area Location
5th ICS (4th in children), left sternal border
Mitral Area Location
Mid-clavicular, left side, 5th ICS - maximal impulse
