Exam 2 Flashcards
Shock
Lack of perfusion
Pump problem
cariogenic shock
Cardiogenic shock - History Findings
- massive MI
- dilated cardiomyopathies
- tamponade
- myocarditis
- CHF
- Toxin
Cardiogenic shock - physical exam
pulmonary edema = wet lungs
Cardiogenic shock - treatment
ICU and cardiology
Plumping - pipe problems
Distributive
Types of distributive
septic, neurogenic, anaphylaxis
Septic - history
fever, infection, gram-negative
Septic - physical findings
bounding pulses
Septic - later stages
urine output goes down, pulse quickly goes to crap, body shutting down
Septic - treatment
treat the infection
Neurogenic
- head or cervical or spine injury
- lose of SNS tone to everything below the level of the injury
- poor profusion below injury
Neurogenic - physical findings
bradycardia
Neurogenic - treatment
neurosurgery
Anaphylaxis - history
bee sting, food, penicillin
Anaphylaxis
- IgE cause of initial part of reaction
- airway starting to close down
- kill people is the cardiovascular collapse
- airway is second most common cause of death
Anaphylaxis - physical findings
from anaptyctic shock blood pressure is going to crap
Anaphylaxis - treatment
- epinephrine causes vasodilation
- Benadryl and xanax
- steroids = longer benefit
Fluid problems = not enough
Hypovolemic
Hypovolemic - history
- trauma
- dehydration
- burns
- sweating
- urinating a lot
- vomiting
- diarrhea
- bleeding
- third space in fluids
Hypovolemic - physical findings
- dry lungs
- respiratory rate and heart rate are elevated
Aortic stenosis - common causes
senile degeneration and calcification -calcified after age 65 congenitally bicuspid aortic valve -calcified around age 30 rheumatic fever -commissure calcify in 3rd or 4th decade
Aortic Stenosis
- systolic ejection murmur - throughout
- NARROW pulse pressure
Aortic insufficiency (regurgitation) - common cause - infection
bacterial endocarditis
Aortic insufficiency (regurgitation) - common cause - congenital
bicuspid AoV
Aortic insufficiency (regurgitation) - common cause - increased afterload
systemic hypertension (poorly controlled)
Aortic insufficiency (regurgitation)
- soft high pitched diastolic murmur
- widened pulse pressure
- no beta blockers = increased diastolic time and preload
Mitral stenosis - common cause
-rheumatic valve disease
Mitral stenosis
- opening snap
- low-pitched rumbling diastolic murmur
Mitral stenosis - ECG changes
- left atrial enlargement
- right ventricular hypertrophy
Mitral regurgitation - common cause
- myxomatous changes (MVP)
- rheumatic heart disease
Mitral regurgitation
- mid-systolic click
- pansystolic blowing/harsh murmur
Mitral valve prolapse - common cause
- idiopathic
- Marfan’s
- Ehler’s Danlos
Friction rub, global ST elevation, flu before, chest pain worse with deep breath, chest pain better while leading forward
pericarditis
Muffled heart beat
pericardial effusion
Muffles heart beat, JVD, hypotension
cardiac tamponade
Fixed split A2
ASD
opening snap
mitral stenosis
Mid-systolic click
mitral prolapse with mitral regurgitation
Valve is supposed to be open
stenosis
Valve is supposed to be close
regurgitation
ASD
- fixed S2
- patent foamed ovale (PFO)
VSD - most common
perimembranous - acyanotic congenital heart defect
VSD - auscultation
left lower sternal border
-increase during expiration
AV Canal Defect
40% occurrence in Down syndrome
PDA - auscultation
continuous machinery-like murmur best at LUSB
PDA - treatment
indomethacin
Treatment of valvular issues
surgery
diagnosis of valvular issues
echo
Complications
mitral valve prolapse and bunch of PVCs
-beta-blocker
Pulmonary vascular resistance - fetal to neonatal
goes down
Ductus arteriosus
closes to ligament arteriosus
Foramen ovale
closes to fossa ovale
Terta fallot
- most common cyanotic congenital heart defect
- PROM
- Squatting = increase systemic vascular resistance
- boot-shaped heart
PROM
pulmonic stenosis
right ventricular hypertrophy
overriding aorta
massive/malalinged VSD
Transposition
- parallel circuit
- have to have ASD, PAD, or VSD to sustain life
Keep PAD open
prostaglandins
Close PAD
indomethacin
