27
What is perfusion?
The flow of blood through arteries and capillaries which delivers nutrients and oxygen to cells
28
What is an artery?
Arteries take oxygenated blood from the heart and deliver it to organs
29
What are veins?
Veins take de-oxygenated blood from organs to the heart
30
What are capillaries?
Tiny vessels that connect arteries and veins
31
What is ischemia?
Blood flow is restricted, therefore oxygen is restricted
32
What is an infarction?
Death of tissue resulting from a lack of blood supply, typically caused by obstruction or clot
33

36
What is the typical first warning sign of congenital heart defects?
Abnormal oxygen sat level
37
What are the two rules of hemodynamics?
Blood flows from high pressure areas to low pressure areas. Blood takes the path of least resistance
38
What are the three obstructive congenital heart defects?
Aortic Senosis: narrowing of entrance to pulmonary artery Pulmonic stenosis: narrowing of entrance to pulmonary artery (blood mixes in the artery) Coarctation of Aorta: Localized narrowing near insertion of ductus arteriosus
39
What are the four mixed congenital heart defects?
Transposition of great arteries: pulmonary artery and aorta are switched, no communication between systemic and pulmonary circulation. Life threatening, requires surgery. Hypoplastic left heart syndrome: underdevelopment of the left side of the heart. Blood mixes between oxygenated and deoxygenated, palliative care or patient needs a new heart. Total anomalous pulmonary venous connection: failure of pulmonary veins to join left atrium. Needs surgery Truncus Arteriosus: single semilunar valve instead of two. Needs surgery
40
What are the decreased pulmonary blood flow causing congenital heart defects?
Tetralogy of fallot: ventricular septal defect, pulmonic stenosis, overriding aorta, right vent hypertrophy. Blood is shunting left to right. Cyanosis noted, may be instinctively squatting to increase aortic pressure. Tricuspid Atresia: Tricuspid valve fails to develop. Can be managed by meds, may need surgery
41
What congenital heart defects increase blood flow?
Atrioventricular canal defect: two septum defects, more common in people with Down syndrome. Patent ductus ateriosus: duct fails to close when you’re born or a few days later, left untreated child will have shorter lifespan. Atrial septal defect: abnormal opening between atrial, usually symptomatic at 20-30 years own. Can close on its own unless it grows Ventricular septal defect: most prominent congenital heart disease.
42
What is the most prominent congenital heart defect?
Ventricular septal defect
43
What are the symptoms of increased blood flow heart defects?
Tachycardia, tachypnea, murmur, CHF, poor weight gain, diaphoresis, periorbital edema, respiratory infections
44
What are symptoms of decreased blood flow heart defects?
Cyanosis, poor weight gain, polycythemia
45
What are symptoms of mixed congenital heart defects?
Cyanosis, poor weight gain, pulmonary congestion, CHF
46
What are symptoms of obstructed heart defects?
Diminished pulses, poor colour, delayed cap refil, decreased urine output, CHF, pulmonary edema
47
How do Ventricular Septal Defects present?
Fatigue, low level of consciousness, edema, murmur, CHF. In babes they can sweat while eating, struggle to thrive, high HR and RR.
48
How are you ventricular septal defects diagnosed?
Chest X-ray showing increased pulmonary vascular markings. Echocardiograms identifying multiple VSD’s and direction of shunting. When VSD is severe it can reverse shunting.
49
What occurs during severe VSD?
More blood pools in the right ventricle, right ventricle pressure increases and exceeds left pressure. Shunt direction is reversed, deoxygenated blood is delivered to tissues and organs.
50
What is Digoxin?
A medication used in heart failure that increases contractility, decreases heart rate. Have to monitor pulse for one full minute prior to administration. Look for signs of toxicity and potassium levels.

52
What are the steps in clinical judgment?
Noticing —> Interpreting —> Responding —> Reflecting
53
Is clinical judgement always required?
No, clinical judgement isnt always required to know appropriate care, it does take clinical judgement to recognize abnormal findings and take action.
54
