Cardiovascular Emergencies Flashcards
(53 cards)
What is the flow of blood through the heart?
RA > RV > Lungs > LA > LV
What is arteriosclerosis?
thickening/hardening of vessel wall
What is atherosclerosis?
buildup of plaque inside of the vessels
What is plaque?
adipose tissue depositis
What are 2 cardiac diseases that can contribute to atherosclerosis?
HTN and hypercholesterolemia
What can a complete obstruction of the coronary artery lead to?
myocardial infarction
How many coronary arteries are there?
4
In what part of the contraction cycle do the coronary arteries fill up with blood?
diastole
What 3 bad habits/lifestyles can contribute to acute coronary syndromes?
smoking | obesity | alcohol abuse
What is cardiac compromise?
lack of O2 in the heart = makes the heart adapt and work harder to compromise for hypoxia
How do we treat for cardiac compromise? Why?
O2 | NEED to decrease O2 demand of the heart = decrease the workload
What are the 3 types of definitive care for cardiac compromise situations?
Cardiac Cath Lab | Clot-busting medications | Angioplasty/CABG
What are the 6 types of chest pain complaints in terms of location and type?
substernal/midsternal | one that radiates to neck, jaw, and L arm | heartburn/indigestion | apressure, squeezing and tightness
How do you differentiate GI-origin vs cardiac-origin heartburn/indigestion?
GI-originated indigestion is relieved with antacids | cardiac-origin indigestion is progressively worsened and not relived by antacids
How does hypoxia present itself in the patient?
will have pain
What are the 6 patient rights?
right patient | right drug | right dosage | right route | right time | documentation
How does nitroglycerine work?
vasodilates
What is the indication for nitroglycerine?
cardiac-related/origin chest pain
What are the 3 contraindications for nitroglycerine?
hypotension (low BP) | recently taken enhanced drugs | MOI related CP
What is the route for nitroglycerine?
sublingual
What must you always do before and after administering nitroglycerine?
check BP
What are the 3 side effects for nitroglycerine?
drops BP = light headed | dizziness | weak
What position must you place the patient who recently had nitoglycerine?
supine
Why do you want to vasodilate the blood vessels for someone who has an MI or CAD?
to supply more blood to the heart = decreasing workload
