what are the common signs of shock?
hypotension, tachycardia, tachypnea and altered LOC
What are the common signs that are unique to distributive shock?
warm, pink skin and bounding pulses
what are the signs unique to anaphylactic shock?
wheezing, stridor, edema and hives
what is the cause of decreased BP and decreased organ perfusion in distributive shock?
massive vasodilation
what is the cause of decreased BP and decreased organ perfusion in cariogenic shock?
impaired contractility
what is a sign unique to cariogenic shock?
distended jugular veins
what is a sign unique to hypovolemic shock?
flat jugular veins
what is the cause of decreased BP and decreased organ perfusion in hypovolemic shock?
decreased circulating blood volume
what are signs unique to septic shock?
fever and increased white blood cells
neurogenic shock results from what type of injury?
spinal cord injury, not head or brain injury
what causes vasodilation in neurogenic shock?
loss of sympathetic tone in arterioles
which type of shock does tachycardia NOT occur in?
neurogenic shock. Bradycardia occurs instead
where must the spinal cord injury occur for neurogenic shock to happen?
at or above T6
Variant (Prinzmetal’s) Angina is a result of?
vasospasm
stable angina is a result of?
stable plaques
unstable angina is a result of?
unstable plaques
Pain with variant angina is often?
cyclical and occurs at night
What are the risk factors of stable angina?
smoking, hypertension, dyslipidemia and diabetes
pain with stable angina is?
triggered by something, predictable and is relieved by rest
Unstable angina falls in the category of?
acute coronary syndrome
what is the difference between MI and unstable angina?
pain is prolonged (20-30 mins) and ischemia causes irreversible hypoxia.
What are two complications of MI?
Cariogenic shock and heart failure
what two things are classified in acute coronary syndrome?
unstable angina and MI
in unstable angina, ischemia is?
reversible
