cardiac

QuestionAnswer
MAP definition average pressure during cardiac cycle
Why is MAP important? to make sure organs are getting enough blood
Normal MAP 93%
Pulse pressure definition deference between diastolic and systolic pressure
Why is pulse pressure important? arterial stiffness and compliance
Normal pulse pressure 40
abnormal pulse pressure below 40 (heart failure) OR above 50 (heart disease/stroke)
Heart rate reserve definition 220 minus age minus resting HR

Stroke volume volume of blood ejected per L ventricle contraction
Ideal cardiac output 4-6 liters

V02 directly correlates to what? height and weight
Frank sterling principle increased stretch= increased contractability
After load force required to open aortic valve

HDL Good cholesterol
LDL Bad cholesterol
Contraindication of hemoglobin <8g/100ml
Precaution of hematocrit <20%
PET scan is gold standard for what? blood flow
Low ABI indicates what? Low arterial blood flow
STEMI Major coronary arteries completely blocked "Big Bang"
