NEWEST ACTUAL EXAM QUESTIONS AND
VERIFIED ANSWERS GRADED A+
What three things cause cerebral vasoconstriction?
Hypertension
Hypocarbia
Alkalosis
Which things cause cerebral vasodilation?
Hypotension
Hypercarbia
Acidosis
What MAP range is necessary for cerebral auto regulation to be
maintained?
50-150 mm Hg
,What happens to cerebral blood flow when the patient is hypoxic? (
pao2 less than 50)?
Cerebral vasodilation occurs.
How do you calculate MAP?
Systolic BP + (2 x DBP) / 3
Which leads look at the inferior surface of the heart? ie RV infarction
inferior MI?
II III & aVF
What are some physical exams you can perform to assess systemic
vascular resistance?
pulse pressure variation
What are Kinematics and why do we care?
Kinematics and the physics of energy transfer
,What isdynamiccompliance?
h
Dynamic compliance is static compliance plus airway resistance.
bronchospasm would affect dynamic compliance because it increases
airwayresistance.Differentiatebetweenthefactorsthataffectairway
resistance and factors that affect expansion of the alveoli, lung, or chest
wall. Dynamic compliance is affected by airway resistance factors.
