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 is dynamic compliance?
Dynamic compliance is static compliance plus airway resistance.
bronchospasm would affect dynamic compliance because it increases
airway resistance.Differentiate between the factors that affect airway
resistance and factors that affect expansion of the alveoli, lung, or
chest wall. Dynamic compliance is affected by airway resistance
factors.
Commotio cordis is a phenomenon in which:
ventricular fibrillation is induced following blunt trauma to the chest
during the heart's repolarization period.
Ashman phenomenon
Aberrant conduction of a supraventricular beat commonly seen in
patients with atrial fibrillation; wide SV beat after a QRS complex that
is preceded by a long pause.
Which of the following may be useful in systolic dysfunction but may be
detrimental in diastolic dysfunction?
A.
, β-blockers
B.
Angiotensin-converting enzyme inhibitors
C.
Aldosterone antagonists
D.
Vasodilators
Vasodilators are used for preload and afterload reduction in systolic
dysfunction but may detrimentally decrease diastolic filling in
diastolic dysfunction.
A holistic murmur at the left sternal border means the
the tricuspid valve is most likely affected.
a patient with valve vegetation from IV venous drug use is most likely to
have vegetation on what valve? resulting in risk of which condition...
the Tricuspid valve... Pulmonary emboli
the valve most likely affected in this patient is the tricuspid valve and
that the blood (and any emboli) will go to the pulmonary artery and
the lungs. E
