Shock States
These are the four different shock states
What is distributive, hypovolemic, cariogenic, and obstructive?
This is the desired physiologic response when vasopressors are initiated
What is vasoconstriction or increased blood pressure?
This is the disease state when an inotrope may be preferred over a vasopressor
What is cardiogenic shock?
This is the amount of blood ejected with each beat of the heart
What is Stroke Volume
This receptor is the primary target of norephinephrine?
What is alpha 1 adrenergic receptor?
This is the primary deficit in distributive shock
What is Afterload?
This vasopressor is preferred in septic shock?
What is norepinephrine?
This is the primary receptor targeted by dobuatmine to produce its inotropic effect
This is the force that a ventricle must overcome while it contracts during ejection
What is Afterload or Systemic Vascular resistance?
This is the main location of the B1 adrenergic receptor
What is the heart?
This is an example of a cause of obstructive shock
What is pulmonary embolism, cardiac tamponade, or pericardial effusion?
This vasopressor is not titrated to effect, but rather dosed at a constant infusion rate?
What is vasopressin?
This is the mechanism of action of milrinone
What is PDE-3 inhibition?
This is the volume of blood being pumped by the heart per unit of time
What is cardiac output?
This is the primary role of the D4 receptor when stimulated by a dopamine agonist
What is increased contractility and increased cardiac output?
What happens to preload in the setting of hemorrhagic shock?
What is decreased?
This vasopressor has approximately 50% alpha 1 agonism and 50% beta 1 agonism
What is epinephrine?
This inotrope is really dose adjusted
What is milrinone?
This is a physiologic state of hypoperfusion
What is shock?
This is the receptor that is activated at maximum doses of dopamine
What is alpha 1 adrenergic receptor?
These are the three physiologic changes that occur in the setting of cardiogenic shock (preload, cardiac output, and afterload)
What is:
Preload: increased
Cardiac output: decreased
Afterload: increased
This is the mechanism of action of the drug used to reverse extravasation from a vasopressors (like norepinephrine)
What is alpha 1 antagonism?
These are three major side effects of dobutamine
Hypotension, tachyarrhythmias, and chest pain or headache?
This is the MAP of a patient with a SBP of 78 and a DBP of 45
What is 56?
What is V1 and V2 receptors?
