A

Distributive.

6

A

Distributive.

7

8
Q

3 components of qSOFA?

A
  • RR>=22
  • AMS
  • SBP=<100
9
Q

Difference between CMS definition vs Sepsis-3 definition of “Septic Shock”?

A
  • Sepsis-3: pressors and LA>2

10
Q

Location and function of alpha-1 receptors?

A

In vascular smooth muscles. Causes vasoconstriction.

11
Q

Location and function of alpha-2 receptors?

A

In CNS, platelets. Causes sedation, analgesia, platelet aggregation.

12
Q

Location and function of beta-1 receptors?

A

In heart. Mediates contractility & tachycardia.

13
Q

Location and function of beta-2 receptors?

A

Located in smooth muscles of bronchi, mediates bronchodilation. Also located in blood vessels, mediates dilation of coronary and skeletal vasculature.

14
Q

Dopamine functions at which receptors, based on dose?

A

Alpha, then beta, then DA.

15
Q

Location and function of angiotensin receptors?

A

Located in adrenal zona glomerulosa, vascular smooth muscle, kidney, brain, anterior pituitary. Causes vasoconstriction.

16
Q

Receptor and effect of phenylephrine?

A

Alpha-1 only. Causes vasoconstriction.

17
Q

Receptor and effect of norepinephrine?

A

3x alpha-1. 2x beta-1. Causes mainly vasoconstriction, and some increased cardiac output.

18
Q

Receptor and effect of epinephrine?

A

3x alpha-1, 3x beta-1, 2x-beta-2. Causes increased cardiac output, variable effect on SVR.

19
Q

Receptor and effect of low-dose dopamine?

A

Mild beta-1, and D1. Causes increased cardiac output and variable effect on SVR.

20
Q

Receptor and effect of med-dose dopamine?

A

1x alpha-1, 2x beta-1, 2x DA. Causes increased cardiac output and SVR.

21
Q

Receptor and effect of high-dose dopamine?

A

2x alpha-1, 2x beta-1, 2x DA. Causes increased cardiac output and SVR.

22
Q

Receptor and effect of dobutamine?

A

3x beta-1, 2x beta-2. Causes increased cardiac output and lower SVR.

23
Q

Hemodynamic effect of vasopressin?

A

Causes increased SVR.

24
Q

Contraindications to vasopressin infusion?

A

Cardiac, skin, or intestinal ischemia.
