1
Q

Stroke like symptoms & seizure suggest:

A

Hemorrhagic stroke - no fibrinolytics

2
Q

Normal CPP minimum to perfuse brain? What % CO goes to brain?

A

CPP 70, CO 25%

3
Q

Basilar skull fracture: facial symptoms & cranial nerve involvement

A

Facial palsy, nystagmus, facial numbness

Cranial nerves: V, VI, VII

4
Q

When calculating the CPP, you don’t know the ICP… What should you use?

A

Upper range of ICP normal, 0-15

5
Q

DAI Simple definition & radiological Results

A

Injury that causes severe shearing of the axons of nerve cells

-CT & MRI = unidentifiable damage

6
Q

Harsh systolic murmur

A

Traumatic Aortic a Rupture

7
Q

Electrical Alterans

A
  • caused by pericardiac tamponade of effusion
  • due to fluids in sac
  • alteration of QRS amplitude, or axis between beats, possible wandering baseline.
8
Q

Normal split S2

A

Split on inspiration but not expiration.

9
Q

Aldosterone

A

Fluid retention

10
Q

A

12-15

14
Q

Goal SVO2 for severe sepsis pts

A

65-70%

15
Q

MODS

A

Progressive insufficiency of 2 or more organ systems

16
Q

Hyperdynamic sepsis cardiac response

A

Compensation: increased CO, CI, contractility

17
