Flashcards in Random Factoids#2 Deck (17):
1

Stroke like symptoms & seizure suggest:

Hemorrhagic stroke - no fibrinolytics

2

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

CPP 70, CO 25%

3

Basilar skull fracture: facial symptoms & cranial nerve involvement

Facial palsy, nystagmus, facial numbness
Cranial nerves: V, VI, VII

4

When calculating the CPP, you don't know the ICP... What should you use?

Upper range of ICP normal, 0-15

5

DAI Simple definition & radiological Results

Injury that causes severe shearing of the axons of nerve cells

-CT & MRI = unidentifiable damage

6

Harsh systolic murmur

Traumatic Aortic a Rupture

7

Electrical Alterans

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

8

Normal split S2

Split on inspiration but not expiration.

9

Aldosterone

Fluid retention

10

DTRs & DKA

Drop in DTR suggest worse acidosis. Deterioration.

11

Sepsis initial fluid resus. Rate

30 ml/kg

12

SIRS leads to MODS, which organs are hit first

Respiratory failure followed by hepatic then renal.

13

CVP target for long lasting HTN or LV Hypertrophy

12-15

14

Goal SVO2 for severe sepsis pts

65-70%

15

MODS

Progressive insufficiency of 2 or more organ systems

16

Hyperdynamic sepsis cardiac response

Compensation: increased CO, CI, contractility

17

Septic shock cardiac response

Decrease preload/afterload, CVP, PAD, PCWP, CI
