Flashcards in Random Factoids Deck (26):
1

Lactate level and sepsis

Q point >2.5 increases mortality by 10%

2

O2 content dissolved in plasma equation

[1.34 x hgb x (SaO2/100)] + 0.003 x PO2
-Tissues draw o2 from plasma 1st, the from Hgb
-can be used with Fick formula as well to trend SvO2 & amount delivered.

3

Polycythemia

Increased RBC production in response to COPD hypoxia
-process also increase 2-3DPG

4

Ground glass opacities chest X-ray

Infection, pulmonary edema, cellular inflammation

5

Increased Dead Space vs Intrapulmonary shunt

Increased death space: no perfusion w/ ventilation
Intrapulmonary shunt: no perfusion or ventilation

6

Pleural Tube Water Seal fluctuation: spintaneous vs mechanical

Spontaneous:
-inhalation: water level rises (negative pressure)
-expiration: water level falls (positive Pressure)

Mechanical
-inhalation: falls (positive)
-exhalation: rise (neutral)

7

Leukocytosis

Indicates infection

8

SVO2 representation

O2 reserve, left over after tissue extraction

9

MAP representation

Organ tissue perfusion

10

Histotoxic hypoxia specific poisons

CO, cyanide, alcohol

11

Most common cause of Anaphylaxis

NMBA

12

Useful amount of consciousness w/ Rapid decompression

Greater than 30k ft msl - always choose the shortest amount of time.

13

As altitude increase as q 1000 ft, temps:

Decrease 2 degrees C

14

Glycogen stores limit

Shivering & producing heat.

15

Fresh water drowning pt

Systemic washout of surfactant: atelectasis

16

Salt water drowning pt

Hyper osmolar shift of fluid and blood products into pulmonary spaces. Treat as you would ARDS: low Vt, high f, high peep

17

Fever & Diaphoresis & Na levels

Decrease water through skin = Hypernatremic

18

Parathyroid hormone

Regulates Ca and phosphorous.
Less parathyroid=less Ca
-Ca and phosphorous gap have inverse relationship

19

Most common cause of increased Hct

Dehydration... Will also not increases Na levels

20

S/s hyponatremia

Convulsions, apprehension, abdominal cramps, diarrhea

21

Oliguria & sticky mucous membranes indicate high or low NA?

High Na

22

Increased urine specific gravity occur in?

SIADH, & dehydration

23

Urine Creatine Clearance directly reflects:

GFR (glomerular filtration rate)

24

Corrected vs uncorrected anion gap

Corrected: factoring of K (most accurate)

25

Two common tests for hypocalcemia

Chvostek's & Trousseau's

26

Hypocalcemia S/S

Numbness/tingling perioral, muscle cramps/spasms, irritability / fatique.
