Blood Values

Question 1

Hb

Answer 1

General: 120-180
F: 120-140
M: 140-180

Question 2

Hypoxemia vs. Hypoxic

Answer 2

Hypoxemia occurs when the PaO2 in the blood falls below the normal value - less than 80mmHg (as people age their normal PaO2 will drop also, so for an older adult hypoxemia may only occur when PaO2 is below 60mmHg). This would also correlate with a lower SpO2 below 90%.

Hypoxia refers to a lack of oxygen in the tissues or in a specific tissue/organ, with PaO2 dropping below 80mmHg or SpO2 below 90%.

Question 3

WBC

Answer 3

5-10

Question 4

Plt

Answer 4

150-400

Question 5

PaO2 - how much oxygen is in the artery (98%)

Answer 5

mild: <80
moderate: 60-80
severe: <60

below 80mmHg = below 90%

Question 6

SpO2 - saturation of oxygen of hemoglobin

Answer 6

normal = 90/92%

Question 7

PaCO2

Answer 7

35-45

Question 8

pH

Answer 8

7.35-7.45

Question 9

HCO3 bicarbonate

Answer 9

22-26

Question 10

Base Excess

Answer 10

-2 - +2

Question 11

PEEP

Answer 11

5-14, never below 5

Question 12

Pressure Support PS

Answer 12

range 8-22

low: 8-12
mod: 13-16
high: 17-22

Question 13

Add PEEP and PS

Answer 13

stay under 40

- blow up the lung

Question 14

FiO2

Answer 14

low: ideal
high: requires mechanical support

• PaO2 is under 60, while more than 50% FiO2 = indication of mechanical ventilation

Question 15

Levophed

Answer 15

low: 0.01-0.04 ug/kg/min
high: 2.0

Question 16

Vasopressin

Answer 16

0.02-0.06
“pressin: suppressing the fluid”

• function: retains water

Question 17

cephazolin

Answer 17

anti-biotic

Question 18

solumedrol

Answer 18

corticosteroid
