ICU

Question 1

Ideal Body Weight (IBW):

Answer 1

Female: 100 lb for 1st 5ft + 5lbs ea additional inch

b. Male: 106 lb for 1st 5 ft + 6lbs ea additiona

Question 2

Static Compliance: (VT/Static pressure – PEEP)

Answer 2

Normal = 60-100

b. <60 = lungs becoming less compliant
c. >25 is acceptable
d. <25 is unacceptable

Question 3

Desired FiO2

Answer 3

Desired FiO2 = Desired PaO2 + Known FiO2/Known PaO2

DP+KF/KP

Question 4

Desired Ve

Answer 4

Desired Ve= Known Ve*Known PaCO2/ Desired PaCO2

(KV*KC)/DC

Question 5

RAW:

Answer 5

RAW: PIP–Plateau/ Flow, or PIP–plateau

Question 6

French size sx catheter =

Answer 6

French size sx catheter = ETT size * 3/2

Question 7

PAO2:

Answer 7

PAO2: (713 *Fio2 – PaCO2)/0.8or 0.1 if 100% O2

Question 8

AA gradient

Answer 8

A-a gradient: PAO2 – PaO2

a. Normal on RA = 10-40 or on 100% = 25 – 70
b. Increased 66-300 = acute lung injury
c. >300 = severe shunting, ARDS (unacceptable)

Question 9

Shunt % =

Answer 9

Shunt % = A-a gradient/20; normal=20% – if >20 an increase in PEEP is indicated

Question 10

a-Aratio: PaO2-PAO2

a. Normal =
b. 60% =
c. 15% =

Answer 10

a-Aratio: PaO2-PAO2

a. Normal = 80% (74% elderly)
b. 60% = V/Q imbalance
c. 15% = shunting

Question 11

P/F Ratio: PaO2/FiO2

a. Normal =
b. Acute lung injury =

Answer 11

P/F Ratio: PaO2/FiO2

a. Normal = 300 – 500
b. Acute lung injury = 200 – 300 c. <200 = ARDS

Question 12

Expected PaO2 = ??

a. Used to determine if pt ??
b. Actual PaO2/ Expected PaO2 = %

Answer 12

Expected PaO2 = FiO2 x5
a. Used to determine if pt oxygenating better
b. Actual PaO2/ Expected PaO2 = % of patient
expected PaO2

Question 13

PS should be set to= ??or > ??

Answer 13

PS should be set to= RAW or > if therapy indicated.

Question 14

. e-cylinder time remaining=

Answer 14

e-cylinder time remaining=0.30(PSI) / LPM

Question 15

16. Oral intubation =
17. Nasal intubation =
18. PEEP therapy =

Answer 15

16. Oral intubation = 21-25cm @ lip.
17. Nasal intubation = 26-29cm
18. PEEP therapy = >6-8 CWP

Question 16

18. Humidity should be set at ??
19. Suction:Adult=???,Child=???Infant=??L
20. Pt.WOB=.??normal, measures effectiveness of
    rise time and sensitivity.

Answer 16

18. Humidity should be set at 37 degrees Celcius.
19. Suction:Adult=100-120,Child=80-100,Infant=60-80
20. Pt.WOB=<0.8=normal, measures effectiveness of
    rise time and sensitivity. Measured in spont. mode.
