General ICU Information

Question 1

MAP (Mean Arterial Pressure) of what is acceptable in ICU?

Answer 1

60 - 80 mmHg

Too low (i.e. <60) could mean vital organs will not be getting enough oxygen perfusion, can become hypoxic and ischemic

Question 2

What are the acceptable values for CVP (Central Venous Pressure)?

Answer 2

5 - 15 cmH2O

Question 3

Acceptable values for HR in ICU?

Answer 3

60 - 100

Question 4

What is ‘RASS’ and what does it range from?

Answer 4

Richmond Agitation Sedation Scale

+4 = Combative (overly combative, violent, immediate danger to staff)
TO
-5 = Unarousable (no response to voice or physical stimulation

Question 5

What is ‘0’ on the Richmond Agitation Sedation Scale (RASS)?

Answer 5

Question 6

CPP =

Answer 6

CPP = MAP - ICP

Question 7

ICP (Intercranial Pressure) normative?

Answer 7

7-15 mmHg

Question 8

ARDS can be suggested by a PAO2:FiO2 (PF) ratio of

Answer 8

< 200

Question 9

Normal CI? (Cardiac Index)

Answer 9

2.5 to 4L/min

Question 10

What does Cardiac Index relate to?

Answer 10

Cardiac output from left ventricle in one minute to body surface area [thus relating heart performance to the size of the individual]

Question 11

PCWP acceptable values in ICU? [Pulmonary Capillary Wedge Pressure]

Answer 11

2 - 12

Question 12

CO normal?

Answer 12

4 - 7L / min
