Q

If pH is normal, PCO2 is high, HCO3 is high, this is what?

A

Compensated respiratory acidosis OR
Compensated metabolic alkalosis

17
Q

If pH is normal, PCO2 is low, HCO3 is low, this is what?

A

Compensated respiratory alkalosis OR
Compensated metabolic acidosis

18
Q

If pH is low, PCO2 is high, HCO3 is high, this is what?

A

Decompensated respiratory acidosis
pH went down as PCO2 went up; compensation occurred by HCO3 increasing to bring pH to normal; PCO2 went up further to cause lower pH again

19
Q

BE greater than +2 indicates what?

A

Metabolic alkalosis

20
Q

BE less than -2 indicates what?

A

Metabolic acidosis

21
Q

PEFR in obstructive disease is reduced. True/False?

22
Q

PEFR in restrictive disease is reduced. True/False?

A

False
It is usually normal

23
Q

24
Q

FEV1 is reduced in restrictive disease. True/False?

25
FVC is reduced in obstructive disease. True/False?
False Can be normal in asthmatics
26
FVC is reduced in restrictive disease. True/False?
True
27
FEV1/FVC is reduced in obstructive disease. True/False?
True
28
FEV1/FVC is the same in restrictive disease. True/False?
True
29
Which substances are used for bronchial challenge testing?
Methacholine, histamine, mannitol
30
What is Respiratory Failure?
Hypoxia (PaO2 less than 8kPa) with/without hypercapnia, occuring when gas exchange is inadequate
31
What is ARDS?
Respiratory stress due to stiff lungs and impaired gas exchange
32
What are the main causes of ARDS?
Lung injury Severe sepsis Pneumonia
