1. **What does ABG stand for?**
Arterial Blood Gas
2. **What are ABG common sites?**
radial, brachial, femoral
3. **What is the most common site for ABG?**
Radial
4. **Which ABG site would you use during a code?**
Femoral because strongest there during code
5. **Why is an ABG a critical test for diagnosis?**
Will determine the underlying cause of the acid base disturbance and how to treat it.

Gas exchange and metabolic processes
7. **What are the ABG Measured components?**
pH, PaCO2, PaO2
8. **What are the ABG calculated components?**
HCO3- , SaO2
1
,9. **What is the normal pH?**
7.35-7.45
10. **What is the normal PaCO2?**
35-45 torr
11. **What is the normal PaO2?**
80-100 torr
12. **What is the normal HCO3-?**
22-26 mE/L
13. **What is the normal SaO2?**
95% and above
14. **What is the pH electrode called?**
Sans
15. **What is the PaCO2 electrode called?**
Severinghaus
16. **What is the PaO2 electrode called?**
Clark
17. **What does the Clark electrode read in?**
30 seconds
18. **What is the standard ABG order?**
2
, pH / PaCO2 / PaO2 / HCO3- / SaO2
19. **What is the 1st part of the ABG order?**
pH
20. **What is the 2nd part of the ABG order?**
PaCO2
21. **What is the 3rd part of the ABG order?**
PaO2
22. **What is the 4th part of the ABG order?**
HCO3-
23. **What is the 5th part of the ABG order?**
SaO2
24. **What does pH measure?**
Presence of hydrogen ions (H+)
25. **Why do body fluids need to be kept within a narrow pH window?**
Proper body function
26. **Why does the body begin to function improperly when fluids aren't kept within
normal pH?**
Proteins denature/uncoil into random shape and may render the enzyme inactive.
27. **What does 7.35-7.45 specifically measure?**
3
, H+ (Hydrogen ion)
28. **What is the pH range compatible with life?**
6.8-7.8
29. **What is the middle of the normal pH range?**
7.4
30. **A pH of 7.40 is neither what?**
Acidic or Alkalotic
31. **What are some causes of Acidosis pH?**
Poor vascular tone, Myocardial pump failure, Arrythmia/Cardiac Dysrhythmia, Right
Shift O2 dissociation curve
32. **What are some causes of Alkalosis pH?**
Left shift O2 dissociation curve, Impaired cellular respiration, seizures, tingling of
extremities, irritability
33. **What is Arrhythmia/Cardiac dysrhythmia?**
Problem with rate of rhythm of the heart
34. **What is Acidosis?**
Less than 7.35
35. **What is Alkalosis?**
Greater than 7.45
36. **What is the Acidosis side of Normal pH?**
