ABGs Flashcards
1
Q
What is the normal range for pH?
A
7.35 - 7.45
2
Q
What is the normal range for PaO2?
A
> 10.6kPa (75-100mmHg)
3
Q
What is the normal range for PaCO2?
A
4.7 - 6kPa (35-45 mmHg)
4
Q
What is the normal range for HCO3?
A
22-28mmol/L
5
Q
Define metabolic acidosis
A
Low pH and Low HCO3
Causes of metabolic acidosis will depend on the value of the anion gap (normal range 10-18mmol/L)
6
Q
Define metabolic alkalosis
A
High pH and High HCO3
7
Q
Define respiratory acidosis
A
Low pH and High CO2
8
Q
Define respiratory alkalosis
A
High pH and Low CO2
9
Q
What does a low pCO2 correspond with?
A
Hyperventilation - which should normally correspond with a high pO2.
If pCO2 is low and pO2 is normal or low, this may be an indication that the patient is beginning to go into respiratory distress. Seek help ASAP.
