Arterial blood gases Flashcards
1
Q
What is the normal PH level range and description
A
7.35-7.45
- measures H+ in blood
2
Q
What is the normal PaCo2 level range and description
A
35-45
- respiratory
- measures CO2 in blood
- affected by CO2 removal in lungs
3
Q
Normal HCO3 range and description
A
- Metabolic
- measures bicarbonate
- affected by renal production of bicarbonate
4
Q
Respiratory acidosis compensation
A
- kidneys eleminate H+ = increase ph
- hypoventilation
5
Q
Respiratory alkalosis compensation
A
- kidneys eliminate HCO3 = decrease PH
- hyperventilation
6
Q
Metabolic acidosis compensation
A
excretes C02
keeps HCo3
7
Q
Metabolic alkalosis compensation
A
increase CO2
excrete HCO3
8
Q
Respiratory acidosis causes
A
- COPD
- pneumonia
- hypoventilation
- asthma.
9
Q
Metabolic acidosis causes
A
renal failure
diarrhoea
diabetes
vomiting
shock.
10
Q
metabolic alkalosis causes
A
- vomiting
- intake of antacids
- gastric suctioning
