Name four potential causes of metabolic acidosis
- Either due to loss of HOC3 or the addition of H+
Lactic acidosis
Diabetic ketoacidosis
Drugs
Diarrhoea (loss of bicarbonate)
Name three potential causes of metabolic alkalosis
- Caused by loss of H+
Vomiting
Burns
Diuretics
Name a cause of respiratory acidosis
Caused by the retention of CO2
Causes: COPD
Name the potential causes of respiratory alkalosis
Caused by hyperventilation i.e. blow off excess CO2
Causes: Stroke, meningitis, anxiety, asthma, fever

b) basic
b) basic
Acts slower to compensate
