Chapter 27. Metabolic alkalosis, respiratory acidosis and respiratory alkalosis
Previous Chapter Next Chapter Self-Assessment for this chapter
Keypoints
- In a metabolic alkalosis plasma bicarbonate is raised.
- This usually arises from loss of body acid, inappropriate excess renal bicarbonate reabsorption or administration of alkali.
- Aldosterone excess causes excess renal bicarbonate reabsorption.
- A normal plasma chloride concentration is required for normal renal bicarbonate excretion.
- A rise in plasma carbon dioxide level causes a respiratory acidosis.
- A fall in plasma carbon dioxide level causes a respiratory alkalosis.
- Panic attacks cause a transient respiratory alkalosis and transient hypocalcemia.
