Respiratory Alkalosis Flashcards

Q
Respiratory Alkalosis
A
Common Causes:
- Anxiety leading to Hyperventilation
- PE
- Salicylate poisoning
- CNS disorders: Stroke, SAH, Encephalitis
- Altitude
- Pregnancy
NB Anxiety should not lead to a decreased PO2! Whereas PE you would see hypoxia - how to differentiate
Salicylate OD tends to lead to a mixed respiratory alkalosis and metabolic acidosis.
Early stimulation of respiratory centre leads to respiratory alkalosis whilst later the direct acid effects of salicylates (combined with ARF) may lead to acidosis
