Alkalosis / Acidosis Flashcards
1
Q
Resp acidosis causes
A
CO2 retention:
Respiratory failure
Hypoventilation
COPD
2
Q
Resp acidosis compensation
A
RENAL
Kidneys increase H+ excretion - in ammonium form
HCO3- retention
3
Q
Resp alkalosis causes
A
CO2 depletion - hyperventilation:
Type 1 resp failure
Anxiety / panic
Hypoxia
4
Q
Resp alkalosis compensation
A
RENAL
Retain H+
Increased HCO3- loss
5
Q
Metabolic acidosis causes
A
Dilution of blood - more H20
Excess H+ load
Failure of H+ excretion
HCO3- loss eg. diarrhoea
6
Q
Metabolic acidosis compensation
A
RESP
Chemoreceptors stimulated - increased breathing - fall in CO2
7
Q
Metabolic alkalosis causes
A
Alkali ingestion
GI acid loss eg. vomiting
Renal acid loss eg. hypokalaemia
8
Q
Metabolic alkalosis compensation
A
RESP
Chemoreceptors inhibtied - reduces breathing - increases CO2
