Flashcards in Acid-Base Disturbances Deck (12):
Give examples of causes of respiratory acidosis?
Obstruction of airway
Drugs (which would depress resp centre)
Injury/infection of brain stem
What ABGs are typical of respiratory acidosis?
Increased Bicarbonate (HCO3-)
What clinical sign would suggest respiratory acidosis?
Body needs to get rid of CO2 to compensate
What can be a cause of respiratory alkalosis?
Hysterical over breathing
Typical ABGs of a patient with respiratory alkalosis?
Decreased pCO2 <4.7
List some causes of metabolic acidosis?
Excess metabolic production pf H+ (e.g. in DKA, lactate acidosis)
Loss of bicarbonate (e.g. severe diarrhoea)
Chronic Renal disease/failure (failure to excrete H+)
What ABG's would be seen in metabolic acidosis?
What can be done to alter the metabolic acidosis>
Alkali can be administered
What causes of metabolic acidosis will increase the anion gap?
Diabetic or Lactic acidosis
In what causes of metabolic acidosis does the anion gap remain unchanged/normal?
Renal tubular acidosis
List the causes of metabolic alkalosis
Vomiting/Diarrhoea - leading to loss of acid
Depleted ECF (burns, haemorrhage, excess diuretic use etc)
