ABG2 Flashcards
Diuretic (Cl wasting with increased renal bicarb resorption)
Metabolic alkalosis
Increased mineralocorticoid (drugs, hyperaldosteronism)
Metabolic alkalosis
Increased intake of alkali
Metabolic alkalosis
CNS depression from drugs or brain injury
Respiratory acidosis
Neuromuscular d/o (spinal cord injury, botulism, ALS, Gilliain barre)
Respiratory acidosis
Acute flair of obstructive lung disease
Respiratory acidosis
Hyperventilation
Respiratory alkalosis
Salicylates, SIRS, pulmonary disease (acute PE, flair of asthma), hypoxia
Respiratory alkalosis
PCO2 down by 1.25 mmHG for every 1 meq/L of HCO3
Metabolic acidosis
PCO2 up by 0.75 mmHG for every 1 meq/L of HCO3
Metabolic acidosis
If bicarb is down, ______ should be down
PCO2
HCO3 increased by 1 for every 10 increase in PCO2
Acute respiratory acidosis compensation
HCO3 increased by 4 for every 10 mmHG
Chronic respiratory acidosis compensation
HCO3 decreased by 2 for every 10 decreased in PCO2
Acute respiratory alkalosis compensation
HCO3 decreased by 4 for every 10 decrease in PCO2
Chronic respiratory alkalosis compensation
Narcotic OD
Respiratory acidosis
Ingestion of methanol
Anion gap metabolic acidosis
Anion gap exceeds change in Bicarb
Metabolic alkalosis
Vomiting
Metabolic alkalosis
If anion gap is elevated significantly, it should be proprionate to ___________ in Bicarb
Decrease
If decrease in Bicarb is less than elevation in anion gap indicates
Anion gap metabolic acidosis and metabolic alkalosis
If PCO2 and Bicarb change in same direction disorder is
Metabolic
If PCO2 and Bicarb change in opposite directions d/o is
Respiratory
