Flashcards in Anion Gap Deck (10):
Define metabolic acidosis?
Low pH - decreased HCO3-
What causes Met acidosis
Add acid, stop exc H+, lose HCO3-
What can be used to narrow diagnosis of met acidosis?
Define anion gap?
difference between conc of routinely measured anions (cl, hco3) and cations (na)
What is the formula for anion gap?
what is the normal range of anion gap?
what does a raised anion gap mean?
addition of exogenous acid
what is the ddx w/ a raised anion gap?
lactic acidosis, ketoacidosis, ethylene glycol/methanol poisoning, salicylate od
What does a normal anion gap mean?
loss of hco3 or failure to sec h
