Rule of 80's

The rule of 80's is a method of interpreting a person's acid-base status using an arterial blood gas.  It is a quick way to determine if a patient has metabolic acidosis, metabolic alkalosis, respiratory acidosis, or respiratory alkalosis.  It does not say anything about the cause of the acid-base disturbance.
