Acid-base disturbances may indicate an underlying disease or organ damage.. Accurate interpretation of acid-base disturbances requires the following:. Acid-base balance.  . * Acids are electrolytes that release hydrogen ions (H+) when they are dissolved in water.. * Bases are electrolytes are release hydroxide ions (OH-) when they are dissolved in water..
