Base excess in the other. A secondary (compensatory) process can be readily identified because it "opposes" the observed deviation in blood pH. For example, inadequate ventilation, a respiratory problem, causes a buildup of CO, hence respiratory acidosis; the kidneys then attempt to compensate for the low pH by raising blood bicarbonate. The kidneys only partially compensate, so the patient may still have a low blood pH, i.e. acidosis. In summary, the kidneys partially compensate for respiratory acidosis by raising blood bicarbonate. A high base excess, thus metabolic alkalosis, usually involves an excess of bicarbonate. It can be caused by A base deficit
White-nose syndrome acidosis-induced extracellular shift of potassium. Dying, infected cells could also leak their (intracellular) potassium into the blood. The damaged wing epidermis might stimulate increased frequencies of arousal from torpor, which removes excess CO₂ and normalizes blood pH, at the expense of hydration and fat reserves. With worsening wing damage, the effects are exacerbated by water and electrolyte loss across the wound (hypotonic dehydration), which stimulates more frequent arousals in a positive feedback loop that ultimately leads to death. The disease was first reported in January 2007 in New York caves, although it was retrospectively detected in a photograph taken in
