: a nonmetallic chiefly tetravalent element found native (as in diamond and graphite) or as a constituent of coal, petroleum, and asphalt, of limestone and other carbonates, and of organic compounds or obtained artificially in varying degrees of purity especially as carbon black, lampblack, activated carbon, charcoal, and coke — see Chemical Elements Table These example sentences are selected automatically from various online news sources to reflect current usage of the word 'carbon.'

An actual or relative increase in the acidity of blood due to an accumulation of acids (as in diabetic acidosis or renal disease) or an excessive loss of bicarbonate (as in renal disease).

Prescribed intravenous fluids, medications, e.g., sodium bicarbonate or insulin, and other therapies, e.g., oxygen or mechanical ventilation, are administered.

The patient is positioned to promote chest expansion and repositioned frequently.

The acidosis is induced by urinary wasting of bicarbonate and inability to excrete phosphoric and sulfuric acids.

Renal acidosis due to one of the renal tubular acidoses responds to treatment either with sodium bicarbonate or with citrated salts (e.g., potassium citrate).

The anion gap metabolic acidoses include diabetic, alcoholic, and lactic acidoses; the acidosis of renal failure; and acidoses that result from the consumption of excess acids e.g., salicylates, methanol, or ethanol.Alkalis such as sodium bicarbonate or Shohl's solution are effective treatments.Type II (proximal RTA) is caused by impaired reabsorption of bicarbonate by the proximal tubules.Compensatory mechanisms maintain the normal ratio of bicarbonate to carbonic acid (approx.20:1) in blood plasma even though the bicarbonate level is decreased or the carbon dioxide level is elevated.The hydrogen ion concentration of the fluid is increased, lowering the p H.
