Respiratory acidosis occurs when the arterial partial pressure of carbon dioxide (Pa CO2) is elevated above the normal range (>44 mm Hg) leading to a blood pH lower than 7.35.By definition, the diagnosis of respiratory acidosis requires measurement of Pa CO2 and pH. When the diagnosis is made, the underlying cause should be thoroughly investigated.
Lactic acidosis: Acidosis (too much acid in the body) due to the buildup of lactic acid in the body. Lactic acidosis occurs when cells make lactic acid (from glucose) faster than it can be metabolized.The key signs of lactic acidosis include unusually deep and rapid breathing, vomiting, and abdominal pain.actic acidosis: Acidosis (too much acid in the body) due to the buildup of lactic acid in the body.
