What is the base excess? Base excess (BE) measures all bases, not just bicarbonate. However, because bicarbonate is the greater part of the base buffer, for most practical interpretations, BE provides essentially the same information as bicarbonate. The major advantage of BE is that its normal range is really easy to remember.
Arterial blood gases (ABGs) is a collective term applied to three separate measurements—pH, Pco2, and Po2—generally made together to evaluate acid–base status, ventilation, and arterial oxygenation. Oxygen (O2) and carbon dioxide (CO2) are the most important respiratory gases, and their partial pressures in arterial blood reflect the overall adequacy of gas exchange. Pao2 is affected by ...
Mar 1, 2019 · A low bicarbonate and negative base excess indicates a metabolic acidosis (and a low pCO 2 indicates respiratory compensation, and may clinically appear as tachypnoea/Kussmaul breathing). Alkalosis: a low pCO 2 indicates respiratory alkalosis, which may be due to hyperventilation (e.g. in a struggling child), but can be due to elevated ammonia ...
The base excess. The metabolic component of the acid–base balance is reflected in the base excess. This is a calculated value derived from blood pH and PaCO 2. It is defined as the amount of acid required to restore a litre of blood to its normal pH at a PaCO 2 of 40 mmHg. The base excess increases in metabolic alkalosis and decreases (or ...
Intrapartum asphyxia is responsible for only a small proportion of cerebral palsy cases, although obstetricians are often held accountable. Umbilical cord pH and blood gas values provide valuable information regarding the status of the infant at birth; base excess determination quantifies the magnitude of metabolic acidosis, the putative risk factor for central neurologic injury. Human and ...

Base excess refers to the quantity of bicarbonate in the plasma that can counteract an excess of nonvolatile acids. It is typically measured in millimoles per liter (mmol/l), with a normal range of -2 to +2 mmol/l. A negative base excess indicates metabolic acidosis, where the body is producing too much acid or not eliminating enough acid.
