WebHigh base excess was found in 17 babies, among which arterial was a better predictor as 11 babies out of 17 (64.7%) had lower base excess values in the venous sample. Therefore, arterial base excess was a predictor for perinatal asphyxia. Therefore, umbilical cord blood pH, base excess along with lactate are best predictors of the outcome. Web13 de out. de 2024 · So a Base Excess of 6 means you’d need to add lots of acid to get back to normal, as the blood is alkalotic. A Base Excess of – 6 (that’s MINUS 6) means you’d need to take acid away, or add alkali, to get it back to normal, because the blood is acidic. To make it more tricky, a negative Base Excess is sometimes called a Base Deficit. Web30 de jan. de 2024 · What does a high base excess mean? A high base excess (> +2mmol/L) indicates that there is a higher than normal amount of HCO3– in the blood, which may be due to a primary metabolic alkalosis or a compensated respiratory acidosis.
