Base excess or base deficit is an indication of the amount of anionic compound and hydrogen ion in the patient's blood compared to the "normal" level for that patient.
The results of ROC curve analysis for predictions of poor outcome (HIE/PND) on the basis of 1- and 5-min Apgar score, cord arterial blood isoprostane concentration, cord arterial pH, and cord arterial base excess are shown in Table 1.
The EG6+ cartridge will offer tests for blood gases along with sodium, potassium, hematocrit, as well as calculated values for bicarbonate, base excess, oxygen saturation, total carbon dioxide, and hemoglobin.
For each sample, the pH, carbon dioxide in the plasma bicarbonate, base excess, partial pressure of carbon dioxide, total carbon dioxide, partial pressure of oxygen and oxygen saturation were determined.
The analyzers had good agreement for total carbon dioxide, bicarbonate, pH, and Hgb, fair agreement for potassium (K), ionized calcium (iCa), venous partial pressure of carbon dioxide, and base excess, and poor agreement for sodium (Na), venous partial pressure of oxygen (P02), and oxygen saturation ([So.
Base excess or buffer base (strong ion difference) as measure of a non-respiratory acid-base disturbance.
In 16 patients there was a base excess of <-4 on presentation.
