Negative base excess meaning
Before getting stuck into the details of the analysis, it’s important to look at the patient’s current clinical status, as this provides essential context to the ABG result. Below are a few examples to demonstrate how important context is when interpreting an ABG: 1. A ‘normal’ PaO2 in a patient on high flow oxygen: this … See more Your first question when looking at the ABG should be “Is this patient hypoxic?” as hypoxia is the most immediate threat to life. PaO2 should … See more At this point, prior to assessing the CO2, you already know the pH and the PaO2. So for example, you may know your patient’s pH is abnormal but you don’t yet know the underlying … See more Seemingly small abnormalities in pH have very significant and wide-spanning effects on the physiology of the human body. Therefore, paying close attention to pH abnormalities is essential. So we need to ask ourselves, is the … See more WebBase excess control. Siggaard-Andersen (1963) defined the base excess as the titrable base on titration to normal pH (7.4) at normal (40 mm Hg) and normal temperature (38 °C). The base excess can be either positive or negative, i.e. it indicates the surplus or the shortage of non-volatile buffer.

It refers to the amount of base needed to titrate a serum pH back to normal (healthy human-arterial blood pH varies between 7.35 and 7.45) when the contribution of respiratory factors is taken out of the equation. Base deficit is usually reported as a negative base excess.
