Abg interpretation

The aniongap is usually calculated without potassium en that value is used to calculate the delta ratio. The first step involves calculating the anion gap , where there are different categories of differentials for either a normal anion gap metabolic acidosis NAGMA or a high anion gap metabolic acidosis HAGMA. Respiratory alkalosis reduced pCO2.

Supraglottic airway e.

Abg interpretation normal values

Table 1 : Characteristics of acid-base disturbances. Your Analysis. The pH is on the alkalotic side of normal , so the primary problem must be some sort of alkalosis. Respiratory acidosis elevated pCO2. Home ABGs.

Abg interpretation quiz

It explains each component in turn followed by clinical examples to work through. If the numerator is larger i. A metabolic alkalosis is compensated for by increasing pCO 2. Usually, compensation does not return the pH to normal 7. Delta ratio In the context of a metabolic acidosis, a further calculation can be performed to assess whether the metabolic acidosis is due to single process or a mixed acid-base disorder.

Leave a Reply Cancel reply. If there is a primary metabolic disorder, there is an expected respiratory compensation that can be calculated, and vice versa for a primary respiratory disorder. This CO 2 is acidotic , but the pH is on the alkalotic side of normal. ABG Interpretation. Lung Disease Week Median nerve lesion — exam presentation.

Here is one such system:. Obsolete browsers make your computer unsafe! If the denominator is larger i. The pH is on the high alkalotic side of normal , so the primary problem must also be an alkalosis , and the compensation must be an acidosis. What is the relationship between the direction of change in the pH and the direction of change in the PaCO 2?

Metabolic alkalosis elevated HCO 3. Table 6 : Selected mixed and complex acid-base disturbances. Emergency physician, Sir Charles Gairdner Hospital. Physician in training. German translator and lover of medical history.
