How to Write an ABG
- 1). Write the calculated pH level to the nearest one-hundredth. For example, a normal blood pH would be 7.39.
- 2). Place a "/" behind the pH value. Continuing from the above example, the ABG now reads 7.39/.
- 3). Write the calculated partial pressure of carbon dioxide (PaCO2) expressed as a whole number. The ABG now reads "7.39/42."
- 4). Place a "/" behind the PaCO2. The ABG now reads "7.39/42/."
- 5). Write the calculated partial pressure of oxygen (PaO2). The ABG now reads "7.39/42/80."
- 6). Place a "/" behind the PaO2. The ABG now reads "7.39/42/80/."
- 7). Write the calculated bicarbonate level. The ABG now read "7.39/42/80/24," and is complete.
