How to Write an ABG
Instructions
-
-
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.
