Arterial Blood Gas (ABG) Calculator

Formula

To calculate the Arterial Blood Gas (ABG):

\[ ABG = (HCO3 \times 1.5) + 8 \pm 2 \]

Where:

\(ABG\) is the Arterial Blood Gas value (mmol/L)
\(HCO3\) is the Bicarbonate Level (mmol/L)

What is an Arterial Blood Gas (ABG)?

An Arterial Blood Gas (ABG) is a blood test that measures the levels of oxygen and carbon dioxide in the blood, as well as the acidity (pH) of the blood. It is typically performed by drawing blood from an artery, usually in the wrist. The test provides information about how well the lungs are functioning and how well the body is able to transport and use oxygen. It can be used to diagnose and monitor conditions such as asthma, chronic obstructive pulmonary disease (COPD), or heart failure.

Example Calculation

Let's assume the following value:

Bicarbonate Level (\(HCO3\)) = 24 mmol/L

Using the formula:

\[ ABG = (24 \times 1.5) + 8 = 36 + 8 = 44 \pm 2 \]

The Arterial Blood Gas (ABG) value is 44 mmol/L, with a range of 42 to 46 mmol/L.
