AA Ratio Calculator

How to Use the AA Ratio Calculator

The AA Ratio Calculator is used to calculate the Acid-Base Ratio in medical contexts, which helps in diagnosing acid-base disorders. Follow these steps to use the calculator:

1. Enter the serum sodium level in mEq/L.
2. Enter the serum potassium level in mEq/L.
3. Enter the serum chloride level in mEq/L.
4. Enter the serum bicarbonate level in mEq/L.
5. Click the "Calculate" button to compute the AA Ratio.
6. The result will be displayed in the result field.

Understanding the Calculation

The AA Ratio is calculated using the formula:

AA Ratio = (Sodium + Potassium) / (Chloride + Bicarbonate)

This ratio helps in assessing the balance between acids and bases in the body. A higher ratio indicates an acidosis condition, while a lower ratio indicates an alkalosis condition.

Principle of Operation

The Acid-Base Ratio is a useful indicator in the diagnosis of metabolic acidosis and alkalosis. By comparing the sum of cations (sodium and potassium) to the sum of anions (chloride and bicarbonate), clinicians can gain insights into the underlying acid-base disturbance.
