Data Source and Methodology
Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da MDCalc's Winters Formula.
The Formula Explained
Expected pCO2 = 1.5 * [HCO3-] + 8 ± 2
Glossary of Variables
- Bicarbonate (HCO3-): The concentration of bicarbonate in the blood, measured in mEq/L.
- Expected pCO2: The expected partial pressure of carbon dioxide in arterial blood, measured in mmHg.
Practical Example
For a bicarbonate level of 24 mEq/L, the expected pCO2 is calculated as: 1.5 * 24 + 8 = 44 mmHg (±2).
Frequently Asked Questions (FAQ)
What is Winter's Formula?
Winter's formula is used to calculate the expected pCO2 in metabolic acidosis.
How to use the Winter's Formula Calculator?
Input the bicarbonate value (HCO3-) to calculate the expected pCO2 using Winter's formula.
Why is this calculation important?
Understanding the expected pCO2 helps in assessing if the respiratory system is compensating properly for metabolic acidosis.
What does the ±2 mean in the formula?
The ±2 accounts for normal physiological variations in pCO2 levels.
Can this be used for patients with respiratory disorders?
This calculator is tailored for metabolic acidosis; other formulas may be more suitable for respiratory disorders.
