ABG Analyzer MDCalc

The ABG Analyzer MDCalc tool interprets arterial blood gas values by applying standard acid-base equations and oxygenation considerations. It focuses on domain logic, not UI, to deliver precise, repeatable interpretations for clinical use.
The core algorithm follows Henderson-Hasselbalch principles to relate pH, pCO2, and HCO3- values, then classifies the primary disorder and compensatory response. Additional metrics such as base excess and optional anion gap are computed when supporting data are provided.
The tool is designed for clinicians, residents, and laboratory staff who require a structured, auditable interpretation that can be documented in patient notes or integrated into electronic health records. It supports quick validation of results and aids in reporting by offering a clear, text-based diagnosis line alongside numerical outputs.
When pO2 or oxygenation inputs are supplied, the tool can present approximate oxygenation metrics and flag potential hypoxemia in the context of the ABG result. Its calculations adhere to widely accepted clinical guidelines, with explicit handling of missing or out-of-range inputs.
The value proposition is accuracy, consistency, and speed in decision support, suitable for bedside use, charting, and educational scenarios where standardization matters.
