ABG Calculator

The ABG Calculator aids medical professionals and students to interpret the results of arterial and venous blood gas samples. The clinician has the ability to alter the patient data such as cardiac output and haemoglobin to determine the present or predicted oxygen delivery. The calculator allows clinicians to optimize oxygen delivery and determine the effects of altered cardiac, haemoglobin or FiO2 that may alter oxygen delivery and utilization.

This calculator also provides easy access to the equations, normal and critical ranges of values, and clinical notes on how to interpret the calculated data.

Please refer to the "References" for complete medical information. This calculator is not a substitute for medical knowledge and is not to be used as the basis for medical treatments.
