The Antivenom Dosing Algorithm is a clinical calculator used in the management of patients who have been bitten by venomous creatures, such as snakes, spiders, and scorpions. This algorithm helps clinicians determine the appropriate dose of antivenom to administer based on the severity of the patient's symptoms and the type of creature involved. The clinical utility of this calculator is to provide a standardized approach to antivenom dosing, which can help reduce the risk of complications and improve patient outcomes. This calculator is not applicable to patients who have been bitten by non-venomous creatures or those who have allergic reactions to antivenom.
