Medical Calculator FAQs

Are these medical calculators clinically validated?

Yes, our calculators implement standard clinical formulas and guidelines from trusted medical sources. However, they are provided for informational use and should be confirmed against official sources for critical clinical decisions.

Do the calculators work offline?

Which ICU scoring calculators are included?

We offer critical care severity scores including SOFA, APACHE-II, qSOFA, Glasgow Coma Scale, and other ICU-specific assessment tools for rapid bedside evaluation of critically ill patients.

Is there a vancomycin dosing calculator?

Yes, our pharmacists' collection includes AUC-based and trough-guided vancomycin dosing calculators with weight-adjusted calculations, renal function adjustments, and monitoring recommendations.
