Medicine & Clinical Tools Calculators (11)
Clinical math needs to be fast and exact, which is why this collection starts with an egfr calculator for estimating kidney function from creatinine, age, and sex, alongside a dedicated creatinine clearance option for the same real workflow. From there, work out body surface area for accurate drug dosing, mean arterial pressure from a blood pressure reading, and a corrected QT interval for reading an ECG correctly.
There is also real coverage for risk scoring and pediatric care: a CHADS2 stroke risk score for atrial fibrillation, a Wells Score for DVT risk, an IV drip rate calculator for setting an infusion correctly, and a pediatric weight estimation tool for a fast, weight based dosing reference. Round it out with an oxygen saturation altitude estimator and a caloric needs calculator for specific medical conditions. Every tool here is meant as an educational reference, not a substitute for real clinical judgment.
Body Surface Area (BSA) Calculator
Calculate body surface area (BSA) using the Mosteller or DuBois formula, with an optional medication-dose calculation from a dose density.
Open calculator →Caloric Needs for Medical Conditions Calculator
Calculate adjusted caloric needs for patients with conditions that increase metabolic demand.
Open calculator →CHADS2 Stroke Risk Score Calculator
Calculate CHADS2 or CHA2DS2-VASc stroke risk score for atrial fibrillation, with annual stroke risk percentage from real validation studies and sex-adjusted anticoagulation guidance.
Open calculator →Corrected QT Interval (QTc) Calculator
Calculate the heart-rate-corrected QT interval using Bazett formula.
Open calculator →Drug Dosage Calculator (mg/kg)
Calculate a total medication dose based on patient weight and a prescribed dosage rate. For educational reference only, not a substitute for clinical judgment.
Open calculator →eGFR / Creatinine Clearance Calculator
Estimate kidney function using either the 2021 CKD-EPI eGFR equation or the Cockcroft-Gault creatinine clearance formula, with automatic CKD staging and body-weight adjustment.
Open calculator →IV Drip Rate Calculator
Calculate the IV drip rate in drops per minute based on volume, infusion time, and drop factor.
Open calculator →Mean Arterial Pressure (MAP) Calculator
Calculate mean arterial pressure (MAP) and pulse pressure from systolic and diastolic blood pressure readings, with a general interpretation based on standard reference ranges.
Open calculator →Oxygen Saturation Altitude Estimator
Estimate the expected drop in blood oxygen saturation at higher altitude.
Open calculator →Pediatric Weight Estimation Calculator
Estimate a child approximate weight from age, using a standard pediatric estimation formula.
Open calculator →Wells Score Calculator (DVT Risk)
Calculate a simplified Wells score, used to estimate the clinical probability of deep vein thrombosis.
