• Oral and pediatric dosage
• Insulin sliding scale
• Vancomycin and aminoglycoside dosing, phenytoin correction
• Morphine milligram equivalents (MME), benzodiazepine and steroid conversions
IV and infusion
• IV drip rate (gtt/min) and IV flow rate (mL/hr)
• Convert mL/hr to gtt/min, and gtt/min back to mL/hr
• Drop-factor presets for 10, 15, 20 and 60 gtt/mL, with the rate shown at each drop factor
• mcg/kg/min to mL/hr and titration
• Volume over time, TPN rate, blood transfusion rate
• Glucose infusion rate and enteral feed rate
Fluids, labs and body measurements
• Maintenance fluids (adult and pediatric), fluid deficit, Parkland formula for burns
• Intake and output balance
• BMI, pediatric BMI percentile, BSA (Mosteller), ideal and adjusted body weight
• Mean arterial pressure, anion gap, corrected calcium and sodium, serum osmolality
• Creatinine clearance, eGFR, corrected QT (QTc), A-a gradient

Clinical scores
Glasgow Coma Scale, Braden, Norton, Waterlow, NEWS, MEWS, APGAR, Morse Fall Scale, RASS, CIWA-Ar, Aldrete, NIHSS, Wells (DVT), CURB-65 and FLACC pain scale. Each score keeps a running total in view and shows its interpretation bands and source.

Check the math
Every calculator has a Formula and source panel that describes exactly what is computed and names the reference formula where one applies, such as Cockcroft-Gault, CKD-EPI 2021, Mosteller, Holliday-Segar, Parkland and Bazett.
Built for the shift
• Unit converters for weight, length, volume, dose units and temperature
• Quick reference cards
• Material 3 design in light and dark, in portrait or landscape
• Calculations run on your device and work offline. No patient data is collected or stored.
