Nursing & Medical Calculators
Free nursing and medical calculators for common clinical assessments, medication calculations, vital signs, and laboratory interpretation.
Creatinine Clearance Calculator
Calculate creatinine clearance using the Cockcroft-Gault equation. Supports actual, ideal, and adjusted body weight with automatic BMI-based weight selection and CKD staging.
ABG Interpreter
Enter arterial blood gas values to quickly identify acid-base imbalances. Get interpretation of the primary disorder, compensation status, and oxygenation assessment.
Anion Gap Calculator
Calculate the serum anion gap with albumin correction. Enter sodium, chloride, bicarbonate, and albumin to identify the type of metabolic acidosis and calculate the delta-delta ratio.
APGAR Score Calculator
Assess a newborn's condition using the APGAR scoring system. Evaluate appearance, pulse, grimace, activity, and respiration to determine if the baby needs immediate medical intervention.
Body Surface Area Calculator
Calculate body surface area (BSA) using both the Mosteller and Du Bois formulas. Supports metric and imperial units for height and weight inputs.
Corrected Calcium Calculator
Calculate the corrected calcium level adjusted for albumin. Enter total serum calcium and albumin to determine the true calcium status when albumin is abnormal.
Weight-Based Dosage Calculator
Calculate the correct medication dosage based on patient weight. Enter the ordered dose per kilogram, patient weight, and drug concentration to determine the total dose and volume to administer.
Glasgow Coma Scale Calculator
Assess a patient's level of consciousness using the Glasgow Coma Scale. Select the best eye, verbal, and motor responses to calculate the GCS score and severity classification.
IV Drip Rate Calculator
Calculate the correct IV drip rate in drops per minute (gtts/min) and flow rate in mL per hour. Enter the volume to be infused, infusion time, and your tubing's drop factor.
Mean Arterial Pressure Calculator
Calculate MAP from systolic and diastolic blood pressure readings. Get instant clinical interpretation of the result to assess perfusion status.
Morse Fall Scale Calculator
Assess patient fall risk using the Morse Fall Scale. Score six evidence-based risk factors to determine the appropriate level of fall prevention interventions.
Nurse Staffing Ratio Calculator
Calculate the number of nurses needed for your unit based on patient census, acuity level, and shift length. Determine nurse-to-patient ratios and hours per patient day (HPPD).
Oxygen Tank Duration Calculator
Calculate how long an oxygen tank will last based on cylinder size, current pressure, and flow rate. Plan transports and oxygen supply changes with accurate time estimates.
Parkland Burn Formula Calculator
Calculate fluid resuscitation requirements for burn patients using the Parkland formula. Enter body weight and burn percentage (TBSA) to determine crystalloid volume and infusion rates for the first 24 hours.
QTc Interval Calculator
Calculate the corrected QT interval using Bazett, Fridericia, and Framingham formulas. Enter the measured QT interval and heart rate from an ECG to assess QT prolongation risk.
