Nursing Calculators

Dosage calculators

  1. PO dosage calculator – solids i.e. tablets, caplets, capsules, lozenges
  2. PO dosage calculator – liquids calculates liquid medications such as acetaminophen elixir
  3. IV dosage calculator calculates IV medications such as furosemide and digoxin

Calculate IV rates

  1. IV rate (gtt/min) calculates IV rates without using an IV pump
  2. IV rate (mL/hr) calculates IV rates when given a time limit when IV must be infused
  3. mcg/min as mL/hr calculates IV medication rates such as norepinephrine and nitroglycerine
  4. mcg/kg/min as mL/hr calculates IV medication rates such as nitroprusside and dopamine

Calculate infusion time

  1. IV time (hrs) given an IV rate, calculates the duration of an IV

Calculate dosage given or infusing

There are times when the only way to figure out how much medication is being infused is by looking at the information on the IV bag and the rate of the infusion.

  1. mL/hr as dose/hr calculates the dose of medications infusing such as heparin
  2. mL/hr as mcg/min calculates the dose of medications infusing such as nitroglycerine and norepinephrine
  3. mL/hr as mcg/kg/min calculates the dose of medications infusing such as dobutamine and nitroprusside

Clinical Calculators

  1. pediatric dose calculator converts an adult dosage into a pediatric using BSA
  2. O2 remaining in e-cylinder calculates how much O2 is left according to rate infusing
  3. bsa calculator calculates the BSA according to height and weight
  4. drug absorption (Pka) determines how well a medication will be absorbed into the body
  5. O.R. fluid requirements calculates IV rate according to the type of surgery
  6. N.P.O. fluid replacement calculates fluid replacement for time NPO
  7. allowable blood loss calculates how much blood can be lost without needing a transfusion
  8. estimated blood volume estimates how much blood is in a person’s body
  9. Ideal Body Weight (IBW) compares an individuals weight against a statistical norm
  10. Adjusted Body Weight (ABW) calculates the ABW in obese persons for more accurate drug dosing
  11. ABG interpreter interprets a respiratory or metabolic cause for pH disorders.

Conversion Calculators

  1. °F,°C conversions converts Fahrenheit and Celsius temperatures
  2. pounds to kilograms converts pound and kilogram weights
  3. inches to centimeters converts inch and centimeter lengths
  4. foot, inch to centimeters converts foot, inch and centimeter lengths (i.e 5’3″ = 160 cm)
  5. non-metric to metric converts gr, tsp, tbs, oz, cup, min, dr to metric
  6. metric units converts between metric weights and volumes
  7. % solutions to mg/mL converts % solution into mg/mL concentration
  8. epinephrine solutions to mg/mL chart that converts a ratio into a mg/mL concentration

Drug  Calculators

  1. Propofol bolus/infusion calculates how many mL to push for intubation or rates for sedation and maintenance
  2. Muscle relaxants calculates how many mL to push for intubation
