Allowable Blood Loss Calculates how much blood can be lost without needing a transfusion. Fluid Replacement Calculates fluid replacement for time NPO. Fluid Requirements Calculates IV rate according to the type of surgery. Drug Absorption (Pka) Determines how well a medication will be absorbed into the body. BSA Calculator Calculates BSA according to height and weight. O 2 Remaining in E-Cylinder Calculates how much O 2 is left according to flow rate. Clinical Calculators Pediatric Dose Calculator Converts an adult dosage into a pediatric usingīSA.
The dose of medications infusing such as dobutamine and nitroprusside. Such as nitroglycerin and norepinephrine.
mcg/min ← mL/hr Calculates dosages of medications infusing 1 × Dose, dose/hr ← mL/hr Calculates dosages of medications 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. IV Time Calculator Time ← mL/hr Calculates the duration of an infusion when the rate is known (With or without an IV pump). Calculate infusion rates when given a volume and length of time. IV Rate Calculators Time or mL/hr → gtt/min No IV pump. mcg/kg/min → mL/hr Calculates mcg/kg/min rates (e.g., nitroprusside and dopamine infusions). mcg/min → mL/hr Calculates mcg/min rates (e.g., norepinephrine and nitroglycerin infusions). Dose/hour (e.g., diltiazem), dose/minute (e.g., nitrogycerin), and dose/kg/minute (e.g., dopamine). Dose → gtt/min Calculate drug infusion rates without an IV pump. Example drugs include furosemide, digoxin, and Solu-Medrol®. IV Dose → mL, Dose → mL/hr Calculates single dose IM, IV injections and IV rates if no conversions are involved. PO Dose: Liquids Doses liquid medications such as Tylenol®, Kayexalate® and lactulose. For example, ".3ml/kg." You may first have to convert your patient's weight from pounds to kilograms, then you calculate the total medication volume from there.Medication Dose Calculators PO Dose: Solids Doses solid forms of medication (e.g., tablets, caplets, capsules, lozenges). How do you calculate medication dosage by weight?ĭosages are often listed by how much should be administered per unit of the patient's body weight. Some consider drip and infusion percentage calculations to be more dificult than calculations for solids, liquid oral and injections, so it's important to practice all types of dosage calculations through regular testing and assessment. Mistakes can put patients' lives at risk, so dosage calculations are a key part of patient safety. In order to provide safe nursing care and medication administration, you must calculate dosages correctly. Why are dosage calculations important to nurses? You must calculate, and often convert, the correct dosage to administer a patient. The volume and units that a medication order is written in, is rarely the same volume or units that you have on hand. Remember how hot dogs come in a package of 10 but hot dog buns come in a package of 8? Well, medication volumes and units can sometimes feel like that too - but the stakes are much higher.
