-Up to eight simultaneous drips -Live results, rounded to two decimal places -Dextrose presets for D5, D10, D12.5, D15, D20, and D25 -Solve for rate: pick a target GIR and concentration and get the mL/hr, with the option to account for drips already running -Light and dark themes, eight accent colors, fourteen font choices, and adjustable text size -No account, no ads, no data collection. Everything stays on your device. Formulas GIR (mg/kg/min) = Σ (% dextrose × mL/hr) ÷ (6 × weight in kg) Total fluids (mL/kg/day) = Σ mL/hr × 24 ÷ weight in kg Glucose Infusion Rate is a calculation aid for licensed healthcare professionals and does not replace clinical judgment, institutional protocols, or verification of orders.

NICU medical staff oversee the care of our most precious and delicate new citizens. It is a profession that requires precise calculations, and unfortunately those calculations could be subject to human error. With the NICU Calculator app, errors will be greatly reduced. This will help NICU medical professionals better serve their patients. The NICU Calculator will also speed up daily work rounds, allowing more time for critical cases and patient care. This calculator was made and designed with the support of NICU staff who perform these calculations daily. The NICU Calculator performs the following calculations: Fluid Calculator: Exact fluid management is important for infants in the NICU and we created a calculator to help calculate total fluid, TPN, intralipid, and feeding rates. It also helps calculate TPN components such as GIR, dextrose percent, percent amino acids, protein, and intralipids. Extra function also allows you to take other fluids patient is taking into account such as feeds, medication drips, blood products, and medication/flushes. Calorie Intake: Knowing how many calories you are providing to a premature or ill newborn infant is important in regards to their growth and overall well-being. We created a calculator that allows you to determine how many calories you are providing in the TPN and feeds given. Glucose Infusion: This calculator allows you to determine the individual and total fluid volumes and glucose infusion rates (GIR) given to an infant when they are on individual or multiple infusion drips. Ca/Phos Calculator: This calculator allows you to determine the amount of elemental calcium and phosphorus given to a patient when using calcium and phosphorus salts. It also helps convert between commonly used units and determines ionized calcium: phosphorus ratio needed to determine appropriate dose for daily intake. Gestational Age: Allows you to calculate corrected gestational age and days of life using date and gestation at birth. Umbilical line/ETT: Calculates umbilical catheter size, umbilical artery catheter length, umbilical venous catheter length, intubation tube size, and intubation tube length based on the weight of the baby.
