Med Math Calculator

Step-by-Step Guide to Using the Medical Mathematics Calculator

Step 1: Enter Patient Details

Begin by entering the patient’s information. Specifically, you need to input the Patient Weight (kg). Ensure that the weight is a positive number ranging from 0.1 to 500 kg.

Step 2: Input Drug Details

• Prescribed Drug Dose (mg): Enter the prescribed drug dose required for the patient. The dose should be a number greater than or equal to 0.1 mg.
• Drug Concentration (mg/mL): Enter the concentration of the drug, ensuring it is a positive number starting at 0.1 mg/mL.

Step 3: Enter Infusion Information

• Infusion Rate (mL/hr): Provide the rate at which the drug should be infused. The rate must be a positive value beginning at 0.1 mL/hr.
• IV Set Drip Factor: Select an appropriate drip factor from the dropdown options available: 10, 15, 20, or 60 gtt/mL. This selection is required to determine the correct drops per minute.

Step 4: Calculate the Results

Once all inputs are provided according to the criteria specified, the calculator will compute the following:

• Dosage per Kg: Determines the drug dosage distributed per kilogram of the patient’s weight. It is calculated using the formula drugDose / patientWeight and displayed in mg/kg.
• Volume to Administer: Calculates the volume of the drug to be administered using the formula drugDose / drugConcentration, shown in mL.
• Drops per Minute: Computes the number of drops per minute required using the formula (infusionRate * dripFactor) / 60. The result is in gtt/min.
• Total Drug per Hour: Provides the total amount of drug delivered per hour, calculated as infusionRate * drugConcentration and presented in mg/hr.
• Concentration per Kg: Displays the drug concentration per kilogram of weight, using the formula drugConcentration / patientWeight, given in mg/kg/mL.

Ensure all input values are entered correctly to avoid errors in calculations. Review any output values that seem inconsistent to ensure the initial data was precise.
