Keywords
💡IV calculations
IV calculations refer to the process of determining the infusion rate, time, and other parameters related to the administration of intravenous (IV) fluids. In the video, the nurse explains how to calculate these parameters using specific formulas and conversions, which is essential for healthcare providers to ensure correct and safe delivery of medication or fluids to patients.
💡Completion time
Completion time is the estimated time when the IV infusion will be completely administered to the patient. It is crucial for healthcare providers to calculate this to monitor the patient's treatment progress and plan subsequent care. In the video, the nurse demonstrates how to calculate the completion time by adding the infusion duration to the start time of the IV fluid administration.
💡Flow rate
Flow rate in the context of IV therapy refers to the speed at which the fluid is delivered to the patient, typically measured in milliliters per hour or drops per minute. Adjusting the flow rate is important to ensure the correct dosage of medication or fluid is administered as prescribed. The video provides a detailed methodology for calculating the flow rate based on the ordered infusion rate and the drop factor of the IV tubing set.
💡Drop factor
The drop factor is the number of drops of fluid delivered per milliliter through the IV tubing set. It is a critical parameter in IV therapy as it directly affects the accuracy of the fluid administration. The video emphasizes the importance of knowing the drop factor of the IV tubing set to perform accurate calculations for the flow rate and infusion time.
💡Dimensional analysis
Dimensional analysis is a mathematical method used to convert and compare different units of measurement. In the context of the video, it is employed to convert the infusion rate from milliliters per hour to drops per minute, which is necessary for calculating the IV flow rate. The nurse uses this method to systematically set up and solve the problems, ensuring accurate and consistent results.
💡Infusion time
Infusion time refers to the total duration for which the IV fluid is administered to the patient. It is a critical aspect of patient care as it helps in determining the total time the patient will be on the IV and helps in planning the nursing care schedule. In the video, the nurse calculates the infusion time based on the total volume to be infused and the flow rate, providing a clear timeline for the treatment.
💡Military time
Military time, also known as 24-hour time, is a timekeeping convention where the day runs from 00:00 (midnight) to 23:59, and hours are not divided into AM and PM. It is used in healthcare settings, including the video, for precise timekeeping, especially when calculating completion times for IV infusions that may run over midnight.
💡Conversion table
A conversion table is a reference tool that lists equivalent values of different units of measurement. In the video, the nurse uses a conversion table to determine that 1 hour is equal to 60 minutes, which is necessary for converting the infusion rate from an hourly basis to a per-minute basis for further calculations.
💡Start time
The start time is the initial point at which the IV infusion begins. It is important for tracking the duration of the infusion and determining the completion time. In the video, the nurse uses the start time, along with the calculated infusion time, to find out when the IV bag will be empty.
💡Total volume
Total volume refers to the entire quantity of fluid that is to be administered through the IV infusion. It is a fundamental piece of information required to calculate the infusion time and ensure that the correct amount of medication or fluid is given to the patient. The video script provides the total volume for each infusion problem, which is then used in the calculations.
💡Rounding
Rounding is the process of adjusting a number to the nearest whole number, often used in calculations to simplify the result or to conform to standard measurement units. In the context of the video, rounding is applied when calculating flow rates and infusion times to obtain whole numbers that are practical for healthcare settings.
Highlights

Nurse Sarah introduces a video tutorial on solving Intravenous (IV) calculations, specifically focusing on completion time and flow rate.

The first problem involves infusing 1500 milliliters of fluid at a rate of 100 milliliters per hour with an IV tubing set having a drop factor of 20 drops per milliliter.

Dimensional analysis is used as the primary method for solving the IV problems, which involves converting and canceling out units to find the required values.

To calculate the flow rate in drops per minute, the video demonstrates converting the infusion rate from milliliters per hour to drops per minute using the given drop factor.

The calculated flow rate for the first problem is 33 drops per minute, using the formula: (100 mL/hour * 20 drops/mL) / 60 minutes/hour.

For determining the infusion time, the total volume, flow rate, and drop factor are utilized to find out how many hours and minutes it will take to infuse the entire volume.

The completion time of the IV bag is calculated by adding the infusion time to the start time, accounting for date changes if the infusion spans over multiple days.

The second problem in the video involves infusing 2 and 2 liters of fluid at a rate of 125 milliliters per hour with an IV tubing set having a drop factor of 15 drops per milliliter.

The calculated flow rate for the second problem is 31 drops per minute, using the formula: (125 mL/hour * 15 drops/mL) / 60 minutes/hour.

The infusion time for the second problem is determined to be 20 hours and 10 minutes, using dimensional analysis with the given volume, flow rate, and drop factor.

The completion time for the second IV bag is calculated to be 18:25 on 4/15, taking into account the start time and the infusion duration.

Nurse Sarah emphasizes the importance of accurate calculations to ensure correct IV infusion times and completion times, which is crucial for patient safety and proper medication administration.

The video provides a clear and detailed explanation of each step in the calculation process, making it accessible for viewers to understand and apply in a clinical setting.

For additional practice, Nurse Sarah offers a free quiz on her website, accessible via a link in the video description, for those who want to further improve their IV calculation skills.
