tailieunhanh - Lecture Math for the pharmacy technician: Concepts and calculations: Chapter 8 – Lynn M. Egler, Kathryn A. Booth

Chapter 8, Intravenous calculations, presents information and calculations unique to administering intravenous (IV) medications. After introducing IV solutions, attention is turned to calculating fl ow rates. Students also learn calculations for intermittent IV infusions, infusion times, and infusion volumes. | Math for the Pharmacy Technician: Concepts and Calculations Chapter 8: Intravenous Calculations Egler • Booth Intravenous Calculations 8- Learning Objectives Identify the components and concentrations of IV solutions. Calculate IV flow rates. Calculate infusion time based on volume and flow rate. When you have successfully completed Chapter 8, you will have mastered skills to be able to: 8- Learning Objectives (con’t) Calculate infusion completion time based on flow rate. Calculate volume based on infusion time and flow rate. Calculate medications for intermittent IV infusions. 8- Introduction Intravenous (IV) fluids are solutions including medication that are delivered directly into the bloodstream via a vein Blood is also delivered by IV IV fluids have a rapid effect Are necessary during emergencies or other critical care situations 8- Replacement fluids Maintenance fluids KVO (Keep Vein Open) fluids Therapeutic fluids IV Solutions-Functions 8- IV Replacement . | Math for the Pharmacy Technician: Concepts and Calculations Chapter 8: Intravenous Calculations Egler • Booth Intravenous Calculations 8- Learning Objectives Identify the components and concentrations of IV solutions.
