This document provides instructions for using a drops per minute calculator to determine intravenous drip rates. The calculator allows users to input the volume of infusion, planned time, and drop factor/calibration to determine the number of drops per minute needed. It also provides an advanced mode to view the number of drops per hour. The tool is designed to help clinicians easily calculate drip rates for intravenous therapies and ensures accurate, painless delivery of medications or fluids.
