  1. How easy are these symbols to learn? Nurses and doctors use machines to give medicine to their patients. The people who design the machines (computer scientists) use symbols to make them easy to use. Some symbols give information about the machine (its status), some tell you how to control it. The machines are called ‘infusion pumps’. The medicine is pumped from a bottle called an ‘infusion bottle’ into the patient using a syringe. Below are real symbols used on infusion pumps. It is very important that nurses and doctors understand the symbols so they don’t make mistakes that hurt their patients. You must learn the following symbols and their meaning, and answer the questions overleaf. The chi+med project is helping make medical devices safer – you can find out more about us at the website below. cs4fn.org/chi-med / www.chi-med.ac.uk/misc/resources.php
