We sometimes use different pumps to get fluid and medicine into your blood. These pumps often hang on your bed, or on a rack next to your bed. The staff can set these pumps to give you the right amount of medicine, at the right speed. The pumps make beeping noises when the medicine runs out or when the staff need to check anything else. You might also find that the pumps make beeping noises when you bend your arm or move the hand with the plastic tube in it. If they do, changing the position of whichever part of your body the tube is in can help.
