Precautions while using Oxygen Therapy
You need to be informed about how to use your equipment safely and correctly. Do not accept delivery of unfamiliar equipment until your oxygen supply company has taught you how to use it. Check the label on every oxygen container before you use it. Liquid oxygen should have Oxygen Refrigerated Liquid U.S.P. on the label. Compressed oxygen cylinders should have Oxygen Compressed U.S.P. on the label. If the label of a container reads differently, do not use the container. Call your oxygen supply company immediately. Keep a new tank of oxygen available at all times. Even if you use an oxygen machine (concentrator), you will need the tank for leaving the house and during power failures. Have a back up oxygen system to use in an emergency.
