Precautions while using Oxygen Therapy
Using and maintaining tanks
Be sure to know how to turn the oxygen on and off, and set the flow rate. Check the tubing if you are not sure the oxygen is coming through the tube. Look for kinks, blockages, or to see if the tubing has become disconnected from the oxygen container. Also check if the oxygen is turned on. Use a water based lubricant, rather than petroleum jelly, on the lips and cheeks.
