The dewar contains liquid oxygen and it should only be used by the patient to fill the portable unit when the user wants to leave the house. If oxygen is needed at home, we recommend the patient uses the oxygen concentrator machine.

Users should be familiar with the component parts of a portable home oxygen therapy unit before it is used including:

• To check the level of liquid oxygen in a dewar, press the liquid level switch for at least two seconds and read the liquid level display. Always reorder when it reaches a quarter full.
• If the low battery indicator on the liquid level display lights up when the button is pressed, the user should inform the Baywater Healthcare Healthcare Technician at the next visit.
