LOX Flasks
LOX flasks are refillable home oxygen therapy portable units designed to provide a source of oxygen to help the patient get out and about for longer periods of time. The LOX flasks should be filled from the large LOX dewar. All durations listed are approximate and will be affected by the patient’s breath rate.
As with all home oxygen therapy equipment, you should become familiar with the parts of the LOX flasks before use.
Travelling with portable LOX flasks
When using the portable LOX flasks in the car, you should:
- Always drape the portable shoulder strap over the front seat headrest
- Always open the car windows slightly to keep the car well ventilated
- Never keep the portable LOX flask in the boot of the car
Note: The green light will show with each breath even if the portable unit is empty.

Checking the Spirit 600 LOX flask batteries
