A liquid oxygen dewar should last 4-6 weeks with normal use. The Baywater Healthcare Healthcare Technician will arrange a delivery schedule with the oxygen user taking into account usage and the length of time the dewar will last. However, if any issues arise in the meantime, the user should call Baywater Healthcare Helpline on 0800 373580, 8.00am – 6.30pm.
If the portable unit does not separate easily, do not use force, the units may be frozen together. Wait until they warm up, they should then separate easily. Never touch any frosted parts. If liquid leaks after separation reattach the portable unit to the dewar immediately, then try again.
If there is excessive leakage to the point that there is a stream of liquid, leave the area and call Baywater Healthcare on 0800 373580 immediately.
If refilling the portable unit immediately after a period of use, fill it and then wait 10 minutes with the flow control (K) set at zero. Then operate as normal.
How to use a portable unit
- Push the nasal cannula firmly onto the oxygen outlet connector (H)
- Put on the cannula
- Turn the flow rate control (K) on top of the portable unit until the prescribed flow rate is visible in the flow rate window (N) and it clicks into place.
- The oxygen level should be checked frequently, especially when using a portable unit away from home.
- To turn the portable unit off, turn the flow control (K) anti-clockwise to the off position
Always use a portable unit in the upright position. If it falls over or is laid on its side, the oxygen will vent very rapidly and make a loud chatter. If this happens simply return the portable unit to its upright position.
Never cover the portable unit or carry under clothing.
When using the portable unit in the car:
- 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 unit in the boot of the car
Checking the portable unit batteries (Spirit 600 only)
The green light on top of the portable unit will light up with each breath, showing that the portable unit is delivering oxygen. When the light is red it means the batteries need replacing. The unit will continue to deliver oxygen while the red light shows.
The green light will show with each breath even if the portable unit is empty
