6 | When the portable is full, close the |
| valve. You will know that it is full |
| when the hissing sound changes |
| tone, and some liquid comes out of |
| the vent line. |
7Lift the portable off of the VIAspire Liquefier.
If the portable does not separate easily, do not use force. The VIAspire Liquefier and Portable may be frozen together, which sometimes occurs. A slight twisting motion will release them.
•Wait until the units warm up for 3 to 5 minutes, and then they will separate with slight effort.
•Do not touch any frosted parts.
•If any liquid is leaking from the liquefier reservoir or the VIAspire Portable after separation, reattach the portable immediately, then separate the units again.
•If liquid continues to leak, leave the units connected and call your medical equipment provider.
8Close the Coupler Access Door. After a short period of time, the VIAspire Liquefier will begin liquefying to replenish the liquid oxygen level.
WARNING Should any excessive leakage occur, to the point that a stream of liquid is present, leave the area and call your medical equipment provider immediately.
WARNING Liquid or cold gaseous oxygen can cause frostbite on the skin. Oxygen will result in increased fire hazard.
NOTE For additional information and instructions on proper use of your VIAspire Liquefier, refer to the user guide that came with it.

Selecting the Oxygen Delivery Mode
The VIAspire Portables 300 and 600 automatically dose in two modes of pulsed oxygen delivery as well as continuous flow modes.
When you are resting and your breath rate is slower, the VIAspire Portable 300 and/or 600 are designed to deliver oxygen at the lowest flow rate possible. This minimizes nasal dryness and also results in quieter therapy. If you notice a change in the velocity of oxygen on each breath, or a quieter delivery of oxygen, you have probably slowed down your breathing pattern and the SmartDose Technology has adjusted the flow of oxygen to the appropriate level.
Sport Delivery Mode with SmartDose technology
The VIAspire Portables 300 and 600 have SmartDose tech- nology, which will track your breath rate to determine if you are exerting more energy and therefore may need additional oxygen. When you are at rest, the VIAspire Portables 300 and 600 will deliver a resting volume of oxygen. As you begin to exert, your breath rate will climb, and the portable will deliver additional oxygen.
While many oxygen portables require the patient to turn the oxygen flow rate selector knob up and down as they move and rest, the VIAspire Portables 300 and 600 will adjust oxygen volumes to your needs automatically.
