VIAspire Liquefier:
The convenience of liquid oxygen in the home
The VIAspire Liquefier makes deliveries a thing
of the past because it works right in the
patient’s home, converting gaseous oxygen from
any OSD concentrator to a supply of liquid
oxygen that the patient can use to fill a VIAspire
Portable. The VIAspire Liquefier typically runs for
four to six hours per day, liquefying up to 2
liters of liquid oxygen per day. That’s 3 to 4 fills
and more than 12 to 16 hours’ worth of liquid
oxygen readily available, so the patient can dock
the portable to the Liquefier, fill, and go at a
moment’s notice. And because liquid oxygen can
easily be created in the home, the VIAspire
Liquefier means freedom from the constraints of
a delivery schedule and time-consuming cylinder
fills.
How much electricity does it use?
The VIAspire Liquefier runs only when needed
then switches to monitoring mode after the
liquid oxygen reservoir is full. Recent studies
show the Liquefier uses approximately $10.00
more in electricity per month than most
concentrators.
SmartDose Technology:
The power behind the VIAspire system
Only the VIAspire Personal Oxygen System features the VIAspire Portable with SmartDose
technology. Patient tests show SmartDose technology helps maintain higher saturation levels than
continuous flow and fixed dose devices. As a patient’s respiratory rate increases, a proprietary and
patent pending algorithm detects the change and increases the oxygen dose. And the VIAspire
Portable always delivers oxygen at the leading edge of inspiration—where it’s utilized best and
needed most, allowing all-day portable use and greater patient freedom.
“It is…important that the ambulatory device being used is capable of delivering higher doses of
oxygen than what was required during in-home resting use.” —Patrick J. Dunne, “The LTOT Continuum,”
