At 580 watts... No.  it won't.  
It will run for a couple minutes at best.

Even with a new battery the APC BN1500 can run a max of 7 minutes with a load of 580 watts from the charts on APC's web site specs for that model.

This is not the right product for a heavy load like that.
It's a decent UPS but not intended for a large electrical load.

Other options include getting a much larger, dedicated backup with deep cycle batteries or perhaps bottled oxygen for use in emergencies.

Medical grade battery backup that can run for 8 hours costs $2500 for example out of the few I looked at.  They cost a lot more because they are far more powerful and can go for several hours or days in some cases.

Powerful battery backup like that are physically larger that can run quite a while often weigh 40lbs or more.

There are many to pick from and you need the real deal.   
APC battery backups are intended for small loads like a computer.

A UPS at this price point will run itself down in 1 -2 hours even with no load due to internal losses.

They can be very handy for WIFI or your Internet router during a power outage, but products that draw a heavy load like an O2 purifier need a much higher capacity.

Not recommended. UPSes are designed for short power events, not sustained loads, especially that high.

I would suggest a generator or large battery power bank.
