Yes, you'll probably be safe. Is "probably" good enough for you or your loved ones?
Since the 2000 (I think) Edition of the National Electrical Code, arc fault circuit breakers have been required in bedroom circuits. If the home has those then there won't be a "leak" problem as the AFCI will trip. They are exceedingly sensitive.

We all live our lives based on "probably" being safe. If we demanded to be safe with 100% certainty we couldn't live. We all run the risk of dying in a car crash. We have a risk of MRSA any time we visit someone in a hospital. We risk salmonella poisoning every time we eat. We risk skin cancer from sunshine every time we go outside. I could go on and on but you get the point. Archangle, I don't think anyone of us on this forum denies the possibility of dire consequences of some of our actions as you so love to give discourses about. We don't mind being reminded occasionally about the possibility of a failure. But what we get tired of hearing is your constant harping as if a possibility is in fact a certainty. Life is fraught with risks. Nothing is certain, not getting killed, not getting sick, not living to 100, not dying from a mosquito bite, nothing. So please, go ahead and give us a scenario that might could happen, but for God's sake stop telling us it is likely to happen. Now, if you have reliable objective statistics to back up a claim that some action has a probability of 20%, or 80%, of occurring then feel free to give us those statistics.

It's going to have to be.

"Probably" is the most certainty any of us will ever get when it comes to safety.

No. Arc fault circuit interrupts do almost nothing at all for the scenario I'm describing. AFCIs are designed to prevent fires from sparks, not to prevent electrocution. Ground Fault Circuit Interrupters are the type that helps prevent electrocution. GFCI's are not generally required in bedrooms.

http://www.cpsc.gov/cpscpub/pubs/afcifac8.pdf "AFCIs vs. GFCIs
The AFCI should not be confused with the GFCI or ground fault circuit interrupter. The
GFCI is designed to protect people from severe or fatal electric shocks while the AFCI
protects against fires caused by arcing faults."

I have used this: http://paulcbuff.com/vm120.php product many times with my Resmed S9 Auto WITHOUT the humidifier while camping. You can even get an extra battery and hook them together for additional runtime. I use one battery which usually lasts all night at my pressure and recharge it from my car in the day with a cheap inverter plugged into the lighter socket.
