There was a bang then loud hissing!

It doesn't sound like a very good hose to keep as a spare.

$20-25 on Amazon could have you a new hose by tomorrow.

Get it here free from the NHS.  I say free, but we all pay for it through taxes, that is why it annoys some people with the influx of workers from Europe, they have paid nothing towards their health care or welfare payments.
I think this is why it was voted to leave the EU, but they kept it anyway

I am not political motivated.

Back to Sleep2snore at least in my Dreamstation the auto off function has to be turned on for it to
to turn the machine off if you take the mask off or like you had the tube come off. I even saw a short
post be a DR. advocation leaving this function turned off because the machine may occasionally read
a long clear airway event as you taking the mask off. Now of all the crazy places to get a cpcp hose
in the USA you may want to check out Home Depot. You have to order on line then have it shipped to your
local Home Depot but heck the price is right at only $ 4.30 plus tax.
