Hi, @pml Yes, she used the kind that makes its own from the air. In our case, she didn’t need O2 until she was in hospice and they provided it as part of her hospice overall ‘package’.

I have had an InogenOne G3 compressor for 5 years and yes, it cost $3000 when I bought it but if you are on medicare I think they cover it now....

I am not having to use it every night which is good for my husband because no way around it but it is noisy! Perhaps the newer ones are quieter now.....
