The only pressurized O2 we would be using is the airline's.
Thanks for the reply.
If you need longer power, you can rent(hire) battery pack with 110V (220V on your side of the pond). One big user of these "power pack" are photographers who need to power their lights. London area professional photo equipment rental shops should have some.
One of these should be good for TLV LHR to US.
Some seat have built in power but the amperage is limited and it is not available in all seats.
I have been a professional photographer for 15 years. I am also a CPAP user because I suffer from sleep apnea. I have a battery powered 110V powerpack which is legal for in flight use that will power my CPAP unit for some restful sleep from North America to Asia over the Pacific.
This is what I use, they have a 230V Europe version. I am sure there are others available locally.
