My husband has just returned home from being in hospital for hernia repair it was herendus as the operation was done under local anaesthetic. The up shot of it is he is now on 16 hour a day oxygen. He had oxygen for exercising. He alway been active even running the London marathon along time ago. My question what happens if you have to go on a long journey. He has liquid oxygen but that does not last for very long. He also has the large consentrator . As we are both new to this 16 hour a day oxygen we would so welcome any tips with getting on with you life as it is a bit overwhelming at the moment.
