Hello everyone, i'm new on here. I've joined because I'm trying to support my brother who has severe COPD. I was wondering if anyone can advise me as to what i can do if i'm out with him and he has a sudden breathing attack? At home he has oxygen, nebuliser and inhalers. Are there any portable oxygen devices or anything else i can do, apart from getting him to the hospital asap? Any advice would be welcome. Thank You.
