Was wondering what anyone might think about this. Need my POC for going out and don’t like pulling those carts around but to get the proper O2 I need a larger POC, then it’s to big and heavy so for now I use my normal POC but also wear another canulla and use a little m-6 tank to bring with when walking. Then when sitting or hanging out I turn the tank off. Thought COPD was bad, then going on oxygen was bad, now on it 24/7 forever is bad. Didn’t think it could get worse until I put the second device in. One cord is enough, but two. One tangles around the other and the both tangle each other and twist, double ear pressure, now I can handle anything. Went out the other day with just one. My POC, man I almost felt free, one was a breez.
