Most 02 concentrators have a place where water can be made available to add humidity to the 02. If you can't figure out your concentrator, call your DME and ask for them to deliver and install the proper equipment for you.

Ronald2 how is that Breztri working for you? If yo are renting the concentrator the company will bring you out a container thats hooks up to the concentrator. Your hose will hook up to the container instead of the machine, I have one also. Make sure you just put distilled water in it.

Do you have a humidifier? When my late aunt was on oxygen, she had the same problem until my sister equipped her with a humidifier because oxygen was doing the same thing to her.

Do the have you on a rescue inhaler. I was wheezing today and use it.

Today was 1st day using it with a holding chamber, could tell a difference! I think I was inhaling too fast n hard, can't now or I get a whistle!!
