Having COPD, I’m on four on my oxygen concentrator and two at night. Have tried many different inhalers ending up in the donut hole. Now my doctor has me on two different medications using my nebulizer twice a day.
Just received my one prong cannula. It works just as well as the two prong cannulas. I no longer have the tubing running down the front of me. For women it’s great for looks. One side of my face is completely free of tubing. You can also switch nostrils.
