Is it possible your air is dry? I have to watch it in the winter. I use a "bubbler" on my oxygen machine

I don't use oxygen but was concerned the switch to QVAR was causing it. I last week asked the doctor and he said if it continues it would be a concern but mine stopped a few months after

It is a small bottle that attaches to the concentrator to put moisture in your oxygen.

Hi Easycook, what is a bubbler??

Hi Dave, I'm on Ventolin and do not have nose bleeds, The doctor changed me to Xopenex HFA, she said it had less side effects then ventolin. Good luck, and ask your doctor about the nose bleeds.
