I am finally after two months getting a portable concentrator that is not pulse but continuous. It weighs seventeen pound but comes with w a pull carrier. The pulse one did nothing for me. My physical therapist said it was doing nothing for me during exercise treadmill and etc my 02 wsstill droppinf. Could not get it to sync with my breathing during exercise

@ JudyHarrington when using oxygen tanks you may use a continuous flow or a pulse dose gauge connected to the tank and cannula in your nose, the pulse dose oxygen (1-5) settings comes out as you breathe in through your nose. The continuous flow gauge is set to flow on your setting continuously. You may check with the more knowledgeable people on this site there are many of them. MERRY CHRISTMAS.

what is a pluse concentrater I have a machine a big one that makes oxygen I have a long tube but still

I am on Advair and Incruse,both powder inhalers, also xopenex rescue inhaler, and xopenex nebulizer 4 times a day and oxygen 24/7 and I am on 3 lieters. I still have a hard time I get panic attacks I pick something to look at and do pursed lips breathing it takes a bit but it does work.

I have a problem with pulse as well. If I am short of breath I tend to force the pulse to give more oxygen then I become even more SOB. I still use it though when I run errands. Regular oxygen tanks run out to quickly.
