It really doesn’t make a difference what brand your pulsed machine is . I hear many say they have to stop and rest a bit often while using a portable concentrator. They are handy and kind of discrete. They are noisy tho. That kind of ruins any
incognito. . If you are using a portable pulse, ( first remember they can not produce over 3 ltrs per. The 1-6 speed on them means nothing . If you are having to stop rest and go, then you are harming your body. Not just having SOB. It has negative effects on your body. When your oxygen drops below say 90%. Then the damage starts. When you get it back over 90 your body gets back to function better . Just how many times are you going to do these short episodes of harm ? They add up and will shorten your survival of this disease. It’s not about if you can tolerate the SOB for short intervals. It is harming you.
