Hi, I’ve been using Inogen pulsed Oxygen for the last 5 months, but last week at my Hospital appointment my SAT’s went down to 73% doing the 6 minute walk test even when using INOGEN.
I now need Long term oxygen but although I know about the portable small cylinders for when you are out and about I’m unsure what you have indoors.
I’ve read about concentrates etc but have no idea what they are.
Please can you help explain the different forms?
