@RobinSpadeTaylorDahm, I hear what your saying Robin, I always get a shopping cart for the exact same reason as you. Most item of clothing I have has pockets, that way I can put essentials in my pockets and not a carry a purse, just oxygen, because, it is heavy.

When you cant breathe its hard to even tote the oxygen you need! I have to shop at places that have carts to hold my poc and purse and also to lean on! I know people think I am lazy, but I always leave my shopping cart by the disabled parking for others to use without walking to get one. I know I appreciate it when there is a cart right there!

I am on oxygen 24/7 I use the big floor model at home it will go all over my house and I have a carry tank that is an 8 our task that I can carry in my hand or it has a pouch I can hold it on my shoulder. The tank has both free flow constant air or I cN switch to pulse which you can hear every time I take a breath

I have a portable Simplygo mini, they say it is 5 pounds, but once you put the battery in its 10. It is a lot easier for me though. I plan on getting a backpack as it is easier to carry.

I also am on oxygen 24/7 I have the one that plugs in the wall too but is rented for going out I use the m9 tanks (c size ) put them in a back pack I just buy a hydration pack for hiking and take the water pouch out and put my tank in works great
