0807 trio no longer needed at home

My caregiver and I have figured out a way for me to get enough walking exercise with just the two of us, yet keep me connected to my oxygen tube. We're using a compressor unit that was provided to me to use while at home, so I only need to use the pressurized tanks while moving around away from home. The unit plugs into AC and pumps the O2 through 50 feet of poly tubing (see pic). I use this while sleeping and working inside the house.

We just moved it outside to the patio, turned it on, the proceeded to walk around the backyard while breathing through the tube. Just the two of us. No third person needed, at least for the home exercise portion of my physical therapy. Still need to have three people when moving away from home. But I have two appointments this week that could change that. More on this as it develops.
