First night back home with my shiny new oxygen tank. The portable unit my wife brought to the hospital for me to go home with ran out of battery 5 minutes before we got home( it’s an hour + to hospital and same back plus a pharmacy stop). I had to walk into the house w/o oxygen at that critical time, which caused some distress but the home unit was up and running immediately and was it was good to be home. First night was not uncomfortable just a few minor issues. Today I have a immunotherapy appointment and will discuss my chemo reaction and hospitalization, review the last PET scan and what mods will be made to prevent this from happening again.
