I have a fear that my CPAP machine will die one day while I'm away from home, such as vacation overseas or during a business trip. I literally no longer can sleep without it, I have anatomical sleep apnea (perfectly fit), but it's quite severe (79 AHI).

I've had a CPAP part failure when I traveled - I used a Dreamstation Go with its special 12mm tubing. The tubing split and I had a hell of a time finding replacement 15mm tubing in the city I was in. I stopped into a random durable medical equipment supplier and went "heyyyyy can I buy a hose I'm really screwed right now!" and they just slipped me a new hose out the back door and shook my hand. Then I had to have a friend 3D-print me a hose adapter... field-expedient medicine is fun.
My current travel setup is now designed to accept as many standard parts as I can ('standard' 15mm tubing available at Walmart/Walgreens/CVS, a 'standard' CPAP mask, and the machine is adapted to use USB-C Power Delivery so I just need a 100W PD source or better to run everything (even battery).
