Mine is the Resmed AutoSet II and includes the mask, hose & power cord.

The cpap, medication, laptop, camera and odds & ends all fit in my
Tenba Messenger bag that is 17.5W x 12.5H x 5.5-8.5 in.

The above is my carry-on... everything else is checked.

When purchasing the Tenba I dragged everything I wanted to fit in a
bag to a camera store with a huge selection of bags... and test fitted
the items I wanted to take into a variety of bags before settling on
the Tenba.

Mom, who is 84, always books flights with "assistance" and never
has issues when boarding a flight as the FAs are always helpful
getting her situated. She is mobile, just cannot walk the long
distances in terminals... like DTW for instance.
