The hospital sent Respiratory up to his room to inspect and approve the use of his own machine, and they assured me that they would set up the machine for him (this hospital had no overnight accommodations for spouses so I had to go home for the night).
When I returned in the morning, I found that they had hooked up his S9 Climateline hose backwards -- as you can see, the two ends are clearly not identical. They attached the end with the electrical connection to the humidifier to his mask instead,

Good thing they 'inspected and approved' the machine, being the experts on respiratory equipment and all..........
Hospital Respiratory staff -- you gotta luv 'em
