OT: It's a new track record; for hours

I'm looking at a patient's Respironics PR1, version 1, and this thing is filthy with dust, totally coated inside. It looks like somebody was sanding drywall while it was being used. Then I look at the hour meter, 32,745 hours, holy cow! I was first patient critical because it was so dusty, but now I'm amazed.

if it walks like a duck and looks like a duck...... maybe they were using it as an inefficient dust mask during the day and sleeping with it at night. I'm sure people have thought of stranger things to do with it.
