ICU eavesdropping

Our redoubtable night shift charge is fond of challenging us to think outside the box. On the question of patient/family complaints about noise, he had this to say:

Pretend you're not a nurse. Walk down the hall, stop and listen outside of each room for a moment, then move on.

Some results:

1. "Don't put that thing in there!"
2. "Squeeze!"
3. "Work it!"
4. "Suck it in harder!"
5. "Blow blow blow blow blow!"
6. "Yes, you do have to do that."

There was nothing inappropriate going on in any case, but feel free to guess what the actual situation is. I'll post the real answers tomorrow.
