I am thinking that the best way to keep a sterile environment is to introduce it. Blow sterilized air actively over the operating field, just enough to provide a positive pressure compared to the room air.
This has the added advantage of helping give a direction to any floating blood. You could even place several intakes near the field, with filtering to catch the blood and any other floating particles.
Sterilize the air and feed it back to the output vent(s) and you have a closed loop that maintains sterility and won't mess with the air pressure of the sealed station.
I was that kid, or at least one of them. A little nerdy kid in glasses who didn't know enough not to show he was smart.
Every day of grade school I would get tormented until I would break down crying and I had nothing that I could do (I tried fighting back once or twice but it just made things worse). The abuse and the complete powerlessness to do anything about it (no adults would help either) led my to a pretty severe mental breakdown in 4rth grade (crying for half a day stuffed back in a corner between an immovably large map cabinet and the wall with teachers trying to coax me out). So I got put in a different school, but then when I got to middle school where both grade schools fed to, I found all the old tormenters who remebered me and started up again.
I found a way out, I just stopped caring. For the most part I stopped talking to people and retreated into books and video games. This socially crippled me and pretty much destroyed my life until I started rebuilding it in college. (Yes, I learned how to socialize from the role playing gamers, sad but true).
I think the only thing that saved me from being one of the rash of school shooters is that I had never heard of it. This truly frightens me, that I can see a place in my early life where I would rather have some sort of revenge and die than go on living in torment. Watching the videos that the columbine shooters made, I can empathise with what they are feeling and why they are acting because I had been there too. (I certainly don't agree with their actions, or approve.)
I am glad that I was not 5 years younger. I am glad that I found another way out (even as crippling as it was) that wasn't suicide, alchohol, drugs, or revenge killing.
So you get your child a cell phone because you want them to be able to call if they get in trouble, but then you set a tracker on it, so they end up leaving it at a friends house while they both go off somewhere else. Not so smart.
"Hey tommy, can you hold on to my phone while I go downtown for some crack? I don't want my parents to know I was in that area."
The first time a kid gets chewed on for going "out of bounds" is the last time they carry the phone with them....
