HVAC Controls Technician here. I have experience working on these rooms as well as ERs and just general hospital work as well.
Whatever this study is it is most likely a very specific problem. The sensors and programming I use or have seen installed by others can in no way be faked by some malicious noise.
I would have a physical sensor in the room, another outside the room somewhere both reading building pressure, do the math and verify the room is negative. I would also have a sensor reading CFM (cubic feet per minute of air movement) from outside in to ensure the correct amount of air exchanges is happening. As well as the other various sensors that monitor exhaust fan status and supply air fan status I can't see how it can be effectively attacked. If one of those sensors failed, or was reading incorrectly the facilities crew that deal with the HVAC would be notified and it would be investigated immediately. Doubt this would throw the area into chaos either.

Almost feel like I'm reading an onion article.
