I was going to ask this as well. Why does this PC need to be connected to the internet? If it doesn't need to phone home while operating as a heart monitor then there is no need to have antivirus or have this PC connected to the internet.
Also, plenty of devices not connected to the internet run Windows: ATM's, Billboard, Monitors, etc.

Dumb IT is to blame for this mistake.
