Abstract: An information technology system for a health care environment is disclosed. Health care instruments transfer medical data to wireless access points. Mobile user interfaces transfer user instructions to the wireless access points. Identity tags transfer identity information to the wireless access points. The wireless access points transfer the data, instructions, and information to a server system. The server system processes the medical data to generate display data and processes the user instructions to generate control data. The server system transfers the display data and the control data to the wireless access points. The wireless access points transfer the display data to the mobile user interfaces and transfer the control data to the instruments. The user interfaces control their displays responsive to the display data. The instruments operate responsive to the control data.
