Video, How the Tele-ICU Saves Lives, from Yale Medicine. Yale Medicine’s Tele-ICU is  a two-way audio/video system that allows staff to monitor critically ill patients remotely. Live data is fed from the patient’s bedside monitor to the Tele-ICU. If there is a change in the patient’s vital signs, the staff in the Tele-ICU immediately notifies the nurse or doctor on site.
