Imagine this: you're eating dinner with your family and suddenly your left arm feels numb. Your speech is slurred. It could be a stroke, so you've got to get to the hospital fast. But what if your hospital doesn't have a stroke specialist or what if that doctor is out of town? The answer may be telemedicine. Doctors at Mayo Clinic are using a telemedicine robot that allows them to be face to face with patients who are miles away.
