College classes are typically pretty talkative environments, especially for Emily Kelsey and the rest of her classmates in their third year of nursing school at the University of New England in Portland, Maine.

Beneath the goggles, Kelsey and her classmates are inside a virtual reality hospital room sitting with a patient who is having trouble breathing.
