While the applications of just-in-time training are more and more spread, the ubiquitous mobile technology has not found
practical uses of this training strategy. As an original example of services for healthcare, we present in this work an
application of eTraining that makes use of mobile telephones to transmit medical and on-site information content to
emergency medical personnel that attend and emergency. The state-of-the-art in related technologies, overall architecture,
and functioning of JITTER (for Just-In-Time Training for Emergency Responders) is described in this work.
