Telesimulation, specifically in health areas, is an educational technique that combines clinical simulation and communication technologies. This definition has been constantly modified, but today more than ever it represents a valuable resource to provide academic continuity. The purpose of this chapter is to present the basic concepts of this strategy while reviewing its antecedents/history in the pre-COVID era, the experience with this technique in health sciences, as well as the processes and resources essential to carry it out with an analysis of the potential limitations that may entail. Likewise, concrete examples of telesimulation in various subjects will be shared, leaving readers the challenge of constant innovation in this field.
