Paramedic students at McHenry County College used a chilly day in December to practice the skills they’ll be using for the rest of their careers. A simulation of a two-vehicle collision where two cars were totaled, injuring the people involved, took place Saturday in the college’s parking lot. The 21 paramedic students participating did everything they would be expected to do in a a real crash, from handling the dispatch to extricating the “patients” and treating them.
