Most emergency medical training involves lifeless torsos, videos, and noninvasive simulated work on a live partner in which you haphazardly  practice what you would actually have to do in an emergency situation. From my personal experience of many CPR classes as well as a course of emergency medical training, I can attest none of this prepares you very well for what you would actually have to act out in a life threatening situation. No, you can never fully prepare for having to rescue someone, but what gives you the confidence to do it is practicing something similar prior to having to act on the spot.

Kernerworks has developed a realistic robotic mannequin that breathes, bleeds, and responds to procedures to give feedback if they have been performed correctly.This company in San Rafael, CA includes a team of former special effects artists that used to work for film studios. The mannequins were molded from real people, given realistic features, and have an internal computer system that includes sensors which respond to procedures.

Used for military training for trauma response, one of the products is a double amputee mannequin which allows trainees to practice relieving pnueumothorax with a needle (sensors respond if done correctly). One of the features is also a well developed throat which features air differential sensors. Medics can practice placing a laryngoscope into the throat which has a camera so you can see the placement of a tube for breathing. An endotracheal tube can be placed in the throat for use of an Ambu bag, if done correctly this shows the chest rising. If it is done incorrectly and the tube is accidentally placed into the esophagus, the chest will not rise. Unlike most practice torsos, these are sensors responding to these procedures, which are much more precise. Watch the video above for a tour Tested shared which explains more about the company and the incredible work behind the mannequins.
