In most of my CPR courses I'm asked how effective the Heimlich maneuver is. We can practice where to place our hands, but this is not a skill that can be practiced on someone who is not choking and is not easy to practice on a CPR mannequin.
But today I found this really neat product and video.
This would be an easy and effective way to teach proper hand positioning and technique. Unfortunately for me it is a bit cost prohibitive. But I wanted to share the video as it is a good training aid just to see how effective proper hand placement and technique are to successfully relieve choking.
