CPR, or cardio-pulmonary resuscitation, is a simple procedure that could mean the difference between life or death for someoneā€”but only if it's performed properly. The procedure can be fruitless if the chest compressions are too shallow, or even dangerous if too heavy. So to ensure that it's always being done properly, Physio-Control has developed a monitor called the TrueCPR that provides precise feedback on how effective the CPR is being performed.

More specifically, it uses a pair of padsā€”one that sits under the patient and a second that sits on their chestā€”that constantly monitors the distance between the two using a magnetic field. This data allows the TrueCPR to provide constant and visual feedback on whether the compressions need to be deeper or shallower, and how often they need to be performed.

The technology behind it is particularly useful since it's just as effective on a soft surface like a bed, where it can feel like compressions are being performed deeper than they really are, or even in a moving vehicle like an ambulance. But the best part is that this isn't just some far-off design concept. The TrueCPR has already been cleared by the FDA and European agencies and is available for sale right now. So here's to hoping it starts showing up next to those emergency defibrillators you see all over the place.
