As the experiment showed, such speakers, equipped with an additional element, are able to catch sounds indicating heart failure, and call an ambulance, writes The Daily Mail. The column determined that a cardiac arrest occurred, in 97% of cases, even if alarm sounds were heard at a distance of 6 meters.

Addition to the columns developed by the University of Washington. Scientists urge to put columns in the bedroom, where most often occurs cardiac arrest. A halt can be judged by the characteristic agonal breathing (observed in 50% of victims) - frequent, superficial, and convulsive. It indicates a decrease in the level of oxygen.

Scientists used audio recordings of such a breath during 162 calls to the ambulance, trying to analyze them using smart speakers, smartphones and special computer algorithms. The assembled system had a diagnostic accuracy of almost 100%. The probability of a false positive diagnosis was 0.22%.
