Calling Emergency Services: Smart Speakers Can Detect Heart Attacks

Calling Emergency Services: Smart Speakers Can Detect Heart Attacks: Researchers from University of Washington have recently developed and artificial intelligence (AI) tool that is going to allows smart speakers to identify the signs of a heart attack or cardiac arrest, along with alerting emergency services also to friends and relatives.

Now you can say that smart speakers, as well as smart assistants, are not just merely for commanding it to play music or tell you the weather condition or to book an Uber for you.

In the recent research which is published in NJP Digital Medicine, researchers Justin Chan, Thomas Rea, Shyamnath Gollakota as well as Jacob E. Sunshine stated that the technology was capable of detecting agonal breathing 97 per cent of the time from up to 20 feet away.

The researchers also said that they track down the recording samples of pre-heart attack or pre-cardiac arrest agonal breathing from the 9-1-1 emergency calls in the middle of the years of 2009 to 2017, from the Public Health-Seattle & King County, Division of Emergency Medical Services.

The researchers said, “For each occurrence, we extract 2.5 seconds worth of audio from the start of each agonal breath. We extracted a total of 236 clips of agonal breathing instances. Given the relatively small size of our agonal breathing dataset, we augment the number of agonal breathing instances with label preserving transformations, a common technique applied to sparse datasets. We augment the data by playing the recordings over the air over distances of 1, 3, and 6 meters, in the presence of interference from indoor and outdoor sounds with different volumes and when a noise cancellation filter is applied.”

The indoor as well as outdoor sounds may possibly comprise of the noise made by air-conditioners, pets and also the traffic movement outside. This dataset also comprised of 162 calls, approximately nearly 19 hours of clear recordings of agonal breathing. Right now, at this moment the tool is in the testing phase and it can possibly be activated on smart speakers which are commonly similar to how an Amazon Alexa speaker can assist a skill, and is going to detect the breathing patterns of the users.

The recordings were captured on various other devices that comprises of an Amazon Alexa smart speaker, an Apple iPhone 5s as well as a Samsung Galaxy S4 in order to get 7316 positive samples.

Agonal respiration also known as gasping respiration or agonal breathing is basically an abnormal pattern of breathing as well as brainstem reflex which is considered by gasping, labored breathing, go together with by strange vocalizations and myoclonus. It is also one of the symptoms of cardiac arrest. Agonal breathing is an extremely serious medical sign that requires immediate medical attention and if at that crucial time if they are alone then it might be certainly impossible for them to seek help. Agonal respiration can progresses to complete apnea and heralds death, if not getting the proper health care immediately.

While we’re on the subject, this procedure is going to run on the processors built inside smart speakers as well as will function locally. The researchers in addition want to tune the algorithms to eradicate the false alarms.
