They have developed an artificial intelligence that can detect heart failure immediately without contact with the body. Install on the Alexa speaker or any other voice assistant.
The development of artificial intelligence that can detect heart failure without leaving home has opened up a new avenue for the relationship between disease and diagnosis.
It is not the first to move in this direction.They have developed detectable sleep apnea Start with cell phone and opioid overdose.
These systems are based on a similar process, where hardware is installed in the Alexa speaker (or any other intelligent voice system) that emits a signal similar to sonar. These signals bounce off your chest and return to the speakers as echoes. In this way, they can monitor breathing in real time and detect problems immediately when they occur. With this information, you can predict anything from heart failure to opioid overdose.
Sleep apnea via mobile phone
It is a non-contact solution for detecting sleep apnea events on smartphones. The system monitors the tiny movements of the chest and abdomen caused by breathing. It can work when the phone is far away from the subject, and can simultaneously recognize and track the detailed breathing movements of multiple people. They do this by converting the phone into an active sonar system, which emits sound signals and listens to their reflections. The system monitors the smallest changes in these reflections to extract the movement of the chest and detect any changes or sudden changes.
Detection of opioid overdose
Another development has realized a system that can detect opioid overdose with just the phone. Nandakumar Wait. Turn a smartphone into a machine to detect changes in breathing before an opioid overdose.
After using sonar, the smartphone detected respiratory depression and apnea (temporary shortness of breath) in humans after using self-injection drugs. Clinically, respiratory changes were also detected during general anesthesia, which mimics the overdose caused by opioids.
Real-time detection of heart failure
This new artificial intelligence (AI) introduces short-range active sonar into the computer’s basic speaker, which can measure the heart rate and the interval between contactless beats.
These sensors measure your breathing rate and if there is interference, it will trigger an alarm.
Any smart speaker (such as Google Home and Amazon Alexa) can install software
At the University of Washington, they have studied how to effectively use these ubiquitous smart call devices, not just find our favorite music. They found a way to use them to bring health.
One of the goals is to monitor vital signs, such as breathing and heart rate, and use smart speakers to diagnose various medical conditions.
The key idea is to transform smart speakers into active sonar devices for non-contact wireless detection.
They will output sound signals from smart speakers. These signals are reflected in the human body and received by a series of microphones. When the human body moves (such as breathing exercise), these reflexes appear earlier or later, depending on whether the person inhales or exhales.
In this way, they will be able to extract information from human movements without contact. But not only when you leave the room. When you breathe in and breathe out, they can move like your chest to control the rhythm of breathing.
Active probes are naturally suitable for smart speakers because these devices have high-quality speakers, some of which (such as Apple HomePod and Amazon Echo) support a variety of 6-7 microphones, which are used for complex acoustic processing.
On the basis of this idea, they demonstrated in their previous work how to use this technology to monitor non-contact breathing movement on basic devices such as smartphones and speakers.
However, when the heart signal is weak and overwhelmed by the interference of breathing movement, it becomes challenging to extract a single heartbeat as an irregular heartbeat common in heart patients.
They evaluated the effectiveness of the system in healthy volunteers and heart patients with various structural and arrhythmia abnormalities, including atrial fibrillation, flutter, and congestive heart failure.
The results show that the smart speaker system can calculate average heart rate and heart rate variability with similar accuracy to electrocardiogram (ECG) sensors, and can identify patients with irregular heart rhythms (such as atrial fibrillation).
From there, if the situation looks really bad, Alexa will call 911 for you.
