A smartwatch designed to detect the risk of a cardiac arrest and issue a call to emergency services is no longer a concept, but a reality. Unlike regular smartwatches that have tracking and motion sensors, this device is equipped with state-of-the-art AI technology that has a 99.99% accuracy in detecting cardiac arrest. In addition, the smartwatch can take care of emergencies by contacting the nearest hospital or clinic once the condition is confirmed.
This device is controlled by machine learning algorithms and is able to assess for signs of heart attack through advanced photoplethysmography (PPG) cardio mimesis. The smartwatch regularly checks the heart of the user. If it is beating too low or stops entirely, the smartwatch will perform an analysis of the user's state for 57 seconds. If no movement is detected, the user will be assumed to be unresponsive, resulting in the smartwatch calling the clinic on the user's behalf.
This device can work with accuracy both in real-life scenarios and clinical settings. The capabilities of a smartwatch have evolved to the next level. Obtaining a device that can potentially save your life is now on a smartwatch rather than on a phone or a device meant for emergencies. This breakthrough is relatively new and it is speculated that the day is not far when advanced technology becomes widely accessible.
How was the study carried out in this study?
To conduct this study, a total of 100 patients were placed in a very controlled electrophysiology lab setting, where their heart was deliberately stopped. In addition, there was a condition of pulselessness (which is heart beat cessation) which was inflicted on 99 other subjects by tourniquet-induced vein blockage. In parallel, 948 individuals tried the smartwatch during their daily activities. Additionally, 21 stuntmen simulated a sudden fall event, so that the cardiac arrest could be acted out realistically in the field.
The study would serve to prove how effective a smartwatch is.
As per the study, the ability to detect heart attack increased from 72 percent to 100 percent in a completely sedentary individual, but in cases of attempts at sudden standing it dropped to 53 percent. The study also determined that falsified emergency calls from smartwatches do exist, but the frequency is quite low (one false call per 21.67 user years) which means the probability of such calls is highly unlikely.
There is no doubt these findings will benefit clinicians treating cardiac patients.
Professionals recommend this smartwatch because it has the potential to be life-saving by detecting heart rate pauses at critical moments. This could be particularly useful for situations where no one is around to help. Scientists keep working on these devices to make them more precise and dependable.
