When Apple launched Apple Watch Series 4, President Ivor Benjamin, the American Heart Association president, said he was inspired by the "life-saving potential" of the device. A paramedic has now chimed in with a detailed look at how Apple Watch Series 4 wants and will not save lives. …
While most of the health policy was on the ECG function, paramedic Rich Mogull begins with case technology. He said that for older people, a fall can often be fatal.
I responded to countless "drop and fall" conversations over the years. This is one of the most common calls for paramedics. Especially for the elderly, the consequences of a fall can be fatal even when it's a quick response. Head injuries are frequent and severe, but hip fractures are even more common and can lead down a path from which it is very difficult to recover.
He discusses the limitations – cost, battery life and relative complexity of a demographic that can also fight for mental impairment "- but says that none of this changes a single fact:
At all, I'm incredibly excited about
Mogull says that Apple Watch is so good to detect AFib because it does not matter if the readings are not accurate. That's the pattern that means. To detect atrial fibrillation, the exact pulse rate is not important. Instead, Apple Watch looks at an irregular pulse and takes into account inherent noise due to the fact that the clock moves on the wrist or changes the light conditions. If it detects an irregularity pattern that matches AFib enough times, it warns that user.
The paramedic says that a key value of Watch is that it will alert users who otherwise would not be aware that they h is the condition – and can help avoid a blow.
Atrieflimmer is one of the most common heart problems, especially when we age, and a leading cause of stroke. Unless you go fast AFib (technical, AFib with fast ventricular response), you may not know that you ever have it. Early notification of asymptomatic AFib is an important deal, since it is a manageable condition. Far more manageable than a blow.
Interestingly, he says that ECG functionality is least likely to save a life, due to extremely limited capabilities for a single lead device.
A Lead In ECG, however, can not detect a heart attack [so detection] will always be limited to any known and large arrhythmias that are both detectable and effective.
But it does not make it worthless.
It will be of the greatest value for doctors to keep an eye on patients with known problems, especially since the optical AFib detection is more likely to find a previously undiagnosed presence of AFib […]
It may also be helpful to help patients with heart conditions register ECG during certain events and then share these ECGs with cardiologists – most cardiac events do not occur at the doctor's office.
Mogull does not see this as a big deal to address the risk of false positives. In particular, the fallout detection has plenty of security measures, and a paramedic would prefer to meet a conversation unnecessarily than not going on a real event.
I'm not worried that there are too many false positives. First, it's only on default if the user has identified as over 65 on the medical ID screen in the health program; otherwise you'll turn it on in the Watch app. Secondly, there is a subset of falling patterns that are quite clear and the combination of a fall, no movement for 1 minute, no response to an audible alert, and no response when 9-1-1 calls back should filter most of these outside. False positives are a fact of the job, and EMTs constantly distribute on defective fire alarms and harmless car accidents.
When owners in other countries will enjoy the benefits of ECG functionality, it is very unknown. It may take several years in Europe, but there is a chance that Apple took a concise approach that can see that it takes place much earlier than expected.
