Apple Executives Discuss Apple Watch's Life-Saving Health Features in New Interview

Following the introduction of the Apple Watch Series 10 and watchOS 11's new sleep apnea detection feature last month, Apple executives Jeff Williams, Dr. Sumbul Desai, and Jay Blahnik sat down for an interview with The Independent's David Phelan. The discussion is focused on the Apple Watch's health features.

Williams, who leads the Apple Watch engineering teams, said that Apple was inspired to add more health features to the Apple Watch after CEO Tim Cook received emails from customers who said the Apple Watch potentially saved their lives.

"So, we realized, wow, we have this opportunity – and even more, a responsibility," said Williams. "So, we began to look for opportunities. That's when we started pulling on threads and adding additional sensors and features like irregular rhythm, atrial fibrillation alerts, and all the way through to something like sleep apnea."

Williams added that his own sleep apnea diagnosis and subsequent usage of a CPAP machine to treat the condition provided him with "a new lease of life."

"It was less about pushing any personal agendas – we don't really do that at Apple – but it certainly helps to have experience in terms of being able to reinforce and encourage the team that there's such an opportunity to help people," said Williams. "Everybody in the team is just really inspired by this mission of trying to help people with their health."

Dr. Desai suggested that watchOS 11's new Vitals app that analyzes important health metrics during sleep could eventually work during the daytime too:

"If we could push, over time, to get that type of information during the day, well, we always pull on the thread to see what else we can do," she said.

Blahnik, who leads the teams behind Apple Fitness+ and other fitness technologies at Apple, emphasized the Apple Watch's utility for health and fitness.

"It's easy to forget, but 10 years ago, you didn't really know how far you were running unless you happened to have measured the distance in your car, say," he said. "GPS on the wrist was not a common thing. How measuring your activity adds up to something over your life and your longevity is a big deal."

Got to say, the vitals function has already came in handy. Wear my S9 to sleep every night and had an alert I saw on Wednesday morning -- as I was preparing to go to work -- saying my body temperature and respiration rate had been significantly out of normal range overnight. I felt a little funny with a bit of a stuffy nose and scratchy throat. Before I left, I decided to take a COVID test before going into the office just to rule that out.

... and that sucker came back positive faster than you could say hello. Later on Wednesday, I got knocked to my butt and I've been laid up the rest of the week. But it stopped me from exposing everyone in my office to COVID when my symptoms weren't bad enough for me to second guess what was going on or to stay home (aka when you are at your most infectious). It also let me start Paxlovid right at the onset of the illness, rather than well into it like the last time I had COVID. I fully attribute being able to start Paxlovid so early to why I am so much better today, two days later.

Its a small thing compared to what the watch can do but still no less important to me.

Good to get more usage out of existing sensors, but:
. Bring blood oxygen back
. Give us blood pressure (trends)
. give us blood glucose (trends)

Apple will not make the AW a medical device, that’s fine.

and lastly, start educating health professionals to actually look at th’e data users collect

Not much point in building it into the watch.
Actually there is a huge point and it would be a game changer for diabetics. I use one of the major CGM sensors (glucose sensor). They are great but have many downsides as well.

Most of all, they are not just skin contact. There is a little needle that goes into your body as well on each sensor. Also each sensor only lasts depending on the brand, for about 7-10 days max. Then you have to remove that sensor and "inject" a new one using the tool that comes with each sensor.
Each sensor is also expensive and insurance coverage is spotty depending on many factors.

So if Apple IS able to ever get even general glucose measurements from just the watch alone and no needle, it would still be useful. If they even could offer semi-close ballpark type numbers then a user could get a notification and then do a normal finger stick even to verify.

It would be a super big game changer! Live changing.

Surprised there is not a “drowning” feature, basically if your arm is still for a minute and it detected the watch is under 2.5ft of water and heart rate has stopped or is extremely rapid and no response to alerts that something serious is going on. :rolleyes:
It might not stop all drownings like in bathtubs when someone is intoxicated but possibly help people who have drowned in their pool and an alert goes out to your contacts immediately that are nearby, even your neighbor and all Apple devices sound an alert on a screen or speakers.

The Apple Watch is my favorite product they’ve made. I’m like a little data raccoon, always on the hunt for more metrics and new ways to interpret them. Excited to see how AI pattern detection might make the health insights even more valuable—the vitals tracking is a great addition imo.

But you are only guessing. While I have not used the Garmin I suspect there is a lot more going on in the AW. But Apple's model works for me.
When both watches use AMOLED displays, have GPS, music, optical heart rate sensors, they are not different animals. Same species.

Your Casio from 20 years ago is a different animal.
