I keep seeing these kind of posts about pulse oximetry in the new apple watch. If you are healthy and have normal physiology, you will have symptoms before your oxygen saturation shows below normal range. Please do not rely on machine to tell you when to seek medical help.

I have seen this answer. It ignores the fact there are plenty of people who had symptoms of low oxygen saturation and didn’t know why. Some just put it down to fatigue and don’t know they are infected with Covid or that their oxygen saturation is low. Your source is yourself (bad idea) instead of real victims. Here’s one of many people who discovered it too late. He fell into a 3 week coma after posting the below. If people have every tool possible on their person they can identify problems and get help faster. Maybe you haven’t read about it, but the Watch has saved lives in the past. So please don’t say people shouldn’t bother using “machines”.

Kind of strange you don't get ECG on the SE.
I don't think so. Of the features to leave off for cost savings, the ECG and O2 hardware make sense as they're more niche than general HR monitoring, which everyone(?) can benefit from. And I say this as someone who was indeed initially a little disappointed ECG wasn't part of the AW SE. Now, it does seem very sensible. I'd much rather have the compass and improved altimeter -- though those are preferences.
 
Physician here - what are you supposed to do with the blood oxygen monitor? Absolutely nothing (yet). It's a nice gimmick, but for most people this is a meaningless thing. If you climb or fly in unpressurized aircraft, this *could* be useful. Could because in mission critical situations if there's an issue you need to know the accuracy of the number and what to do with it. Most of us in healthcare know the limitations of the SpO2 and how to interpret it. Without that understanding I worry about people fixating on a number that's either inaccurate or meaningless. Furthermore, I have yet to see evidence of FDA 510K approval which is likely why they didn't make medical claims (e.g. it's for wellness & fitness).

I'm very interested to see this paired with the sleep features to see if home diagnosis of sleep apnea is possible. That would be a huge benefit if people actually wore their watches when they sleep (when would it charge? When I shower?)

Also could be useful in COPD/anyone on home oxygen.

We were worried about the EKG features but the data have shown plenty of patients benefiting from this and it seems like it's more accurate than previously thought.
Valid points. And as you probably know, self diagnosis is often a problem. But here's an important reminder about "Most of us in healthcare know the limitations of the SpO2 and how to interpret it." Exactly, and that's why Apple developed HealthKit.



As for "when would it charge? When I shower?"... Yes. And when you change clothes, eat a meal (at home), and more... Unless you feel you need to be attached to the Internet every moment of your life. :)

I'm getting a Watch 6 specifically for this reason. I don't have full-on apnea, but I'm pretty sure I have some airway obstruction that varies with my weight. (I may have had some level of apnea years back)

I'm most interested to see the O2 readings trend over time - I gained some weight recently and it seems like I might have crossed whatever threshold my body has for airway obstruction. The past year I was at a lower BMI and sleep breathing was good, seemingly. I plan to get back to that BMI and maybe the Watch can help me target where I need to be.

I know that what's most important is the variability of the SpO2 reading during sleep, and divergence from waking levels, rather than absolute numbers. Fitbit seems to have a good approach, they give the user a graph:

estimated-oxygen-variation-1-1579196259-1zfc-column-width-inline-1579872587-DvdC-column-width-...jpg


I'm never going to own a Fitibt and an Apple Watch, so I'm going to try to interpret the numbers this way, to give me clues about my breathing during sleep. I don't expect it to replicate a sleep clinic or anything, just to inform my guesses about what might be happening while I'm unconscious every night.
 
I simply don’t find the Series 6 a compelling upgrade for anyone with a Series 5 especially, because we have AoD and the current form factor, and even people with the Series 4. I think the Series 6 is less compelling to upgrade over the Series 5 than the Series 5 was over the Series 4. I think it’s a great upgrade for Series 3 and up users.
5GHz WLAN, “noticeable faster”, fast(er) charging, O2 measurement, brighter AOD, fresh battery, fresh warranty, U1 chip, W3 chip, more efficient CPU (= longer battery life when not using AOD), better sensors on the back, 50% louder speaker, new colors - not even sure that list is complete.

Don’t judge a book (only) by its cover - this year most of the improvements may be a bit hidden from the eye, but they are definitely there. Now, which of those really do apply to your personal use case or meet your personal criteria, is a totally different question.
 
I keep trying to justify getting rid of my SS Gold S4 and getting a S6. I'm trying...

Edit: I quit justifying and bought one for myself and one for my wife. That makes it fair, right?

Nice . Life is short, treat yourself! We’re you able to get a trade in on the old one?
 
Apple adds new watch faces, I get excited and then continue using Infograph Modular.



My nana always told me to frequently take advantage of my good health.

Modular is certainly a very popular one!
 
Does aluminum looks too cheap compare to the other models?

I always get aluminum with the sport band because it is much lighter weight and more comfortable to wear. I hardly even feel it on my wrist. I wear it all the time and like that it is easy to clean after workouts where you sweat. It is also more affordable which is good because I feel less guilty upgrading every year. I have the space gray case and I don't think it looks cheap at all. My first Apple Watch was SS and while the crystal was fine the case was scratched up which bothered me.

I definitely don’t disagree. I probably should have prefaced that post with ‘for me’ the Series 6 doesn’t represent a compelling upgrade from the Series 5. But if given the option to have my Series 5 or Series 6, well of course I’m going with the 6.

"but it's not really clear what we're supposed to do with blood oxygen levels."

I hope for some really cool Yoga breathing apps and breath holding trainer apnoe diving style apps coming :cool::cool::cool:

 
And no, it doesn't give peace of mind. Quite the opposite. There is a lot of articles or videos with professional doctors talking specifically about the ECG on the AWatch.

Can you provide some links to videos — thinking of getting a watch for the first time.
 
I didn't notice any speed improvement with the S5 after updating to OS7.
I have a Series 4 and I most definitely notice an improvement. Also, as smooth as AW animations have always been, they are even more so in watchOS 7. As a side note, I'm noticing an improvement even on my iPhone XS (iOS 14).

Decided to dive into the world of Apple Watches.

I initially was looking at the SE. But just before I was about to pull the trigger on it, I saw Apple Series 5 watches began to be offered on sale for $299. Well, found one of those at my local Walmart. So since the price difference wasn't *that* much between it and the SE, decided to make the purchase then and there.

Looking forward to trying it out. Just got the basic version (not cellular). Mainly go it for fitness and the ability to use Apple Pay with it. Like the concept of keeping my phone in my pocket and not having to get it out when I use Apple Pay. Also Fall Detection. Not getting any younger. And I live alone, so that does give me a bit of peace of mind.

Formerly had the 4, now 6, and I didn’t notice any speed improvements anywhere but in the way my watch processed Siri requests. That was much improved in 7 versus 6, but battery drain was horrible with the GM of 7. I’m sure they’ll fix it eventually.
As for ios14 I haven’t noticed any speed improvements on my 11 Pro. I have noticed battery drain in the GM that didn’t exist in the betas.

i find post like these are the source of misinformation. The person you mentioned had symptoms but he chose to ignore it.

Unless respiratory physiology and oxyHb dissociation curve has changed in the last 10 years, you can still have relatively normal oxygen saturation until your partial pressure of oxygen drops to about 8kPa/60mmHg. Now pO2 of 60mmHg is very low someone with no health issues.

The watch “may” be helpful in aiding your decision making when to seek help, however, one shouldn’t have to spend $400 to decide when to get help.

The only useful use of pulse oximetry with the watch that I can think of is for undiagnosed sleep apnea.

“I'm still on S2 and see no reason to upgrade.”

Cool.

“Initially I wanted for the ECG and O2 measurement but then when I researched it more those 2 are totally useless for me. I'm not in the risk category (60+) and overall its more marketing thing. Anyone interested with the topic, you can google doctors talking or measuring ECG and talking specifically how not useful it is at this point.”

Yeah, sure, you can google doctors saying it’s not helpful. You can also google doctors saying it is helpful. You can google doctors saying anything — they tend to have full vocabularies. I bet you can even google a doctor talking about how the ECG app was created by the deep state and thats why Epstein died, because he knew that there’s a kill switch, hidden in a underground bunker somewhere in Montana, and the government can use the ECG app to assassinate political enemies by causing their Apple Watch to deliver a high voltage surge that causes them to go into instant cardiac arrest.

The ECG app is aimed more towards afib — there have been numerous examples of an Apple Watch catching afib in a patient and potentially saving their lives. Those doctors should tell them how its only marketing, though, and not useful.

“Like ECG for example - Watch has only 1 measure point whereas any hospital has around 6-7 (or more).

No offense, but you’re quite misinformed about how the watch ECG works. For starters, the ECG isn’t one lead, it’s two. It forms a closed circuit between your finger on the crown and the the bottom of your wrist, so it gives a more accurate reading of your heart rate. I’ve been developing issues with tachycardia over the past few years, so I keep a log for my doctor, and we review it and make adjustments, from it as well as other data points. (or at least we did, before COVID shut down in-person VA appointments indefinitely).

Here’s an example: Last winter, I noticed my heart rate was spiking in the late afternoon, around the same time every day. I showed my doc the readings, she switched me to an extended release version of my blood pressure medicine, and it fixed the issue.

Yeah, it’s only two leads, but that’s two more leads than I had a year ago, and I like knowing that I’m in a nice sinus rhythm. Also, anytime I’m at the doctor — or, more specifically, when I was in the hospital for surgery this past March — I compared my watch ECG/heart rate to what they recording on their monitors, and there was virtually no difference.

“...Giving user false positive also creates issues not only for the person but also for the health care system so overall its not a reason to upgrade.”

*********. Show me the numbers. I want to see some real data, demonstrating how the Apple Watch having an ECG is creating a strain on the health care system. You made the assertion, back it up with some data. And what do you mean giving the user a “false positive”? A false positive what? Are you worried it’s going to say that you have a heart rate, when you really don’t, and that you’re actually dead?

“Those interested please research it as you will be amazed how much complex the issue truly is and not what Apple wants us to believe.”

You put your finger on the crown for 30 seconds while It measures your heart rhythm. Then it tells you what your average heart rate was, and if you were in a sinus rhythm. That‘s what it does. It’s pretty simple, and it doesn’t claim to do anything more complex.

I bet people said the same stuff when you became able to take your own temperature or take your own blood pressure. Hell, they probably said similar stuff when scales became affordable and you could weigh yourself.

I dunno, buddy. I guess don’t buy the watch if you don’t want to buy the watch. it’s your money, your choice. I bought it for a lot of reasons; the ones stated above, the fitness tracking, etc. But I mainly bought it because I‘m a nerd who likes gadgets and tech. It’s amazing what Apple has been able to cram into a freaking watch. Stop fighting the future and come ride the wave with us😎

***any typos or grammatical errors are the fault of my wiener dog, and not me.

What's with long written out passive-aggressive attack? The simple "it’s your money, your choice." comment would have been more than enough.

Can you turn off the "Always on"? Seems like a waste of the battery if you're wearing it while sitting at a desk all day or something? Sort of like having auto-lock turned on the phone. Who keeps their phone "always on" all day?

Goto Settings... Display & brightness.... Always on... On/off.
Battery life is better with AOD off.

The GPS SE 44mm iWatch is listed as $309 while the S5 version is $299 so it's relatively better to choose the S5 unless you want the new processor in the SE version though you get more additional features in the S5 over the SE.
Basically, the SE= S4 except for the former's chip upgrade.

Currently, Costco also has the S5 iWatches discounted to the same price but Target has not. Get them while it's available if one is considering the SE. The S5 is still a good value especially when it's on sale.

Ok. Apple removed the charger for "environmental" reasons. Surely the retail price was decreased accordingly. Was it?
