Do you guys ever check your O2 saturation levels?

Between that and your career you're lucky to be alive!

I prefer blessed, but I concur.

For the last 30 days or so. My daily average was 93.6 to 96.5%
The latest at 6:53 AM was 98%
The chart is from my Apple Watch. Being it is constantly monitored, like anything there could be a momentary unsustained blip lower or upper I guess. Each line is per day for 30 days.

( I have had my O2 level checked at least a dozen times in a medical facility 2025 but never thought to ask, yet no one ever said anything negative either. )

PS my EF has been checked up to about 6 (or more?) times times over the last 7 years or so. Once by a cardiac angiogram and others by nuclear stress tests & cardiac echograms.
I run from 55 to 60. Highest ever was 70 and I got concerned.
What is wrong in the OP is he does not list the range. Sure 70 is ok, so is 52.
Your doctor who runs the test will advise you.

The chart from my Apple Watch show me pretty much in that range. Being it is constantly monitored, like anything there could be a momentary unsustained blip lower or upper.

Interesting. That's a wide range. Did that 89% occur while you were sleeping?

At the time it was, the more the better. That’s not the thinking today because they’re finding that Boomers burned themselves up doing this stuff.

I do not have the heart issues like you do but I over did it with a jogging obsession in the late 70s thru the 90s. I am paying for the damage it did to my knees, hips, low back and ankles these days because most of the heavy jogging was done on concrete paths or streets. I used to check the O2 levels recently and it was in the 92-96 ranges. I had to stop all of that physical stuff years back when I had spinal fusions and back issues from neck to tail bones. I just recently began trying to stick with a daily walking routine again after years of being idle. Taking it really slow and short to begin this time.

Looking day by day it seems that way. It constantly monitors while you sleep and during the daytime way less and more random. Maybe just during workouts daytime... I never much examined it, except to know the graph I presented it seems is literally 80% sleeping. It's constant during that time like a couple times an hour. I ALSO UPDATED my post #22 with EF comments. The watch looks for sleep apnea but not sure if that is O2 or respiration rate which it also monitors while you sleep. Never focused on this stuff vs heart.

Props to you for starting a walking program. Exercise is good for the mind as well. I'm a Type A personality with a mind that seldom rests. I get bored on vacations! The ONLY time in my life that I enjoy a total Zen is when I'm on my bike. Be mindful and train yourself to go full Zen on your walks. It can be a real luxury.

You backed it up with data from the Cleveland Clinic, but their EF numbers look low to me. Also too, does a person's EF vary by a wide margin? I've been told it doesn't.

With respect to the 89% O2 sat while sleeping, maybe you should investigate a CPAP machine...? Yeah, I know, they're the sexiest thing in the world.

I may buy a new Apple Watch to get realtime O2 sat levels. My watch doesn't have that capability.

Thanks for your feedback.

At home, regardless of heart rate, exercise, eating, etc.....98-99%. Last time at the doc, 100%. Never saw that before.

 

[alarmguy]

@slo town
EDIT - Correction, My heart rate routinely drops into the 40s and low 50s while sleeping.

This was last nights heart rate. Didnt sleep well, have a stressful non health issue this week.

This is a full year heart rate. Typically I drop into the 40s and low 50s. I tapped on one month to bring scale to the chart. You can see all the low 40 lines for every month. Those are while I sleep .

Those are fantastic numbers for an older guy. I'm envious!

I envy your BMI. At my peak my BMI was never lower than 25. It's 30 now because I've fattened up and have gotten an inch shorter, but my "clydesdale" physique will always keep my BMI on the higher side. For a clydesdale I was known to be an exceptional

I had MANY a clydesdale, and kids, and old folks pass me while training/racing. I was middle of the pac but determined (not real smart)

Gosh I am slow to edit and you guys fast to read. I updated my #29 post.

Determination is good, but less so when it becomes "grim determination".

There were many times I was absolutely miserable on the saddle and I questioned why I did these things. One time in a 200 mile event in the SoCal desert I was so blown I could barely get myself rolling from stop signs and traffic lights near the end. Those were the longest 5 miles of my life. I was so nauseous from lactic acidosis I couldn't eat anything until the next morning.

It's just a number +/- 2-3-4?? I doubt 96% v. 100% makes much of a difference day in and day out IMHO

To me, it's all about visceral fat and toxins.

Its more than "determination and/or goal setting", one must have a "vision".
Original organizer/owner of the Leadville Race Series & Hall Of Fame inductee Ken Chlouber ( https://leadvillesportshall.com/ken-chlouber/ ) always gives a motivation speech before the Leadville races saying, " your capable of more than you think you are". He is so right

I am 67 and just had my annual checkup and mine was 99%..via the finger clip onmy fitbit says around 95% most days...I am in decent shape with a history much like the OP.. was a competitive cyclist best double century was 10 hours. did tri's and have have run 9 marathons fastest 2:48 slowest was boston 3:05 on the clock but corrected time was ~2:57 or something like that. I trained to do a 5 hour century last year and came close but no banana...maybe this year I will get it done...I am considered obese but can bike and hike pretty decent for a fat guy...I am going to drop a bit of weight and see if that helps...a buddy and I do a 16 mile hike weekly at a good clip. unfortunately my buddy has a knee surgery in a week so that kind puts a halt to my fast hikes because not many old guys what to hoof it like he does and not something I will do solo that fast.

I'm not sure I had any "vision", it's just that I felt compelled to compete in these kinds of things. I like doing things that most people either can't or won't.

My wonderful wife Sue used to ask me, "What are you trying to run from when you do this stuff?". I still don't have an answer other than it was a way for me to escape into my own private world.

Assuming you are talking total time, not just riding time, you are freaking fast! Wow!

I don't check my own, but my family members have asthma so very familiar with this.
My mom recently had her heart valve replaced. Just before that, her O2 was in the high 80s (very bad) when she landed in the hospital.
She is back to normal with a new valve thankfully at 88 years young.

Jim Fixx wrote, "The Complete Book Of Running"...... He dropped dead at 52.

Jim Fixx, the author who popularized jogging, died from a heart attack at age 52 on July 20, 1984, while on a run in Vermont, ironically after promoting exercise as a cure for heart disease, though his autopsy revealed severe blocked arteries and a family history of heart issues.
