Its a shame you crashed @mattm cus when you won nats I was going to post 'They should call it Matts'
Oh well, my bucket of creativity doesn't go much deeper than that.

Damn @mattm, heal up.
What does a rib fracture entail, prognosis-wise? Is it a major bummer wrt to time off the bike?

The idea - is get a pattern. Say you are normally 53-57 BPM in the AM. You wake up race day and you are 66. Unless its nerves, drugs or something you know about - don't race. You are not OK. It may take a day of rest, but you are not OK.
SpO2 - Internet search it but similar. This is the efficiency your blood is hanging on to O2. If you are fatter, live at higher altitude, or fighting something - it will be lower. If you have real thick skin it may be lower.
If you become acclimated to altitude (tent or real) it goes up. If you are near VO2 max its mid 80s. If you get low 80s your body is not supplying O2 to your organs and call a doctor. Mid 80s may affect your concentration and judgment.

SpO2 during efforts is an interesting thing, esp for power v position, but the problem is that o2 sat in your fingertips is not necessarily a great predictor of performance. other devices try to measure something similar but results vary highly depending on exactly where (on which muscle...generally cyclists are concerned with the legs) and how the device is placed.
i must say i've been a bit surprised to see the false positives of resting HR/AM HR, but ymmv/ykmmv.

it's pretty damn uncomfortable. coughing (or laughing) can be the worst....so no one get him sick or tell him any jokes, just to be safe.

The SP02 information is not quite correct. SP02 is the percentage of your red blood cells' hemoglobin that is bound to oxygen (ie your oxygen saturation). In the normal state, SP02 is equal to 5x FiO2. FiO2 is the fraction of inspired oxygen that you are breathing. Room air at low altitudes is approx 20% oxygen. Thus at low altitude, your SP02 is equal to about 100%. For practical purposes, an SP02 above 95% is means your hemoglobin is fully saturated. Ie everything is normal.
Pulse oximeters (the machines that measure SP02) are generally pretty inaccurate at SP02 values below 80%. This is not a fault of the machines, it has to do with the biochemistry of how hemoglobin interacts with oxygen. But really any SP02 reading below 95% in a person/animal breathing normal room air at low altitude is concerning. Below 90% is an indication for supplemental oxygen and suggests potentially really serious lung pathology like pneumonia or a pulmonary embolus.
Its true that being fatter or having thick skin can cause lower SP02 reading but this is only because it's hard for the machine to get a reading in those circumstances. It's also true that SP02 will be lower at high altitude, but this is only because the air at high altitude contains less oxygen, in the order of magnitude of 17% instead of 20%. Do the math to figure out SP02 at altitude.
If you are "fighting something," it will not affect your SP02 unless it's really bad as far as your lungs go. Not a cold or something minor. Major lung pathology.Sorry I don't really know what you are talking about or why it's thought a Pulse Oximeter would be useful to cycling training (other than its a super-easy way to measure HR). I just saw @mattm broke something and was reading back to find out what happened.
Heal up @mattm, sorry to hear about your crash. I hope you dont have enough lung pathology to affect your SP02.

@Heathpack dropping knowledge in the 33. I like it. You should spend more time here.

I flatted out today and had to take Uber Plus home after realizing my valve extenders didn't work with the spare tubes I had on me.

Ah balls, ribs suck. Don't heal slow. FWIW I found trainer work was more bearable than outdoors because you can find a fairly comfortable position and stick with it for the workout.

I'm heading to Fiesta Island to do a 20' FTP test. I'm feeling well and consistent enough to train again, great news.
This will be my first test in nearly 2 months due to my time off the bike/injuries/accident. I'm shooting for 290w, let's see what happens...

bummer to hear mattm, heal up quick.
shovelhd intervals today. felt decent once i got on the bike considering the lingering ksr fatigue but was super light headed when i first woke up...blamming the heat

Racing a MTB this evening, cause YOLO or something. Also cause I'm closing out this block and I'd so much rather race than do another frickin' interval set.
Yeah, sorry Doge, the SPO2 stuff you're talking about sounded a little pseudoscientific to me. Glad to see a more expert opinion on it.
The heart rate information is correct.
The SP02 information is not quite correct. SP02 is the percentage of your red blood cells' hemoglobin that is bound to oxygen (ie your oxygen saturation). In the normal state, SP02 is equal to 5x FiO2. FiO2 is the fraction of inspired oxygen that you are breathing. Room air at low altitudes is approx 20% oxygen.

Was only able to muster 280w (I'm always over ambitious)... Which puts me 20w (20!!!) below my FTP in early April. After 5min it was obvious by my HR and my PE that I wasn't going to hit my target, so I dialed it back 10w, and was still barely able to do it!
Turns out that taking 6 weeks off the bike is bad for your fitness, who knew?
Oh well, I'm happy to be healthy enough to train again. Rather than focusing on FTP improvement, I'm going to switch to AWC/Anaerobic recovery work, and see if I can salvage some points by the end of the season.

However, I suppose there could be some utility to measuring SP02 during a workout containing intervals that are meant to induce hypoxia. It would technically be difficult to do, though, its hard to get a good SP02 reading on a moving body. Not sure if that would be better than using a power target. It would probably be better than using a heart rate target, if an accurate measurement could be made.
