This is really great. For those who aren't familiar with what these machines can do, the calculation of an athlete's Vo2 max really isn't all that useful. However, a breakdown of the fat and carbohydrate calories burned at various efforts can be incredibly useful for helping an athlete learn how to fuel correctly for performance over distance. I'm not a physiologist or physician (and I'm sure what I'm about to say ma…

What are the devices you have in mind? It doesn't seem like the intersection between "people with biomedical engineering skills" and "people who need treatment limited by the expense of the equipment" would be that large. I suppose I can imagine a sort of shadow economy of cheap medical treatment on home-built equipment, but surely the providers would be uninsurable and sued into oblivion at the first mistake.
Ones that immediately comes to my mind are ultrasound,and hearing aids. If they were unregulated there would be cheap OTC devices available.
That being said I will haven't learned how to use it in a meaningful way myself. Getting a good image, and then interpreting the 2d video stream requires training!
Making ultrasound easy enough for non specialists to use will require an AI that guides the user and interprets the images. I'm not convinced skipping FDA approval would be a good idea in this case.
First comment on page. >My wife is an Ironman as well (Muskoka, Tremblant and Penticton). . She's been using Zwift since last year. Great way to train btw and great idea but. My concern would be a collapsed lung(s) if this wasn't calibrated correctly. To each their own, but stressing your lungs and diaphragm this much isn't a great idea. In a lab they can at least make sure you don't hurt yourself.
How would you get a collapsed lung from using this? And how does its calibration influence whether you get a collapsed lung? This device doesn't interfere with inspiration, and a large breath of air inflates your alveoli.

How could it cause one’s lungs to collapse? Isn’t the idea of measuring VO2 max that a tight seal is formed and all input and output is measured for O2 and CO2? It isn’t pressurizing or depressurizing.
But I doubt it is enough to draw a vacuum strong enough to break adhesion. Still, better safe than sorry, it would be good to read the instruction manual of a professional unit to see what kind of failure modes they have listed there.
Sometimes I wonder if the way to bypass the insane regulations around medical devices is to just publish them online for anyone to build themselves. Sure I won't have the minutes detail of million dollar medical equipment, but maybe I don't need all that precision, or maybe that's better than having no access at all to the measurements at all
We need a currently "missing" network effect that cheap 3d printer supporting everything from more flexible plastics to metal will eventually provide.
The title should be changed to reflect the title used in the article. "Accurate VO2 Max for Zwift and Strava" Especially considering the following: > Physiology labs that are normally used for testing VO2 max cost upwards of $60,000 and are certainly not portable. They have sensors that measure the same things only on a much finer level.
The person who wrote the article must've had a specific audience in mind, so they chose one title. The person who posted the article here must've had HN's audience in mind, so they chose a different title. Titles convey ultra-dense summary of the content, so there can be many titles appropriate for any given article. The purpose of the title is to attract _attention_ of the audience who the title-writer thinks would…
Regarding your post, I am curious if "Google" was removed by yourself(and later changed your mind) or the moderators?

Pulling a vacuum against your lung can break adhesion when done from the lung cavity.

I think this would really be great. The extra regulations of the FDA are showing to be more and more of a burden as years go on (let's not get into their corruption). Something like a chip and a device sold separately but trivially put together. I myself ran into this problem when trying to buy a blood lactate meter as an American, which can be trivially purchased all across Europe and Asia.

I work on a handheld ultrasound device that attached to a phone or a tablet. It is much easier to use than traditional ultrasound machines, because of the attention paid to the UX off the app, and the familiar smartphone UI. That being said I will haven't learned how to use it in a meaningful way myself. Getting a good image, and then interpreting the 2d video stream requires training! Making ultrasound easy enough f…
