Paul Beauchemin I watched a dozen videos from the live02 channel and still have no idea what the live02 machine does. Do you know what it does?

John Hemming Thats great, I still have no idea what the machine does.

Fred Cloud The main point of the device is to create hormesis - a stress on the body - in this case regarding Oxygen demand (exercise can create hormesis on the muscles)

LiveO2 device consists of an oxygen concentrator, a big bag and a mask. The concentrator fills the bag with 85-90% O2. You then put a mask on and breath the concentrated oxygen. For EWOT (exercise with oxygen training) you need a device like an exercise bike to use while breathing the concentrated O2.

LiveO2 also sells an upscale model that put 14% O2 in part of the bag. Then you can switch between hypoxia and hyperoxia during exercise.

Paul Beauchemin Thanks Paul for explaining. If it is the basic model then it is basically exercise with oxygen? I guess I was expecting something more elaborate than that. Maybe the switching back and forth between high and low oxygen is where the magic is. Its hard to tell in their videos which therapy the people are using as they discuss the game changing results.

How do you plan to use it?

Fred Cloud From what I gather the variation in oxygen levels is most important - even going from O2 rich to normal creates the effect (speculate that this is most of the effect from hyperbaric O2). I think  switching to the low O2 state probably pushes this to the next level. I assume its mostly elite athletes that wanted that feature as it mimics training at 10,000' elevation. Dropping back to sea level leaves the blood quite O2 enriched.

Paul Beauchemin Ok, now it is starting to make more sense, thank you for the deeper insight. btw, I know someone that uses a home hyperbaric with oxygen concentrator daily and says he loves it and on the surface it didnt make sense as a hyperbaric should concentrate the oxygen already, but now it makes a bit more sense. It is a home unit which are limited to 1.3 atmospheres I think and perhaps the extra oxygen mimics the higher atmosphere pro units.

Well let us know how you like your unit. I guess the only downside is that you have to exercise at home since you are tethered to the machine. I know you mentioned you like mountain biking at altitude, so I guess you are going to use this when you arent outdoors?

Fred Cloud I do like to mountain bike but it takes 2-3 hours out my day. This EWOT promises big results in a 15 minute session 3-5 times a week.

John Hemming I would conjecture that it has to do with partial pressure of CO2 created during exercise. Going from low O2 to high with high levels of CO2 in the blood may accelerate oxygenation of the blood.
