@wjohnson100 yikes, that's horrible! we're learning how to do this in school, and, hopefully, we'll come out knowing how to do it better than the people who inserted yours...
A paramedic once told me you cant hold your breath for ever because your body will force its self into breathing. I ask you if thats true in your experience because you increase the time in what you do but allways end up taking breath and being ok. I saw another video of a young lad who had convultions by doing what you do and said he blacked out even thou i didnt see that on video. everybodys diffrent but you need to push ones self to get futher and as you do this your proberly best person2ask
I firstly thank you for your reply and still think what you do is amazing i have had a fast heart a few times because of anxitey and now like a nice low resting heart rate. even though what you do for 7 mins is not a rest in a sense i do belive it strengthens the body and could improve ones breathing and make the body less over active and thus making it more calm im 26 now so belive with some running and swimming and doing what you do with breath holding could improve my life in the long run.
What you do is amazing i could really use this in my life and have never done it before if you have the time could you contact me if you have facebook wwwblakey@hotmail.co.uk or email me on some advice on how to start and danger signs you may get from doing this i will look more on the net but will follow a pro by looking more into your videos as ive only seen a few. good luck !!! :) i also agree with the co meter as well as the co2 as its important to know both
@MrMcblakey I suppose there are dangers to this if you have heart problems. I got a big benefit to my resting heart rate (RHR) back in my late 30's when I did several marathons. After training several years, my RHR dropped drastically. It is now somewhere in the mid 40's, but as you have seen I can at will drop it down into the 30's for short periods of time. Also at the end of a long breath hold (6-7 minutes) my heart rate drops into the 30's.
@MrMcblakey There is nothing particularly special in what I do in this demonstration, just very slow shallow breathing, basically reducing breathing effort to a minimum and also reducing to a minimum the pressure of lung expansion on the heart (very shallow breathing). That's my theory anyway and I'm sticking to it. If memory serves, the lowest I have gone using these techniques is 32 bpm with no particularly special relaxation techniques that I am aware of.

Just want to say thanks for the preview on this oximeter. I'm a triathlete, rock climber, and aspiring alpinist; and I'm getting one for my girlfriend who is in school for respiratory therapy.
@ThunderMug2 You are welcome. If you have any questions please feel free to ask. Especially regarding the effects of hypoxia. I have experience all the way down to about 75% for short period.
The limit on a breath hold is the O2 level. At the end of a hold the effects of hypoxia are the reasons you get blackouts and sambas. There is no hour of O2.
not quite: The lungs also detect the CO2 level in the air. If you breathe in pure oxygen, you´d expect to be able to hold your breath at least 5 times as long as with normal air. However, I managed to hold my breath for only about twice as long when I did that experiment...
True but the atmospheric CO2 partial pressure is very low, compared to its partial pressure in the lungs, so breathing in pure O2 doesn's significantly affect the lung CO2 partial pressure, so you get an essentially normal buildup of CO2 in your lungs and blood during the hold after you breathed O2, which limited you hold to 2X.
Atomospheric CO2 about .04% whereas in the lungs it is equivalent to the amount of the O2 decrease during the hold, so if O2 drops from 21% to 17% then CO2 has to increase by the same amount to a total of 4.04%. The atmospheric CO2 is negligible as it relates to its effect on a breath hold.
for the last section 7:10 about holding breath for 6 minutes and still ox is 90%. From what i hear, a diver can oxidate their blood to the max, which would be enough for one hour of oxygen, but it is not the quantity of oxygen that hurts it is the presence of CO2 in the blood., this oximeter does not measure CO2, it needs CO-oximeter, which is new and very expensive still.. hopefully one day.
I use the oximeter to determine if my preparation is working to push the time out when the O2 level starts dropping precipitously. It is a gage of breathe up technique, relaxation technique, and O2 consumption. A very handy device.
No, I don't do measurements in or near the water. Only in dry settings.

So do you take your measurements before and after a free dive? From my understanding these devices aren't waterproof. Just curious.

I can only hold my breath for 20 seconds. What does this mean ?

how and what do you use it for prediving training?
how much delay time do you expect from in average? (minutes or hours), what was the brand? do you recommend it?

Not sure if I can do that. Too much O2 expenditure holding my arm up that long. Maybe I can figure a way to do it.
