Blasphemy!
prototype said:How do you make the co2?
Have a tank?
I wanna get one but kinda pricey here

I'm basing it on VoS's advice that 8% you are deep breathing needing to take in way more air. I havent' got to that poitnt yet, taking it easy.
Which minerals/how/do you have a source?Such_Saturation said:I hear carbon dioxide supplementation can deplete minerals.
Here, Wiki cites only to a non-authoritative advisory that I can see, which in turn cites to this, "Dripps RD, Comroe JH. The respiratory and circulatory response of normal man to inhalation of 7.6 and 10.4 percent CO, with a comparison of the maximal ventilation produced by severe muscular exercise, inhalation of CO, and maximum voluntary hyperventilation.

This seems like a safe enough way to experiment.aquaman said:tara said:If you have a mask strapped to your head, you don't want to pass out from too high a dose and not be awake enough to stop it. Bag breathing does not pose this risk, since you just drop the bag if you get too drowsy.
Yeah, i thought about this - i was just holding the mask to my face. But also I had no feeling of light headedness at all, definitely no headache etc.

I don't have access to this (1947?) study but I see that its results elsewhere seem to be summarized as "Aside from increased ventilation, the most common clinical symptom caused by CO2 breathing is a headache".
Here's a synopsis of recent findings about CO2 supplementation, now often called therapeutic or permissive hypercapnia:
Increasing clinical evidence supports the use of permissive
hypercapnia, particularly in acute lung injury/acute
respiratory distress syndrome, status asthmaticus, and
neonatal respiratory failure. However, there are no clinical
data examining the contribution of hypercapnia per se to
protective ventilatory strategies. Recent experimental
studies provide further support for the concept of
therapeutic hypercapnia, whereby deliberately elevated
PaCO2 may attenuate lung and systemic organ injury. CO2
administration attenuates experimental acute lung injury
because of adverse ventilatory strategies, mesenteric
ischemia reperfusion, and pulmonary endotoxin instillation.
Hypercapnic acidosis attenuates key effectors of the
inflammatory response and reduces lung neutrophil
infiltration. At the genomic level, hypercapnic acidosis
attenuates the activation of nuclear factor-kB, a key
regulator of the expression of multiple genes involved in the
inflammatory response. The physiologic effects of
hypercapnia, both beneficial and potentially deleterious, are
increasingly well understood. In addition, reports suggest
that humans can tolerate extreme levels of hypercapnia for
relatively prolonged periods without adverse effects.

I didn't know there was a question. What's the question you would ask? Maybe I could try to answer it from whatever research there is available?Blossom said:Maybe someone could email Dr. Peat and ask him what he thinks about breathing in CO2 directly from a tank in this manner? I know we have to think for ourselves but I'm afraid this might be a bit risky. The way I understand his work is that ideally we should in the long-term enhance CO2 through good thyroid function but in the short-term bag breathing can help. I know we all have to apply his work to our unique situation the way we see fit but I'd hate to see anyone accidentally go overboard. I love CO2 as much as the next person but I also respect the fact that it has the potential to stop breathing completely in excessive amounts applied too quickly. I mentioned the venturi mask because I think if one chooses to breathe in pure CO2 it can't hurt to be as precise as possible. I'm just curious as to what Peat himself might say on this topic.
