Hi dredger, using samozdrav in the hbot chamber is a good idea.
- The samoz's principle: you re-breathe the CO2 you exhale, so it acts by increasing the level of CO2 in the lungs and then in the blood. Once in the organs, CO2 helps O2 enter the cells. Co2 is the most powerful vasodilator, thus micronutrients and O2 enters more easily (this is why it's a good trick to take vitamins before going in the chamber).
This is the
Bohr effect, described over a century ago, and which you can read about in physiology textbooks: by increasing CO2 in your lungs thus in your blood, you increase O2 uptake.
- The hbot's principle: the pressure in the chamber forces O2 into the cells.
So, extra help for one, forcing for the other.
By combining the two, it's logical that the rate of O2 reaching the cell is even better.
If you're using a hyperbaric chamber of over 2.5 ata (those in hyperbaric medicine centers), there's no need for additional CO2, as the quantity of O2 entering the cell is already high whith such a pressure.
Conversely, a chamber that only goes up to 1.5 ata is not very effective. Adding CO2 will therefore increase the efficiency of this low-pressure chamber. I'm talking here only about adults, because in children, 1.5 ata is very effective, so there's no need to put them in chambers higher than 1.5.
You know about oxygen cylinders containing nearly 100% O2: in hospitals or at home for COPD patients who need oxygen for life. patients who need oxygen for life. Well, there are also
carbogen cylinders: 95% O2 and 5% CO2, or 93% / 7%. In comparison, ambient air contains only 0.03% CO2.
It was used in some hospitals, for inhalation inhaled (as with oxygen), to treat certain illnesses. Here is from wikipedia:
A carbogen mixture of 95% oxygen and 5%carbon dioxide can be used as part of the early treatment of central retinal artery occlusion. On this same premise it has also been proposed to be used in the management of sudden sensorineural hearing loss which can increase the blood flow to the inner ear and also possibly relieve the internal auditory artery spasm.
Its use in combinatio nwith nicotinamide is also being investigated in conjunction with radiation therapy in the treatment strategy of certain cancers. Because increased tumor oxygenation improves the cell-killing effects of radiation, it is thought that the inhalation of these agents during radiation therapy could increase its effectiveness.
Carbogen is also used in the manufacture of soft drinks (beer, sparkling water, champagne): "soda stream".
So, if you don't have carbogen in a large bottle fitted with a manometer sending both oxygen and carbon dioxide instead of your O2 extractor, you can indeed do samoz in the chamber, but do
several short sequences instead of a single 20-minute one, so that you
also have the O2 arriving in the chamber.
The oxymeter you show can indeed be interesting, even if you'd prefer getting a capnometer, as it reassures you about your good oxygenation.
To come back to using the samoz + mask and keep one's 2 hands free, i would be searching for such elastic headband, like the picture here :
... i'm currently using a normal (but big and thick) elastic, it's just a little bit uncomfortable but it's doing the job and i can consider doing more things while breathing in the samoz.
Try the Velcro brand fastening, or a large ribbon with an incision in the middle for the tube to pass through, and which you tie with a knot behind the head?
