Thank you for your inquiry.

The Vitaeris 320 is FDA cleared for 1.3ATA (4.26psi). We do have a new chamber capable of going to 7.5psi, however it is still awaiting FDA clearance and we cannot speculate on when it will be approved.

So there you have it from the manufacturer, the FDA-approved max pressure of the device is 4.26 psi above ambient. (~1.289 ATA at sea level, assuming max pressure is maintained).

I respect the fact that you are bringing detail and fact about the equipment to the discussion. But, specific to this particular study, what’s your take on the fact that the same plasma O2 concentration can be acheived with simple O2 therapy? (Never mind that hemoglobin is still carrying the Lion’s share of oxygen in a non-anemic patient).

Linking from the previous post on this subject, the Vitaeris320 does indeed have 2 pressure valves, but these can also be used to allow oxygen to be fed into the chamber. Some people use 100% oxygen from cylinders, others use portable oxygen concentrators that generate 90% oxygen from the air. Generally the oxygen is passed via tube, through this inlet, feeding either a mask or nasal cannula..

I predict pretty big hype on the horizon in the autism world for this pseudoHBOT. It seems that parents are often quick to pay for “hope”. I’m going to dig into the original paper that prompted my article much deeper in the near future. Thanks for reading and sharing your perspective about the past history with CP ‘treatment’.

Thank you as well for the kind words. You are welcome to contact me at comments at autismstreet daht org. No guarantees, but I try to answer most e-mail within a couple of days.

I would really like to get in touch with you. So please send an email to the adress I listed in the email field.
