Risks Of Hyperbaric Chambers: Central Nervous System Oxygen Toxicity - HBOT USA

[@christopherparsons4642]

I underwent about 60 HBOT sessions over about a 3 month period for tinnitus. I actually drove across the country to start my regimen at your clinic where I did 8 sessions. Most of my sessions were done at 2ata with a few done lower at 1.7. A handful of times I experienced what you termed middle ear syndrome when I described muffled and clogged ears post session usually the morning after. The rest of my treatments took place between two other facilities in hard chambers that administered 100% o2 to entire chamber, not like through the nasal cannulas used at your facility. The professionals (techs and Drs) at those facilities made it sound like I would benefit far more from this route of administration. Long story short my tinnitus became MUCH worse after my lengthy experience with hbot. I haven't been able to get a clear answer from any hbot professionals as to what could have caused this, but when I finally read into oxygen toxicity, free radical production, and tinnitus being a side effect, it was too late. I was floored that I could have been damaging myself and worsening my condition the entire time I was trying to treat it. Do you have any thoughts on this being a result of cumulative effects of O2 toxicity over that many sessions? I've been suffering with this question and a terrible new level of tinnitus for 6 months now post therapy without an appropriate response from any of my treatment sites.

Best thing for tinnitus is dry needling around the neck - sub occipital muscles. Will flare up but get better in time.

[@CL9k24a3]

Microdosing psilocybin mushrooms cured my that I got after radical chemotherapy as they are able to regenerate damaged nerves (to a point).

[@Kainkrup]

any change? It's worse or are you getting better?

Hi, I recently bought a home chamber. I’m an amateur masters weightlifter. The week I got the chamber I had already been training up to a peak week, all of which went great. Hitting some life time personal bests at 42… I had probably only started using the tank peak week… Normally we would have a deload or recovery week post heavy cycle. For me this week ended up being 6 weeks. I used the chamber every day. I had massive fatigue. With strength sports we talk about CNS fatigue a lot. This is how I felt. A 40% drop off of strength. Very little motivation. Disturbed sleep. Restless. Monkey mind while while trying to rest. This lasted about 3 weeks. The 4th week I got Covid. Weeks 1-3 of getting the tank I used it every day Week 4 not at all Week 5 post Covid i used in 4 times. I recovered pretty well Week 6 and from now on I use the chamber once a week. My strength is at about 80% again, but early on in this phase so that should rise. This is definitely something to be weary off for home users. My tank goes to 1.4ATA As the saying goes, too much of anything can be bad.

[@brockbickers]

So you think you got oxygen toxicity at 1.4at? I doubt it...

[@robertwood9984]

Competitive Weight Lifters are on different diets. Could that have contributed? Can O2 therapy trigger detox or Herzheimers?

[@Justin-ur5uc]

This could be a herxheimer reaction. Not saying it is, but it's possible you were experiencing parasite die-off without realizing you were dealing with it. I have Lyme and this would be my first thought if this happened to me, from prior experience using several different therapies, including ozone therapy. Something to think about! Hope you're doing well now

Great video. Thank you.

I’m undergoing 40 HBOT sessions for radiation wounds. Today I’m around 18 sessions in and I got Oxygen Toxicity. Very scary! It was at the end about 5 min before they wound start bringing me up. I did not alert the technician early on as I wasn’t sure what was going on. So needless to say my legs were jumpy, my chest was pumping hard, I couldn’t hear my self speak, I got nauseous and possibly dizzy but since I was laying down not sure. I thought I was having a heart attack! I’ve had no complications prior but ironically this was the first time I did not drink coffee prior to HBOT and the first time I did not have an empty stomach.

[@Kainkrup]

how are you now?

[@robertbuck7186]

? Can a soft chamber be adjusted or set up to be used to sleep in at normal atmospheric pressure just to avoid allergens in a house which are in the air? I am thinking of some Possibly type of way to supply clean breathable air into the chamber to sleep in at normal atmospheric pressure like by drawing it in from outside the house to where the compressors for the chamber are located? I know this sounds like a strange question to ask for a strange situation But there are reasons why such as allergic flare ups at night due to other people in the house washing hair, polishing nails, dusts being stirred up, pet odors from other rooms, lingering cooking smells, cleaning chemicals like laundry detergent and fabric softener etc. I have tried air purifiers but I am sensitive to the active carbon in most of the carbon filter air purifiers and can not sleep in a room or work in the area of any air purifier that has an active carbon component in the filter. The off gassing of new plastic materials and items troubles me as well. To other readers: Sorry for such a strange question but it may be a good way to make use of a soft chamber if one was purchased and used to get over a condition but the owner also wanted try to stop allergic flare ups due to other issues.

[@MarcMERLIN]

@HBOT USA: could you do a video that addresses the concerns of the effect on pressure on the eyes, between known and temporary short term effects and potential long term damage from a lot of exposure according to some sources?

[@calebreckerd]

What happens in the case of a diver if they experience 02 toxicity and they can’t be brought back to surface pressure because of the bends?

[@johns6984]

From Harch: In conclusion, oxygen toxicity at 1.5 and 1.75 ATA in chronic neurologically injured patients is a certainty. Acute toxicity seems to occur more frequently at 1.75 ATA than 1.5 ATA. Chronic oxygen toxicity occurs earlier in the treatment course at 1.75 ATA than 1.5 ATA and more frequently after prolonged uninterrupted courses of HBOT or escalation of pressure from 1.5 to 1.75 or 2.0 ATA. Finally, a third syndrome is described of an acute withdrawal effect from HBOT after prolonged courses at 1.75 ATA that responds to additional HBOT at lower pressures. All three of these syndromes may have long-term detrimental effects.

Any comments on this paper?

[@doctorinvizible2077]

Thanks for great info

[@quackidasial]

What's the treatment for oxygen toxicity? Time?

[@melih-kayar]

Hi! Do you suggest using cannula over an oxygen mask to reduce the CO2 intake in the dive session? Also, I have a 1.3 atm soft chamber at home and 95% Oxygen generator. I have a TBI, would it be helpful if I sleep in the chamber a couple times a week or it's still risky for the oxygen toxicity?

[@HBOTUSA]

Hi Melih, thanks for your question! It's hard to offer advice without knowing more specific information about you and your situation. Shoot an email to [e-mail] and we'd be happy to see how we can help you!

[@melih-kayar]

@@HBOTUSA just did. Thanks for your response!

[@katlegokotane3557]

After how sessions of soft hbo therapy would you say would start to build toxicity?

[@HBOTUSA]

Thanks for the question! Oxygen toxicity in a soft chamber would be extremely difficult to achieve. CNS oxygen toxicity of a scuba diver begins at a PO2 of about 1.4. In a hard chamber you're often around 2.0, and in a soft chamber you are likely closer to 1.27. Pulmonary oxygen toxicity begins at about 825 OTUs. In a soft chamber you get about 80 OTUs per hour.

[@jasond7699]

Great presentation. just one question; is the risk present just at the pressure or does time under pressure also influence this? So are the higher pressures safe depending on time spent at pressure, or the lower pressures create a risk after a certain amount of time?

[@HBOTUSA]

PO2 (the pressure of oxygen) is what influences CNS O2 Toxicity. Typically, a PO2 of 2.0 or greater is where the risk of oxygen toxicity begins to build. In a soft chamber at 1.3, the risks are astronomically low.

[@MotivationResolved]

Do you know of a “Blood Oxygen Saturation Monitor” that can read over 100%?

[@HBOTUSA]

No, because it's not possible to be over 100%. A pulse oximeter reads the saturation of your red blood cells, which cannot be saturated more than 100%. Hyperbaric oxygen therapy bypasses the red blood cell carrying capacity by dissolving oxygen directly into the plasma of the blood, which cannot be read by a pulse oximeter.
