Hyperbaric Oxygen Chambers: The Confirmed Advantages and Attainable Dangers
Written by: Gerda Endemann, PhD

The utility of hyperbaric oxygen remedy (HBOT) has superior means past decompression sickness (when scuba divers come to the floor too quickly). Amenities are arising all over the world, they usually’re getting used to deal with a variety of complaints, from surgical procedures that gained’t heal to fuzzy mind. You sit or lie in a pressurized chamber inhaling pure oxygen, and the excessive strain and excessive oxygen focus power further oxygen into the physique. This oxygen helps cells thrive and develop so tissues can restore themselves.
There’s good proof that HBOT helps heal tissues broken by most cancers radiation therapies, burns, and infections, and it might probably assist cut back the necessity for foot and leg amputations in diabetics. A health care provider will make a referral for these and other FDA-cleared conditions, together with extreme anemia and sudden imaginative and prescient or listening to loss. HBOT can be cleared by the FDA for the preservation of pores and skin grafts, together with these finished for gender-affirming surgical procedure. Insurance coverage firms together with Medicare will doubtless pay for all FDA-cleared therapies.
However what about different circumstances that individuals are going to HBOT services for, like cognitive assist and persistent Lyme illness? And what concerning the zip-up chambers for residence use? Is the expense and time value it? Medical HBOT is dear except your medical health insurance covers it, to say nothing of being caught in a claustrophobia-inducing chamber for hours on daily basis along with your ears feeling the strain and with out your cellular phone for distraction. (Electronics are included in a protracted checklist of issues that can’t be introduced contained in the chambers.)
Hyperbaric Chambers: What It’s Like Inside
The remedy expertise varies amongst services. The John Muir Medical Center in Walnut Creek, California, is an accredited facility that gives personal chambers fabricated from clear plastic so you’ll be able to watch TV. You lie down on a gurney and slide in and oxygen is pumped in at a excessive strain. Different accredited services, together with Legacy Emanuel Medical Center in Portland and UCLA Hyperbaric Medicine, have multioccupancy chambers which you can arise and transfer round in. You may learn a e-book. They’re pressurized with air, and one hundred pc oxygen is delivered by means of tight-fitting masks or hoods. I spoke with Enoch Huang, MD, medical director of the hyperbaric medication and wound care clinic at Legacy Emanuel, about these choices. “Some individuals discover the single-person chamber extra claustrophobic since you are bodily in a smaller area,” Huang says. “However different individuals discover it much less claustrophobic since you don’t have something so near your face.”
In a medical HBOT chamber, the strain is 2 to a few occasions atmospheric strain at sea degree. To place this in perspective, two atmospheres of strain is what you’d expertise 33 ft deep within the ocean, and also you’d need to go down 66 ft to see what three atmospheres appears like. Attainable unintended effects embody ear and sinus ache, a ruptured eardrum, and momentary imaginative and prescient adjustments. Huang informed me that you simply’re getting about 10 occasions extra oxygen than typical when inhaling pure oxygen at two atmospheres of strain.
Evaluate this to the zip-up baggage you should buy for private use that pressurize to only one.3 occasions atmospheric strain with common air. In line with Huang, these had been meant for the remedy of altitude illness, not for the various circumstances individuals are utilizing them for now. “Some individuals will take a bottle of oxygen into this tender chamber and breathe pure oxygen from the bottle, which isn’t protected,” Huang says. “Oxygen is extremely flammable, and people can be badly burned because of utilizing it in an unsafe method.” Huang notes that there are proponents of this sort of chamber to deal with autism, Lyme illness, a number of sclerosis, and cerebral palsy, however that it’s controversial due to the dearth of confirmed outcomes. Some sufferers resolve to take issues additional and construct their very own hyperbaric chambers, which is clearly dangerous. He added, “I acquired a name about an individual in Texas who constructed his personal hyperbaric chamber. It exploded and he had two collapsed lungs.”
Gaining Entry to Hyperbaric Chambers
Persons are constructing their very own chambers and going to services not related to hospitals as a result of with out one of many FDA- or Medicare-cleared circumstances, these are the one methods they’re able to entry HBOT.
I assumed I’d name just a few services across the San Francisco Bay Space to see what they stated about advantages for the extra controversial indications. I questioned how their remedy plans would evaluate to research-based regimens for authorised indications. Based mostly on scientific analysis, remedy in an accredited facility usually entails 90 to 120 minutes day by day, 5 days every week, for six weeks.
The services I spoke with confirmed that a health care provider’s prescription was required. If I didn’t have a prescription, I might see their doctor on workers ($250 to $450), who would decide a remedy plan for my varied aches and pains. I would begin off with a normal wellness routine of 90 minutes ($220 to $375 per session) a minimum of twice every week, for a complete of 40 periods. It’s not stunning that services supply plans that don’t require day by day attendance, regardless that it’s day by day therapies which have been studied clinically.
Off-Label Makes use of of HBOT
To seek out out extra about off-label makes use of of HBOT, I seemed into ongoing and revealed analysis and talked to practitioners. Spoiler alert: If it weren’t so costly and time-consuming, primarily based on this analysis I’d wish to strive hyperbaric myself, and I’d additionally encourage a number of buddies with varied points to take action.
In line with Ronald Gordon, MD, the CEO and founding father of 8th Element Hyperbaric Medicine, individuals are anecdotally reporting advantages from HBOT for sure off-label makes use of that aren’t but supported by analysis. Based mostly on the mechanisms by which HBOT works, he isn’t shocked by this. “If swelling is a giant a part of what’s occurring, or there are muscle, ligament, or tendon strains or tears, then the reply is completely, hyperbaric would assist,” Gordon says. “Most, if not all, skilled athletic groups have their very own hyperbaric chambers.” Gordon explains that the explanation HBOT just isn’t used on a regular basis for this type of harm is that it’s terribly costly.
The mind is a serious goal for off-label use of HBOT. Medical researchers are severely contemplating HBOT for indications together with lengthy COVID, concussions, and impaired cognition, and proper now within the US, 20 clinical trials are recruiting topics. Already scientific research have been revealed exhibiting the advantages of HBOT for restoration from strokes and brain injuries, even years after the injury. In veterans with treatment-resistant PTSD, HBOT has led to enhancements not solely in signs but in addition in mind construction and functioning.
How HBOT helps heal the mind just isn’t a thriller. Utilizing mind imaging, scientists have proven that HBOT results in an increase in cerebral blood flow and extra exercise in mind areas that had been dormant. Kate Daly, MD, medical director on the All Points North TMS and HBOT facilities, informed me that once they’ve used hyperbaric oxygen for concussion and postconcussive syndrome sufferers—a lot of whom even have PTSD and despair—some sufferers report surprising advantages. “Individuals usually say that their sleep is considerably improved, and lots of additionally discover an enchancment of their temper and nervousness,” Daly says.
Alzheimer’s and a few causes of impaired cognition are related to diminished blood move to the mind. The ensuing low oxygen ranges within the mind could possibly be contributing to impairment—offering a rationale for HBOT. There’s a little analysis suggesting that HBOT could assist wholesome cognition. In a single examine on individuals with Alzheimer’s illness, 40 minutes of HBOT for 20 days led to important improvements in cognition lasting a minimum of a month, enhancements that weren’t seen in untreated management sufferers. And cognitive advantages have been proven in wholesome adults. In a single trial, three months of HBOT for wholesome individuals over age 64 resulted in improved scores for a number of measures of cognition, together with info processing. As is the case for many HBOT, remedy was intensive. Individuals acquired 60 therapies at two atmospheres for 90 minutes, 5 days every week.
We don’t but know if less-intensive remedy regimens can be useful, or if the advantages will outweigh the dangers below real-life circumstances in the long run. There could possibly be oxygen toxicity with continued remedy for persistent circumstances, so longer and bigger research are wanted earlier than reaching conclusions. In line with Huang, one motive the massive research required by the FDA haven’t but been finished is that pharmaceutical firms can’t earn money from oxygen, in order that they haven’t invested within the obligatory analysis.
There doesn’t seem like revealed proof supporting using HBOT to deal with most cancers, Lyme disease, or autism spectrum disorder. I discovered minimal proof in assist of its use for fibromyalgia or arthritis—just one scientific examine every.
What I did discover is that HBOT is underutilized for one indication that has been accepted by the FDA, the Undersea and Hyperbaric Medical Society, and Medicare: maintaining pores and skin and tissue grafts alive. HBOT can be utilized to assist therapeutic of tissue grafts utilized in gender-affirming surgical procedure.
HBOT in Gender-Affirming Surgical procedure
Simply south of San Francisco, 8th Element Hyperbaric Medicine is devoted to supporting wholesome pores and skin and tissue grafts utilized in gender-affirming surgical procedure. These surgical procedures steadily fail when grafts die due to low blood move or an infection. From earlier expertise as founding father of Mobile Hyperbaric Centers in Cleveland, Gordon knew that HBOT was essential for maintaining grafts alive. Pores and skin grafts vulnerable to tissue dying have lengthy been cleared for remedy with HBOT by the FDA and coated by insurance coverage. “As a practitioner, I used to be surprised that surgeons doing gender surgical procedure weren’t utilizing hyperbaric, that they had been accepting the extent of issues that that they had,” Gordon says. He based eighth Component to fill this hole. “Out of a pair hundred individuals who acquired 5 therapies or extra, we haven’t had anyone who didn’t recuperate. We’ll be publishing these information.”
Selecting an HBOT Facility
When you resolve to strive hyperbaric oxygen remedy, right here’s what Huang informed me to search for. At a minimal, a health care provider could have accomplished a 40-hour course in hyperbaric medication. The gold customary is board certification in hyperbaric medication.
So far as services, the FDA would love you to make use of one which’s accredited by the Undersea and Hyperbaric Medical Society. This affords assurance that the chambers are constructed in response to code, the power has the suitable protocols in place, and the physicians are correctly skilled.
Bear in mind the Gray’s Anatomy episode the place a affected person lit a cigarette and his oxygen line exploded? Pure oxygen is harmful. There have been deadly fires and explosions in unaccredited services. And oxygen oxidizes. Given all of the analysis on the dangerous results of oxidation and the advantages of antioxidants, you’d suppose we’d wish to use pure oxygen solely when fairly sure of the long-term risk-to-benefit ratio.
Contraindications to Hyperbaric Oxygen
Jonathan Rotella, president and CEO of NexGen Hyperbaric, informed me that most individuals are capable of tolerate the strain. If they will’t, it’s usually as a result of the affected person has a head chilly. Different causes individuals could not be capable of equalize ear strain are ear surgical procedures and infections.
Further contraindications embody claustrophobia, pneumothorax, and use of medicines similar to disulfiram, doxorubicin, and bleomycin. Attainable contraindications could embody persistent obstructive pulmonary illness, epidural ache pumps, and eye surgical procedures. As well as, excessive fever or epilepsy could make oxygen toxicity extra doubtless.
The Price of HBOT
Whether or not or not HBOT is roofed by insurance coverage is extremely variable. A prescription for remedy for one of many FDA-cleared circumstances at a hospital facility is prone to be coated. Remedy at a wellness heart for an off-label situation is much less of a certain factor. At NexGen Hyperbaric, which makes use of HBOT for all kinds of circumstances, each on- and off-label, Rotella says they’ve been profitable in getting industrial insurance coverage to pay for concussions and despair. The doctor who prescribes the remedy normally has to speak to the physicians working for the insurance coverage firms, telling them why they imagine this remedy will assist the affected person and citing medical journals and different sources. “We now have been profitable, however that’s not at all times the case,” Rotella says. “In some instances, sufferers need to pay money.”
Associated Studying on goop
There are a number of approaches to assist get oxygen to the tissues that want it. Supporting good circulation of blood is vital. Within the physique, oxygen is carried by hemoglobin, which requires iron so as to operate. Many women show symptoms of low iron and can benefit from a supplement. And an intensive wellness retreat will supply quite a lot of circulation-boosting practices, together with loads of indulgence.
