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

The utility of hyperbaric oxygen remedy (HBOT) has superior method past decompression sickness (when scuba divers come to the floor too quickly). Amenities are arising all over the world, and so they’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 pressure 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 remedies, burns, and infections, and it may assist scale back the necessity for foot and leg amputations in diabetics. A physician will make a referral for these and different FDA-cleared circumstances, 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 performed for gender-affirming surgical procedure. Insurance coverage corporations together with Medicare will probably pay for all FDA-cleared remedies.
However what about different circumstances that persons are going to HBOT amenities for, like cognitive help and persistent Lyme illness? And what concerning the zip-up chambers for residence use? Is the expense and time price it? Medical HBOT is pricey until your medical health insurance covers it, to say nothing of being caught in a claustrophobia-inducing chamber for hours day by day along with your ears feeling the strain and with out your mobile phone for distraction. (Electronics are included in an extended checklist of issues that can not be introduced contained in the chambers.)
Hyperbaric Chambers: What It’s Like Inside
The remedy expertise varies amongst amenities. The John Muir Medical Middle in Walnut Creek, California, is an accredited facility that provides personal chambers manufactured 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 amenities, together with Legacy Emanuel Medical Middle in Portland and UCLA Hyperbaric Medication, have multioccupancy chambers that you could get up and transfer round in. You may learn a guide. They’re pressurized with air, and one hundred pc oxygen is delivered by way 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 folks discover the single-person chamber extra claustrophobic since you are bodily in a smaller house,” Huang says. “However different folks 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 3 occasions atmospheric strain at sea degree. To place this in perspective, two atmospheres of strain is what you’d expertise 33 toes deep within the ocean, and also you’d should go down 66 toes to see what three atmospheres looks like. Potential unintended effects embrace ear and sinus ache, a ruptured eardrum, and non permanent imaginative and prescient adjustments. Huang informed me that you just’re getting about 10 occasions extra oxygen than common when inhaling pure oxygen at two atmospheres of strain.
Evaluate this to the zip-up luggage you should purchase for private use that pressurize to just one.3 occasions atmospheric strain with common air. In keeping with Huang, these have been meant for the remedy of altitude illness, not for the various circumstances persons are utilizing them for now. “Some folks will take a bottle of oxygen into this mushy chamber and breathe pure oxygen from the bottle, which isn’t protected,” Huang says. “Oxygen is very flammable, and folks might 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 shortage of confirmed outcomes. Some sufferers determine to take issues additional and construct their very own hyperbaric chambers, which is clearly dangerous. He added, “I obtained 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 amenities 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 amenities across the San Francisco Bay Space to see what they stated about advantages for the extra controversial indications. I puzzled how their remedy plans would evaluate to research-based regimens for permitted indications. Based mostly on scientific analysis, remedy in an accredited facility sometimes entails 90 to 120 minutes each day, 5 days per week, for six weeks.
The amenities 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 employees ($250 to $450), who would decide a remedy plan for my numerous aches and pains. I would begin off with a common wellness routine of 90 minutes ($220 to $375 per session) at the very least twice per week, for a complete of 40 classes. It’s not stunning that amenities provide plans that don’t require each day attendance, despite the fact that it’s each day remedies which were studied clinically.
Off-Label Makes use of of HBOT
To search 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 might wish to attempt hyperbaric myself, and I’d additionally encourage a number of buddies with numerous points to take action.
In keeping with Ronald Gordon, MD, the CEO and founding father of eighth Aspect Hyperbaric Medication, persons 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’s not stunned by this. “If swelling is an enormous a part of what’s occurring, or there are muscle, ligament, or tendon strains or tears, then the reply is totally, hyperbaric would assist,” Gordon says. “Most, if not all, skilled athletic groups have their very own hyperbaric chambers.” Gordon explains that the rationale HBOT shouldn’t be 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 critically contemplating HBOT for indications together with lengthy COVID, concussions, and impaired cognition, and proper now within the US, 20 scientific trials are recruiting topics. Already scientific research have been revealed displaying the advantages of HBOT for restoration from strokes and mind accidents, even years after the harm. 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 shouldn’t be a thriller. Utilizing mind imaging, scientists have proven that HBOT results in an improve in cerebral blood move and extra exercise in mind areas that have been dormant. Kate Daly, MD, medical director on the All Factors North TMS and HBOT facilities, informed me that once they’ve used hyperbaric oxygen for concussion and postconcussive syndrome sufferers—lots of whom even have PTSD and despair—some sufferers report sudden advantages. “Folks typically 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 lowered blood move to the mind. The ensuing low oxygen ranges within the mind may very well be contributing to impairment—offering a rationale for HBOT. There’s a little analysis suggesting that HBOT could help wholesome cognition. In a single research on folks with Alzheimer’s illness, 40 minutes of HBOT for 20 days led to vital enhancements in cognition lasting at the very least 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 folks over age 64 resulted in improved scores for a number of measures of cognition, together with data processing. As is the case for many HBOT, remedy was intensive. Folks obtained 60 remedies at two atmospheres for 90 minutes, 5 days per week.
We don’t but know if less-intensive remedy regimens shall be useful, or if the advantages will outweigh the dangers below real-life circumstances in the long run. There may very well be oxygen toxicity with continued remedy for persistent circumstances, so longer and bigger research are wanted earlier than reaching conclusions. In keeping with Huang, one motive the large research required by the FDA haven’t but been performed is that pharmaceutical corporations can’t generate income from oxygen, so that they haven’t invested within the needed analysis.
There doesn’t seem like revealed proof supporting the usage of HBOT to deal with most cancers, Lyme illness, or autism spectrum dysfunction. I discovered minimal proof in help of its use for fibromyalgia or arthritis—just one scientific research 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: retaining pores and skin and tissue grafts alive. HBOT can be utilized to help therapeutic of tissue grafts utilized in gender-affirming surgical procedure.
HBOT in Gender-Affirming Surgical procedure
Simply south of San Francisco, eighth Aspect Hyperbaric Medication 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 Cellular Hyperbaric Facilities in Cleveland, Gordon knew that HBOT was essential for retaining grafts alive. Pores and skin grafts liable to tissue demise have lengthy been cleared for remedy with HBOT by the FDA and lined by insurance coverage. “As a practitioner, I used to be shocked that surgeons doing gender surgical procedure weren’t utilizing hyperbaric, that they have been accepting the extent of problems that they’d,” Gordon says. He based eighth Aspect to fill this hole. “Out of a pair hundred individuals who obtained 5 remedies or extra, we haven’t had anyone who didn’t get better. We’ll be publishing these information.”
Selecting an HBOT Facility
If you happen to determine to attempt hyperbaric oxygen remedy, right here’s what Huang informed me to search for. At a minimal, a health care provider may have accomplished a 40-hour course in hyperbaric medication. The gold customary is board certification in hyperbaric medication.
So far as amenities, the FDA would really like 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 educated.
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 lethal fires and explosions in unaccredited amenities. And oxygen oxidizes. Given all of the analysis on the dangerous results of oxidation and the advantages of antioxidants, you’d assume 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 sometimes as a result of the affected person has a head chilly. Different causes folks could not be capable to equalize ear strain are ear surgical procedures and infections.
Extra contraindications embrace claustrophobia, pneumothorax, and use of medicines similar to disulfiram, doxorubicin, and bleomycin. Potential contraindications could embrace persistent obstructive pulmonary illness, epidural ache pumps, and eye surgical procedures. As well as, excessive fever or epilepsy could make oxygen toxicity extra probably.
The Price of HBOT
Whether or not or not HBOT is roofed by insurance coverage is very variable. A prescription for remedy for one of many FDA-cleared circumstances at a hospital facility is prone to be lined. Remedy at a wellness middle for an off-label situation is much less of a positive 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 often has to speak to the physicians working for the insurance coverage corporations, telling them why they consider this remedy will assist the affected person and citing medical journals and different sources. “We have now been profitable, however that’s not at all times the case,” Rotella says. “In some instances, sufferers should 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 essential. Within the physique, oxygen is carried by hemoglobin, which requires iron with the intention to perform. Many ladies present signs of low iron and may profit from a complement. And an intensive wellness retreat will provide a wide range of circulation-boosting practices, together with loads of indulgence.
