UPDATE 4/6/20: A pilot study on HBOT for COVID-19 is starting in New York.
Chen and colleagues have reported the results of 5 patients with severe to moderate Adult Respiratory Distress Syndrome (ARDS) treated with hyperbaric oxygen therapy (HBOT). Patients received a mean of 4.6 HBOT treatments in addition to usual care. Symptoms of hypoxia improved with the first treatment, and oxygen saturation significantly increased (P<0.01). Mean daily oxygen saturation improved to >95% over the treatment course. After HBOT, PaO2 and SaO2 were significantly increased (P<0.05) and Chest CT showed significant improvement in the appearance of the lungs. I’ve been getting calls and emails asking what I thought about this, so I asked Dr. Sandra Wainwright to guest blog her informal thoughts through the lens of a critical care/hyperbaric medicine physician.

Late night thoughts on HBOT for Critically Ill patients with COVID-19 pneumonia
I am a Critical Care physician trained in Hyperbaric Medicine. Sadly, my ICU is currently full of critically ill patients with COVID-19 pneumonia, most of them intubated. My colleagues and I have been caring for them for several days, so I have some insight into the issue of critically ill patients with COVID-19 Pneumonia. In COVID-19 pneumonia, the lungs are not able to allow oxygen to diffuse to the bloodstream. I have read the article by Chen and colleagues. At least one hope is that the significant elevation in inspired oxygen during HBOT would enable oxygen to reach the arterioles even though the air sacs of the alveoli are damaged.
These are my thoughts off the top of my head. Please do not take anything I say as the opinion of anyone other than me, and my opinion might change. But, since you asked…
While treating these very sick patients, I had been mulling over the idea of using HBOT for COVID-19 pneumonia but disregarded it, at least for OUR Monoplace because we’re not set up to do critical care HBOT. There are some hyperbaric facilities where Monoplace chambers are used to provide excellent critical care. However, if a facility is not experienced with HBOT in critically ill patients, I would not want to learn on a COVID-19 patient. Another obvious consideration is the infection control issue, including potential staff exposure. The chamber would require a terminal clean after each treatment. The virus apparently can live for quite a while on certain surfaces. Conceptually, HBOT for COVID-19 pneumonia patients makes more sense (to me) with a Mulitplace chamber, although there are fewer of those facilities. The whole issue of facility capability (staff and equipment) is complex. The key is always to know your limitations. I don’t think many facilities would be able to do this.
If you ask what I think insofar as the physiological rationale, I think HBOT is a viable option for COVID-19 hypoxia. I am unsure whether it is a PRACTICAL option. We are finding that a cytokine storm occurs around “day 7” of infection. About 6-10 days into the illness, this storm and its consequences can be quite severe. This cytokine storm can lead to severe Adult Respiratory Distress Syndrome (ARDS) and profound hypoxemia. Usually not many other organ systems are affected though we’re seeing some renal failure partly from hypotension. Hypotension affecting the kidneys may be due to the very high Positive End Expiratory Pressures (PEEP) required combined with underlying Chronic Kidney Disease, exacerbated by hypoxemia. With regard to staff COVID-19 exposure, I feel a bit safer in the ICU with patients who are on ventilators (that have an n95 filter) than with patients who are coughing into the room. Naturally we clinicians wear n95 masks and protective gear. My point is that we have to consider the way in which the patient’s current breathing system might or might not pose a threat to the caregivers.
There are COVID-19 pneumonia patients who just “hang out” on Non Re-breather (NRB) face mask oxygen for several days. Some of them get better and some worsen and require intubation. If we can avoid intubation, their length of stay in the ICU appears to be shortened somewhat. For complex reasons, lying prone (face down) improves arterial oxygen levels so we recommend patients “prone” themselves at night on NRB by simply lying on their stomach. Also early mobilization is helpful. However, once a patient is intubated, they clearly cannot mobilize themselves. Once intubated, the best way to improve oxygenation is to keep them lying face down, or provide extracorporeal membrane oxygenation (ECMO).
Thus, HBOT may be an option for very sick but not yet intubated patients as way to keep intubation from becoming necessary. There may be a subset of patients who are on, for example 6 liters of nasal canula oxygen or on 100% NRB, and are still hypoxic. Those are the patients likely headed for intubation. If they were given HBOT via the Built in Breathing (BIBS) (which also has the advantage of protecting inside attendants from their respiratory particles), HBOT may be able to adequately oxygenate the blood and delay or prevent the need for intubation.
Right now all the intubated patients in ARDS from COVID-19 are being “bridged” with the ventilator. Meaning, we are trying to buy time, allowing them to survive the protracted hypoxemia and lung injury until some healing can occur. Intubated patients will be on the vent for about 2 weeks. It is possible that HBOT could be a “bridge” to get patients past the need for intubation. We also believe that HBOT will have an additive anti-inflammatory effect.
The paper reports only a small number of patients, so we have to be careful drawing conclusions. The risk of HBOT is generally low, although somewhat higher in sick patients. If it prevents intubation, it would be worth it. At least, that’s how I would feel if I were the patient, something which frankly, is possible.
There are a lot of considerations I am not properly addressing such at the issue of respiratory arrest while the patient is in the chamber and the challenge of responding to that. I have been asked about taking already intubated patients from the ICU to undergo HBOT. I have to say that keeping them oxygenated has required all of the skill we have and all of the capabilities of our ICU ventilators. Patients have to be removed from that environment to get to HBOT, and their respiratory support during the transport is not as good as it is in the unit, to say nothing of the ventilator capability in the chamber. We want to “first do no harm.” Thus, I would not recommend moving a critically ill patient with COVID-19 pneumonia so that they can undergo HBOT when the transport itself is risky. It makes far better sense to me to use HBOT (if possible) to try to prevent intubation, but this would have to be done very thoughtfully and the mere availability of a chamber is not sufficient. The entire HBOT team would have to be skilled at handling very sick patients and it would require careful coordination. For these reasons and others, I do not see adjunctive HBOT as a commonly available option. However, if there is one good that is coming out of this crisis, it is the speed with which innovation is occurring when everyone works together. If we can overcome barriers so that patients are not exposed to the risk of HARM in order to give HBOT a try, then in places where it can be performed safely, it may be a treatment option – with a LOT of caveats.

What are the relative risks of complications such as pneumothorax in viral pneumonia patients?
Innate immunity (monocytes and natural killer cells) are key to defeating viral infections. Any evidence of HBOT to improve innate immunity?
I would like to see monocytes levels at baseline and daily (from a research point of view).
Any thoughts fellow clinicians?
Hi Wade,
I have here some documents in regards to HBOT and COvId 19, maybe you guys and Dr C or whoever can help look into this as well.
https://clinicaltrials.gov/ct2/show/NCT04332081
My felling was to use in multiplace chambers which I know are limited but like Dr Fife has and use prior to intubation and see if it improves and lowers viral load as Dr Farrow is alluding to.
Use pressurize military planes easily converted to multi chanbers.
Yes that’s what I was thinking easy to sanitize as well & precaution for staff to wear all over clothing that’s of no risk treating more people than one at a time..hugs to great minds think alike..

I am very happy with the experimental protocols in place in the US (San Diego and NY) and I hope the efficacy of HBOT in patients with severe COVID-19 pneumonia will be pointed out.
In Italy, we are awaiting authorization from the Ethics Committee for a pilot study involving five HBO sessions in positive patients asymptomatic or with initial symptoms to check if the rhinopharyngeal swab becomes negative. The scientific rationale is based on the notion that Nitric Oxide and ROS block the virus. In addition, ROS up-regulate the expression of the Hypoxia Inducible Factor (HIF) which, through catalecidines such as CRAMP and defensins, makes the virus harmless. As an Italian, I am proud that the protocol is supported by all the stakeholders (and by a Spanish partner) united by the willness to overcome this difficult emergency together. The information will be shared with the US community. Kind regards, Pasquale Longobardi (Medical Director Hyperbaric Centre in Ravenna, President of the Italian Diving and Hyperbaric Medical Society – https://simsi.it/)
okay, how much pressure do you need to make a difference? There is more oxygen in a high pressure environment. So the lungs will get more O2 with each breath.
If you could pressurize the who ward to 1.75 atmospheres would that make a difference?
If you could get everyone treated in that kind of enhanced pressure, could we keep some off ventilators, because those who are vented often die. If higher pressure will save lives do you think a whole ward pressurized to that degree will improve things?
If so we can do this. Thousands are dying.
And we can create wards with that kind of enhanced pressure.
Every wide body jet could be a treatment ward. The pressurization system can bring them to that on the ground. Would not even need to run the engines. Just the app.
If this can work then we need to do it
not easy(
I tried to talk to Airline companies in US and in Russia they are absolutely willing and ready to do that but NIH certification is required and certification from airplane producers is required(
Steve,
The same thought ocurred to me yesterday, so I posted this on LinkedIn: https://www.linkedin.com/posts/gwmarek_covid19-ventilator-respiration-activity-6656357158206128129-TMiO Then I found your post just now. Intuitively, it seems like it could help at modest pressures over longer times.
Great idea. Every wide body jet should be able to support 1.75 bars of oxygen at least. These planes are not flying and they could be incredibly good therapy for the majority of critical care patients who need higher oxygenation levels. It is oxygen failure and not respiratory failure that we need to treat in the majority of cases.
Wuhan experience of Zhong Nanshan suggests 1.6 ATA needed, over 2 hours/day for about a week …Dr. Fife certainly the expert here, but directions on how the Chinese Naval HBOT provided by the Chinese Naval Specialty Medical Center Program Team paper …hope this helps
I am in NY and shortly after starting to have symptoms of covid-19, I started mild hyperbaric oxygen therapy via a soft home chamber, with an attached oxygen concentrator that was providing 100% oxygen that I breathed through a mask during each dive. I had previously used this setup to treat a recalcitrant case of lyme disease. The pressure in the chamber reaches 1.3 atm. I was able to get tested for covid-19 on day 9 of my symptoms and the test came back negative. My flu test was also negative. I had all symptoms of covid – fatigue, dry cough, shortness of breath, muscle pain, GI symptoms, loss of smell, etc. I definitely felt the hbot treatments helped. Perhaps they made my test negative as well. Awaiting antibody testing to confirm I had it. After two weeks of illness, I now feel well.
Mary Beth,
I am so happy I came across your post while researching mHBOT for Covid19.
I am glad you are doing better. It is great to hear you again treated yourself successfully with a home chamber! You are the first I know of that has done this for Covid19, and I am not surprised it worked.
I have thought of you often. Thank you for posting your success.
“Phoiph”
Thank you for posting. I, too, have an mbot unit at home. It helps with joint pain and other symptoms I suffer from. I’m curious if your antibody test came back yet? If you can post an update, it would be great. Thanks and be well.
I would love to read an update ease Mary Beth
Mary Beth I am a veterinarian and board certified veterinary surgeon and critical care specialist with a wife who has multiple myeloma .She has had 299 treatments with a soft HB chamber. I used duct tape to get the pressure in the chamber to near 5 PSI and I also use an oxygen concentrator and NR facemask when she gets an hour to 1.5 hour treatment. I would appreciate your feed back on whether you would consider the continued use of the chamber to help prevent COVID infection. Of course when we are out of our home we are wearing an N95 mask and a surgical mask over that and being very careful with hand washing, etc., So appreciate your input. Also a last question: Do you think the COVID 19 test you got might have given you a false negative result for various reasons (poor sampling technique, low viral load, etc.). D Tim Crowe, DVM, 706-296-7020
Thank you for sharing!
My Mom tested positive for Covid and I too have a soft chamber and was planning to put her in . How long did you stay in and how did you administer the O2? I have 10 liter Concentrator… I have heard it was not recommended to use O2 tanks.
Have you looked into Trans-sodium crocetinate (TSC)
My question, as a hyperbaric technician using mono place chambers only, does the treatment aerosolize(sp?) the virus? So when staff opens the door after a treatment, would the virus be in the air coming out and therefore in the room? Would it be possible to infect the other patients coming in or out for hyperbarics if in same room?
If the patient is infected, they typically shed very large amounts of virus. This starts some time between infection and onset of symptoms (onset is average of 5 days) and continues often for 10-14 days after symptoms start. There are outliers who would shed shorter or longer periods.
Even without coughing, tons of viral particles could be shed into the room.
Of course, asymptomatic infections likewise may shed virus for days / weeks, and yet never develop clinical symptoms or have extremely mild symptoms.
Dr Farrow
Thank you!
If using an airplane, the pressures can be equalized at the end of treatment or even turned into a negative pressure for staff to come and go. This is an interesting theoretical approach to this crazy disease. Using this treatment for acutely ill, but not ICU-on-death’s-actual-door-ill patients would be great, as a ward nursing system could be designed in planes and then only if patients went sour would they need transport to a ‘real’ hospital. This would take volume away from overburdened hospitals, and could facilitate more rapid recovery for patients. Of course the ‘going sour’ patients would present a whole other problem as I understand these Covid patients can go downhill rapidly.
This is an interesting article that just came out on medscape: https://www.medscape.com/viewarticle/928236?nlid=134913_3901&src=wnl_newsalrt_200406_MSCPEDIT&uac=40418EN&impID=2337551&faf=1#vp_2
Perhaps the suggested protocol would help guide potential HBOT usage.
I’ve also heard from a professor friend now that cpap units are being brought to bear where ventilators are short. Perhaps they too would merit incorporation into any protocols?
I understand that the UK ( according to Dr.John Campbell of England) has recruited Formula One engineers to design a CPAP machine that is cheap, portable etc and they are, as I understand it, shortly, if not now, going into production producing 1,000 per week. The use of a CPAP is possibly a way to treat the hypoxia without the use of the ventilator and it’s adverse affects. Does anyone know of a hospital that is trying this alternative?
My husband and I were talking about the use of cpap’s a couple of weeks ago. He’s among the high risk – on dialysis, heart issues, immune suppressed, history of frequent pneumonia, sleep apnea, etc. I told him the second he starts showing symptoms I think he should wear his cpap even when he’s awake. It really worries me about the possibility of exposure. We have been through too much over the past 25 years to lose him over a virus. We have a friend whose son is fighting for his life right now. He’s 43, married with 3 small children, very fit, no history of illness, other than being a former smoker. He quickly declined and is currently in ICU on a vent. Now he is also septic and has MRSA. It’s just heartbreaking.
Is there a way to see the actual report of the 5 patients?
To deliver service patients need use Airplanes as hyperbaic chambers (1.7 bar) see article for details:
https://docs.google.com/document/d/1_d5jdUpPs6z18V2erB-OQujk205Dm2P-vWjxpD9Cf5o/edit?usp=sharing
I would agree that the best use would be for those on oxygen preintubation . It seems That it might prevent this step as once vented it is a long road… perhaps improving organ oxygenation also
I do Hyperbaric Therapy at home years prior to coming down with a lung infection for the last 4 weeks ( my dr gave me treatments for Covid 19 as precaution) my main issue is spontaneous bad lung spasms and asthma. Since I don’t have chest congestion I’ve continued my Hyperbaric Oxygen therapy in my home, and it has made dramatic difference in my lung spasms. The results of no asthma attacks and calm lungs last about 6 hrs for me. Without it I have major lung spasms where it’s hard to breath every few minutes. I believe it’s definitely worth exploring.
Emily, do you know about EWOT? This is me; https://liveo2.com/jeff-langley/ I also believe I have been exposed to COVID by the EWOT treatments prevented it from incapacitating me.

Regarding concerns about transporting to HBOT chambers and spread of infections. Would it be feasible to use Gamow bags?
As per Dr Fife, there are many reasons to try alternatives to mechanical ventilation. The challenge as described is oxygenation. We are currently working to start a trial using portable chambers at 1.3 ATA. In stead of bringing the patient to the chamber, we will bring the chamber to the patient. I am happy to communicate with others about it.
Dr Riskins,
I would like to talk to you more about what your doing. I am a PA in Oklahoma.

If you have inflated sports facilities in your area they can support HBOT treatments on a large scale. Most of these domes can sustain ata’s of 3 for an extended period of time.
I have not seen Inflated sports facilities that can withstand such a high pressue. Do you have a link for such?
I just spoke to a Yeadon Domes rep. and he said the domes run at 1.2 most of the time, but can go to as much as 5 for heavy snow for short periods of time. They can sustain 3 for longer periods.
Smow pressure is max 1000 kg/m2. 3 ATA is 20 000 kg/cm
But if say 1.3 is realistic than one dome could be placed inside the other and 1.7 ATA is achievable. that would be a great solution..
* sorry, typo 20 000kg/m2
Using military planes as multi chanbers for treatment.

Another alternative to hospital HBOT is to reconfigure level A hazmat suits as a pressure vessel.
I wonder how to make disinfection in the mono place chamber after use.
Remember UVC is very effective against COVID19. One must protect eyes and skin but the air would be cleansed.
UV light is very harmful to chamber acrylics
If we can modify a Boeing flight 747 into a Hyperbaric oxygen chamber , then you can accommodate more number of patients in between onset of symptoms and before reaching up in ICU for ventilator support can be well treated and with the help of fresh blood transfusion and medication, I think patients will improve a lot and no need for ventilator support, which causes more damage to lungs and worsening the situation. This is my suggestion. Thanks.
electrolyzed acidic water
LOL from a nursing care standpoint, that would be a nightmare! Sweat, urine, feces, sputum, not to mention IV tubes. Yikes!
Where could one see the details of this study: description of patients, protocols? Was it published? E.g. http://chinaxiv.org/ What is the “Naval Specialty Medical Center Program Team” that published the report?
Max pressure differential on a B-777 is 9.1 psi. seems like it could work

Nick: look me up, would love to bring you in on the effort we first sent up to the White House, through various science channels, and others, many weeks ago. First person to have a crack at it was a PhD physicist faculty collesgue of Steven Hawking. Roland Delhomme, runwaysend@gmail.com
I work for a company that manufactures pressure vessels and vacuum chambers. I’m wondering if HBOT would help and I have a couple of thoughts. 1. Normally for HBOT there is some flow through the chamber to keep it comfortable and to remove CO2. The type of chambers we build would be helium leak tight so there would be a proper filter on the exit of the chamber to stop all viruses. There is no need to be concerned that the virus could contaminate the room. 2. Between each patient one could fill the chamber with pressurized ozone. I would guess that would sterilize it between patients better than any other method. 3. There is a process at the point of removing a patient where viruses could be released into the room. What do you think of asking the patient to have their N95 mask on and then flush the chamber a couple of minutes with air to carry the virus to the chamber exit before opening it? It would also keep a surge of oxygen to be vented into the room.
Finally, I have some questions. Why 1.3 ATA pressure? Why not 3 bar gage (45 psig) or a much higher pressure? Are there medical reasons you would not want to provide an atmosphere of much denser air or high concentration oxygen?
Ken
3 bar 100%O2 120min once a day is ok, but not more. 4+ bars = death due to oxygen toxicity (was tested on rabbits).
Thanks! What would be the ideal pressure and concentration for COVID-19?
That’s a complicated question.
To achieve maximum antiviral effect and maximum chamber throughput I would use 3 bar 100% oxygen 120 min once a day or 2 bar 100% 90 min – twice a day for severe cases
If there’s plenty of chambers and patients can stay inside chamber for week – 1.5 bar 40% O2 (like airplane or railway tank or gas tanker ship)
Perhaps it’s a complicated question, but your answer seems very sound. Thank You! Would you ever need to run higher pressure air with no added oxygen?
yes, if no oxygen is available of in case you need to use electronic devices that otherwise cannot be used due to fire safety. You can use 3 bars 21% oxygen (air) for unlimited period
Artem, I have another question for you. Is there a process for gradually increasing and decreasing the pressure? For example if a person goes through a load lock to enter a higher pressure area how quickly can one go up in pressure? Or if a person is in a chamber and panics and says, “I want out now!” How quickly is it safe to dump the pressure to take them out? Thanks!
1 bar per minute – maximum decompression rate in emergency case
if you want to maximize chamber throughput 10 minutes – compression/decompression rate should be fine
Ken, there are many reasons, but time constrains me at the moment. 1.6 seems to be a sweet spot, and you dodge complications from toxicity, flammability/explosion hazard and time to ramp up-ramp down, comfort, and more. I would love to hear more about the ozone-sounds like you get to work with some interesting hardware…
One more comment about using airplanes as pressure vessels, while it could technically work it the logistics are complicated. Is your hospital next to the airport? Are you going to run the jet engines for hours just to pressurize it? Once it is pressurized no one goes in and out? What about all of the other utilities and equipment you might want inside? We build helium leak tight vessels for a living and we can easily build whatever you want: an individual treatment chamber or hospital wing with load locks where you can go in and out. If the pressure is not too high even shipping containers might work as a structural element.
You can use just the fusilages. Engineers on line said it’s easy. Plus Boeing needs work.
Do we really need a ‘pressure chamber?” Fighter pilots use a pressured suit. Would not that be more practical? You could keep patent in his own ICU bed during the treatment. In an emergency you could quickly deflate and treat the patient. The suits are probably also more available then chambers?
Roland, I think it is simply a trade off between pressures, convenience and cost. Just a hood as shown here has benefit. https://www.youtube.com/watch?v=osN6lubQfDY&feature=youtu.be but the more you can do the greater the benefit. Suits have low pressure ratings
that hood can probably hold 40 pascal? HBOT is 200000 pascal.. So the benefit is tiny, but it could be used inside multi-seat hyperbaric chamber as social distancing device)
what about converting those new snorkel masks into mini-HBOT ?
https://www.bbc.com/news/av/world-europe-52120587/coronavirus-the-snorkelling-mask-that-can-help-fight-covid-19
? some modified version of the above to do just 1.3 atm?
1.3 atm = 30000 pasclal pressure differential = 0.3 kg/cm = 120kg pressure on face = not possible
My opinion is just tell us what you need. It is not the best to try to force fit something that was not made to do exactly what you want (not to mention FDA approvals). The amazing and capable manufacturers of America are ready and able to make the exact thing the medical professionals want. Once you know what you need, just write a spec and we will run with it.
Military has been using it for Covid-19 patients just not telling you which service branches and where.
Not a Dr. but I train with Oxygen (EWOT – Exercise With Oxygen Therapy – LiveO2 system). It’s the same idea as HBOT but you exercise to provide the “pressure” increase in heart and lungs, and high dose of oxygen (~85%) is provided in a large bladder pre-filled by an Oxygen Separator unit. You use a mask, not cannula. Obviously, you can’t be extremely sick or you can’t exercise.
More info; https://liveo2.com/
If you are concerned about infecting the cleaning crew, other patients, and healthcare workers; there is a possible remedy. Ultraviolet C is found to be 10 times more effective against RNA viruses than other microbes. I have been researching UVC for last 3 years and have a device in the market for disinfecting operating rooms. A simpler custom made device can be used in the chambers and I would recommend the use before and after manual antiseptic wipe down to protect the staff. It can be very effective at low doses (irradiance) and much shorter exposure time, as the volume inside the chamber is so small compared to the operating rooms.

Caroline-
We have considered using HBOT for Covid patients here in Spokane but we don’t have enough patients now. I think, based on what we are seeing, that treating patients on admission who don’t need the ICU would be most practical. The early data is showing that the ICU and ventilators can be avoided with this approach. I would not use your usual hyperbaric chamber for this but get one on a flatbed trailer and park it somewhere near a dedicated-isolated entrance to the hospital, or put a monoplace or 2 on the Covid ward. You would also need a dedicated staff. This approach might be impractical for some facilities and there is a cost. Ideally some government agency would see the wisdom of this approach and help with the funding. Just my thoughts and I hope they can help someone.
Jim Wright, MD
In absence of the chambers , improved oxygenation can be achieved with deep breathing exercises. this is where and exercise physiologist could be piped in via video to lead moderately ill patients . Take a deep breath, hold it exhale, repeat…
As an accomplished climber, mountaineer and long distance backpacker I used pressure breathing, a technique that has been around for decades that I picked up from RMI. Climbers like John Roskelly, George Dunn, Marty Hoye, Phil Ershler, the Whittakers among others were proponents. As an expedition leader and guide I also knew about Gamow bags and their use for HAPE.
You have to know a lot to stay alive in those beautiful but hostile realms. A good technique and decision well considered can save lives of your team, a bad decision can end them.
As far as I have known from my contact on Alibaba, China continues to construct, ship and after installation, commission within 15 days new multiplace HBOT chambers. They are getting ready for the fall increase of cases of Covid-19 and its attendant respiratory disease and cytokine storm.
At this time we lag woefully behind China at our national peril. Imho.
I think most of the concerns expressed here by the good doctor can be overcome quickly. We need to place the lives of our people before profit.
Sorry POTUS and U.S. Representatives, this is a medical war for the survival of people and not a way to grow your GDP, poll ratings or supporting your latest monopolistic and trust creating multinational corporation or a means to rob our futures for some overfed and overleveraged banksters in the latest version of unspoken bailouts for bad decisions impacting their fourth quarter earnings.
I have a question. Would it be helpful for COVID-19 patients to be placed on their stomach instead of their back while receiving HBOT? Could that allow even more oxygen to enter the bloodstream?
HBOT is far superior to ventilator use and if nearly every public school teacher in the nation can relearn teaching to go online in a few short months, medical professionals should be able to learn how to implement HBOT. And disinfecting is not a huge issue, nor is purchasing more chambers and getting training… ESP if California can spend billions on masks. Really? Mask versus HBOT? Shall we go back to leeches? Sad.. Very Sad. Justin bieber has an HBOT chamber, and it isn’t practical for Doctors in the U.S. to have to learn to utilize it? This is like banging nails with a rock and when someone shows you a hammer or a nail gun, you reject it as impractical.
The Winthrop hospital clinical trial is reported at Underseas Hyperbaric Medicine
This, is important to view.

Your blog is very helpful to know the fact of how HBOT is helpful to the people suffering with COVID and there are no enough chambers to be supplied to every patient. Your support during challenging times is marvellous.
