What You Should Know About Oxygen Therapy for Stroke Patients

What You Should Know About Oxygen Therapy for Stroke Patients

If you’re looking for a treatment to improve movement after stroke, as well as other stroke side effects, then oxygen therapy could be for you.

What Is Oxygen Therapy?

Oxygen therapy, formally known as Hyperbaric Oxygen therapy (HBOT), exposes you to pure oxygen, which increases the amount of oxygen in the brain.

HBOT is administered in a clear chamber where patients lie for about 60-90 minutes breathing 100% oxygen.

A Little Background Info

To understand how oxygen therapy works, you need to understand how neuroplasticity works too.

During neuroplasticity, the surrounding parts of the brain take over the responsibility of the damaged part of the brain by building new connections between brain cells.

In order to trigger this rewiring process, you need to stimulate the brain through repetitive practice.

For example, if you need to regain leg movement, then you can only trigger neuroplasticity by practicing leg movements over and over.

Repetitive practice is the essential ingredient in effective rehab.

Now, how does oxygen therapy fit into that process?

How Oxygen Therapy Works

According to Science Daily, the brain consumes 20% of the body’s oxygen – but that’s only enough to operate a small percentage of brain cells at any given point in time.

When the brain is busy rebuilding connections through the process of neuroplasticity, it takes up even more oxygen.

Oxygen therapy provides extra oxygen to the brain, essentially working as ‘brain food,’ which speeds up the process of neuroplasticity.

While repetitive practice is the primary driver of neuroplasticity, HBOT can play a secondary role by rapidly speeding up the process.

So, there’s no escaping the hard work of rehab – but HBOT can provide a potentially powerful boost.

What Stroke Deficits Does It Treat?

Oxygen therapy is currently being used to improve movement after stroke – even for survivors suffering from post-stroke paralysis.

Some studies report that patients experience benefits like reversal of paralysis, increased sensation, and renewed use of language, which can do wonders for a survivor’s sense of independence.

Who Can Try Oxygen Therapy?

Stroke survivors can try HBOT at any stage in their recovery. It doesn’t matter if your stroke was a few months or many years ago; although most studies were conducted in the early stages.

However, Dr. Efrati has seen improvement in patients up to 20 years post stroke – and he’s the Director of the Sagol Center for Hyberbaric Medicine and Research; which, according to TedX, is the largest most occupied hyperbaric center in the world!

So, take it from a doctor who spends his entire work-life with HBOT.

Oxygen therapy has the potential to help stroke survivors at any stage post-stroke.

What Are the Side Effects?

Like all emerging treatments, HBOT comes with some risks.

Surprisingly, the greatest risk with HBOT actually comes from the treatment equipment. Since compressed pure oxygen is a fire hazard, malpractice in a HBOT chamber can lead to explosion and even death.

For this reason, it’s important to find a VERY credible HBOT administrator!

What Do the Studies Say?

Because HBOT is new, the studies so far are VERY MIXED.

Some of the studies say that it DOES NOT work:

“Although our HBO protocol appears feasible and safe, it does not appear to be beneficial and may be harmful in patients with acute ischemic stroke.” – Daniel E. Rusyniak, MD, et al.

“The overall evidence is insufficient to determine the effectiveness of hyperbaric oxygen therapy in any subgroup of stroke patients. To determine if hyperbaric oxygen therapy for stroke provides any benefit and that these outweigh potential harms, good quality studies are needed.” –Susan Carson, et al.

Some of the studies say that it DOES work:

“The results of HBO therapy in the treatment of patients with stroke, atherosclerosis, cerebral palsy, intracranial pressure, headache, and brain and spinal cord injury are promising and warrant further investigation.” –Noori S. AL-Waili, et al.

“The results indicate that HBOT can lead to significant neurological improvements in post stroke patients even at chronic late stages.” –Shai Efrati, et al.

In that study, HBOT was given to 30 stroke survivors for two months. After these two months, the HBOT survivors improved significantly more than those who didn’t receive the oxygen therapy – and they reported a better quality of life.

What all this means:

Currently, oxygen therapy is hit-or-miss. Try it at your own risk.

Although you may find yourself thinking, “What’s the point?”, there are many survivors who have completely lost hope, and solutions like HBOT can give them the boost they need to continue recovery.

Do you know someone who has tried oxygen therapy for stroke recovery? Do you want to try it yourself?

    I have had 5treatments so far and have five more scheduled I have more movement in my arm since the treatment so will see after I am done with it

    • Flint

      That’s so great to hear Marie! I’m glad it’s working for you 🙂

  • Maretta Casey

    Will hyperbaric oxygen therapy work if you take the treatment for 1 hour five days a week. Or do you have to take Hbot for 1 1/2 hours five days a week?

    • Flint

      Hey Maretta! That would be a question best suited for your doctor or neurologist! They can assess your unique situation and determine what’s safe for you.

  • Marie Frisch-Koehler

    I had hyperbaric treatment now ten times and every time after that my fingers move more so I will continue to go

    • Flint

      Hey Marie! I’m really glad to hear that it’s helping! It has been about a month since you posted that comment. How has treatment been going?

  • Debbie McCright

    I have scheduled my father for stem cell therapy with hyperbaric treatments to follow. I am nervous that I am giving “false” hope for ANY recovery. I see it as “last resort” to the traditional therapy that he is given 3 days/week. He is improving slowly with the traditional therapy but see him waning week after week with hopelessness.

    • Flint

      Hey Debbie! Those are very advanced treatment options, and I am excited to see if they will help! And I personally don’t think that you’re giving false hope. All hope is the good kind of hope during stroke recovery. I know that traditional therapy can produce slow results sometimes, but here’s an article that explains how to help speed things along: https://www.flintrehab.com/2016/benefit-stroke-rehab-exercises/

      It also sounds like you may enjoy our stroke recovery book called Healing & Happiness After Stroke. It talks about the mental game of recovery and provides ways to keep motivation and self-esteem up during times like these. Here’s the link if it resonates: https://www.flintrehab.com/product/healing-and-happiness-after-stroke-book/

      Best of luck to your father!

      • Debbie McCright

        Thank you Flint. I am going to look for that book. He definitely gained, if nothing else, a new level of hope and determination. The stem cell treatment went well and is back home doing his “dives”, as we like to call them, in his chamber. I have seen some little positive changes in his ability to speak and cognition. I would recommend the stem cell treatment for anyone with ability to travel and have it done. The advantages highly outweigh the risks. I am excited to see what the next few months have in store for him.

        • Denise


          Which facility did you receive the stem cell treatment at? Did they harvest cells from his fat? How many treatments did he receive? How much do you think it has helped? Where was he in his recovery? I am desperately seeking treatment options for my Dad. He is 18 months post stroke. Best of luck in his recovery!

          • Jna

            Like Denise, I am seeking options for my sister. She is only 52 and has teen sons to raise. Right now she is in a nursing home facility because she is unable to walk or use her arms much. I am desperately searching for treatment protocols to help her regain her independence. Congratulations and best wishes to you and your dad for his continued recovery.

          • Denise


            Sorry to hear about your sister. There is currently a nationwide double blind stem cell clinical trial going on that has had great results. It is being conducted by Stanford and candidates must be 6 to 60 months post stroke. Google SB623 stem cells and check it out on clinicaltrials.gov. My Dad recently went through the procedure, but we’re pretty certain he received the placebo, so we’re back to square one. Best of luck in your journey.

    • Julie Jean

      Any update on how Hyperbaric treatments went? I’m hoping your fathers recovery is going well.

      • Debbie McCright

        Hi Julie Jean, the stem cell treatment was “smooth sailing”. Lots of bruising but right after the treatment we went out for dinner. My dad is all in with the hyperbarics now and is encouraged as he is recognizing his right side more. His peripheral sight is getting better and now blurts out words that he is thinking. It is still slow but with each and every HB treatment he comes out with loads of energy and full of smiles and optimism.

  • Ray Harvey

    I’ve had hyperbaric oxygen therapy with great results, had 3 treatments of 30 days each, 1 hour a day at 2.5 atmospheres. I started in wheelchair and completely mute. Within a week i was walking to the chamber. I started talking within a month. Still improving my walking and speech. My arm and hand are a work in progress. Go for it
