In a Special 5-part series with Extivita’s Nurse Practitioner, Elena Schertz, and Safety Director, Tom Fox, we dive into the extraordinary powers of HBOT, and the healing they have witnessed for a variety of conditions. The following segments preluding are as follows:
Part 1 – HBOT for PTSD (veteran focus)
Part 2 – Concussions & HBOT
In Part 3 of 5, we discuss heart disease and how HBOT can help. Tom explains that one of the first cardiac patients he treated with HBOT was a necrosing cardiac surgical patient who had a necrosing sternum. The patient’s sternum was black before treatment, and after it was a fuchsia from the returned blood flow! The cardiac surgeon’s face was priceless as he witness this patient have such an incredible response to HBOT.
Tom states, “I think a lot of the physicians that are out there today, their reason why they haven’t considered hyperbarics is because they haven’t been exposed to it. If they were exposed and they could see what it was capable of doing, it would make the difference.”
Elena informs our host that she hasn’t had anyone come to Extivita to receive HBOT specifically for heart disease, but she has witnessed patients who were getting treated for other conditions benefit from HBOT for heart health. This is known through ejection fraction measurement, as Elena describes…
“I could say from about three people who have have reported improved ejection fraction from doing hyperbarics alone.”
di Girolamo reflects on a story where he heard from two HBOT patients in their late 60s, who had less than 50% heart function. They started to use hyperbarics for other reasons, and discovered that after 28 HBOT treatments they now had 70% heart function. When the Cardiologist asked with amazement, “What did you do?!”, they said we didn’t do anything — just HBOT diving.
The topic of myocarditis arises, and how HBOT can help. Myocarditis is inflammation around the heart, and in this case, hyperbaric oxygen therapy could have an intimate role in bringing about improvement to the condition. Tom continues to explain how people want to see studies, but most of the studies out there on HBOT are simply not good.
There’s never been a lot of studies about hyperbarics, and the structure of the studies comes into question. Because when we look at the hyperbaric studies that are out there, you look and see that they’re always comparing hyperbarics to slightly pressurized room air. You’ll see that traditionally how they write it up and it could be cerebral palsy, it could be post-traumatic stress disorder, the same write up, just replace the words. Both groups improved from baseline. However, there was no differentiation between the groups.
Tom goes into a discussion about a PhD student at the University of Wisconsin who went the extra mile and looked at the therapeutic effects of hyperbaric air – hyperbaric air at 1.3, slightly pressurized room air. And what he was able to do is document mobilization of stem cells. By doing so, that encouraged the medical community to rethink hyperbaric studies using hyperbaric air as the “control”.
Tom continues to dive into HBOT and heart health in general….
“Just by basis of how hyperbarics works, you can see why that did work, how that was very helpful for these folks who had myocardial infarctions. So with with the re-oxygenation of the heart, with the stem cell mobilization, with growth of new blood vessels, you could see how the heart does start to basically regenerate and get better and heal.”
When your heart is damaged from a heart attack, it’s like a wound in one of your organs or muscle. Hyperbarics is known to be incredibly beneficial for wound care, 1500 hospitals across our nation have HBOT chambers that are used often simply for wound care. So, if hypoxia and the inflammation resulting from a cardiac event is causing damage to the heart, hyperbaric oxygen therapy will work to naturally resolve and remove those two things. di Girolamo stresses that you don’t have to be an expert in HBOT to understand this, and if he had a bad heart he’d most certainly be getting hyperbaric treatments, and encourages you to do the same.
They mention that if you were to have a heart attack, inside a hyperbaric chamber is exactly where you’d want to be so you’re supersaturated with oxygen. This leads into the reasons why it’s important to pre-condition your body with oxygen prior to heart surgery, or really even any surgery. Tom references a study, “Research report: the effects of hyperbaric oxygen preconditioning on myocardial biomarkers of cardioprotection in patients having coronary artery bypass graft surgery” and explains that prepping your body for surgery can be critical in achieving a better outcome.
Tom explains, “The number one complication out of cardiac bypass surgery is post-cardiac surgical stroke. If you can actually precondition, you can avoid this.”
Cost savings and money for health and wellness remains a hot topic. Tom educates us that one of the chief things that has always been identified with how health care is practiced in the United States and Canada is it’s a for-profit industry. But, if we looked at reinstituting a payment process that actually rewarded people for being healthy, managing patients, and avoiding conditions, then we could transition the current medical industrial to be incentivized to make people healthier. If there was a way to ever do that, using hyperbaric oxygen therapy as one of the key treatments would surely be a huge leap in the right direction.

Cerebral hypoperfusion in autism spectrum disorder
Cerebral hypoperfusion, or insufficient blood flow in the brain, occurs in many areas of the brain in patients diagnosed with autism spectrum disorder (ASD). Hypoperfusion was demonstrated in the brains of individuals with ASD when compared to normal healthy control brains either using positron emission tomography (PET) or single‑photon emission computed tomography (SPECT). The affected areas include, but are not limited to the: prefrontal, frontal, temporal, occipital, and parietal cortices; thalami; basal ganglia; cingulate cortex; caudate nucleus; the limbic system including the hippocampal area; putamen; substantia nigra; cerebellum; and associative cortices. Moreover, correlations between symptom scores and hypoperfusion in the brains of individuals diagnosed with an ASD were found indicating that the greater the autism symptom pathology, the more significant the cerebral hypoperfusion or vascular pathology in the brain. Evidence suggests that brain inflammation and vascular inflammation may explain a part of the hypoperfusion. There is also evidence of a lack of normal compensatory increase in blood flow when the subjects are challenged with a task. Some studies propose treatments that can address the hypoperfusion found among individuals diagnosed with an ASD, bringing symptom relief to some extent. This review will explore the evidence that indicates cerebral hypoperfusion in ASD, as well as the possible etiological aspects, complications, and treatments.
Clinical Trial – Spinal Anesthesia in Caesarean Section
Spinal anesthesia is a safe technique, widely used and tested in the gynecological field, so
as to be considered the first choice technique in cesarean section, which allows to quickly
obtain a valid sensor and motor block. Bupivacaine is one of the most widely used drug for
obtaining spinal anesthesia in pregnant women undergoing caesarean section. Bupivacaine is a
local anesthetic available as a racemic mixture of its two enantiomers, the R (+)-
dextrobupivacaine and the S (-) – levobupivacaine, whose clinical use is widely validated.
Racemic bupivacaine is available as a simple or hyperbaric solution, the latter being the
most commonly used for spinal anesthesia. Levobupivacaine, which is the pure levorotatory
enantiomer of racemic bupivacaine, is a slightly hypobaric solution compared to liquor and
has shown less heart and nerve toxicity, probably due to its ability to bind proteins more
rapidly, and a greater selectivity towards the sensory component compared to Bupivacaine,
presents action and effects better predictable. Its baricity would also offer the advantage
of providing a less sensitive block to the position.
Hypotension is one of the most common complications of spinal anesthesia and is particularly
relevant in caesarean section because, in addition to the adverse effects on the parturient,
it can have repercussions on the fetus through a reduction of placental perfusion.
Some studies have showed a similar incidence of hypotension in patients treated with
bupivacaine compared to those treated with levobupivacaine, while others assert an
equivalence between the two drugs. In most studies, however, a significantly lower incidence
of hypotension and a greater hemodynamic stability were reported in pregnant patients
undergoing spinal anesthesia by caesarean section with levobupivacaine.
Being both hyperbaric bupivacaine and levobupivacaine routinely used at the "G. Rodolico"
Universitary Hospital of Catania for the spinal anesthesia of pregnant women undergoing
caesarean section and being their use decided exclusively at discretion of the treating
anesthesiologist, in the light of the discrepant data in the literature about the incidence
of hypotension with the two drugs, the main objective of this observational study is to
evaluate the hemodynamic effects mediated by levobupivacaine on pregnant women subjected to
elective cesarean section and to compare them with those mediated by hyperbaric bupivacaine
in an historical court of pregnant women subjected to caesarean section in the period between
April 2017 and April 2018. The hemodynamic parameters will be monitored in real time with a
non-invasive hemodynamic monitoring system (EV1000® platform + Clearsight® system – Edwards
LifeSciences), routinely used in the "G. Rodolico" Universitary Hospital of Catania, allowing
to obtain greater accuracy and veracity of the results compared to previous studies conducted
on such anesthetics.
