In a Special 5-part series with Extivita’s Nurse Practitioner, Elena Schertz, and Safety Director, Tom Fox, we dive into the extraordinary HBOT healing they have witnessed for a variety of conditions. In Part 1 of 5, we discuss PTSD among the veteran community.
Tom Fox has been involved in the hyperbaric field for 31 years, and is considered an International historian for Hyperbaric Oxygen Therapy. He has extensive experience treating severely injured veterans, with his first experiences dating back to the landmine wounds of the first Persian Gulf War. With his wife, Claudine, by his side they have treated up to 42,000 individuals (for all conditions) with Hyperbaric Oxygen Therapy. He explains that there is nothing quite like getting hugs from veteran family members who have seen their loved ones “come back to life” after having suffered from PTSD for a long period of time. Tom has spent his career educating others on the power of Hyperbaric Oxygen Therapy, with the veteran community being very near and dear to his heart. Tom explains that during combat these troops see extraordinary pressure changes, especially with primary blast injuries that are not visible. He has written many articles on this subject matter and has been called upon as an expert in governmental presentations relative to the effects of pressure on the human body.

- WHITE PAPER: Hyperbaric Oxygen Therapy: A Therapy Capable of Significant Improvements in the care of Veterans with Signature (Silent) Wounding
Elena Schertz, the Nurse Practitioner and clinic manager at Extivita-RTP, is no stranger to HBOT News and has been interviewed on HBOT News previously. She has been a nurse for 25 years, and has a background in primarily Pediatric Oncology, with some experience in the Cardiology field. 13 years ago, Elena became involved with integrative medicine, which eventually landed her at Extivita for the past four years where she has treated over 1,000 patients with Hyperbaric Oxygen Therapy.
Both Tom and Elena continue to be heavily involved with the veteran community. In fact, Extivita treats veterans under a program that funds North Carolina veterans to receive HBOT treatments for free. By using HBOT, they have been successful in treating PTSD, post-concussion symptoms, sleep disorders, quality & quantity of life, cognitive function, executive function, anxiety and depression — all of which are known symptoms that HBOT helps, and has been acknowledged in medical journals. Elena states that probably 99% of the veterans that are treated at their clinic have improved significantly.
Tom and Elena explain how Hyperbaric Oxygen helps veterans overcome PTSD symptoms – allowing them better sleep, improved relationships, and diminished suicidal thoughts. They also stress the importance of family, and how it’s truly critical for a veteran to have a caregiver helping and encouraging them through the entire process of care when they return home from the battlefield.
Tom tells a story of General Patt Maney. General Maney was injured in an IED explosion that destroyed the entire vehicle, and he suffered severe invisible injuries. General Maney had a very serious brain injury that left him with almost no short-term memory, and he was at mercy of his wife for almost a year. He was a laywer on the bench in the state of Florida, but his injury was preventing him from reentering. He was eventually treated by Dr. Eddie Zant with Hyperbaric Oxygen Therapy. His recovery was so amazing that he was able to reenter the law practice and sit as a judge! He established a veterans court system, and remains an integral piece in reforming the legislative approaches to the management of those veterans that have gone astray in the legal world.
PTSD can be completely life-altering for veterans, but Hyperbaric Oxygen Therapy is proving that it can and will give them their lives back. HBOT allows military service members to finally be able to sit at Thanksgiving dinner and not have to leave because the noise and stimulation is too much. Seeing our veterans finally heal has been one of the most rewarding things for Elena and Tom.
If only HBOT could be available to the active warfighter, someone that’s in the field and just got rattled by an IED. We would not only be sending our troops home with a healthier and clearer mind, we’d be healing the invisible battle wounds of war in a fraction of the time.
Join us next week for Part 2, when Tom and Elena will dive into a discussion about concussions.

Clinical Trial – Effects of Repetitive Hyperbaric Oxygen Therapy in Patients With Acute Ischaemic Stroke
Background and Rationale:
Cerebrovascular disease is always ranked at the top causes of death and most of hospitalized
acute stroke patients have ischemic stroke [1].
Although the mortality rate of acute ischemic stroke is less than that of hemorrhagic stroke
[1], it still results in patient disabilities and complications that often lead to
significant costs to individuals, families, and society.
Traditional treatment for acute ischemic stroke includes thrombolytic therapy by injecting
tissue plasminogen activator (t-PA) within three hours after onset of symptoms [2],
antiplatelets and/or anticoagulant agents administered within the first 48 hours. Clinically,
the narrow time window of thrombolytic therapy and coexisting contraindications limit the use
of t-PA [2]. Thus, searching for an effective supplemental treatment for acute ischemic
stroke is imperative.
Hyperbaric oxygen therapy (HBOT) is valuable in treating acute carbon monoxide poisoning
[3,4], air or gas embolism [5], facilitating wound healing [6] and has been used as an
adjuvant treatment for many neurological disorders that need further study as concussion [7]
, stroke [8,9], cerebral palsy [ 10],traumatic brain injury [ 11], cerebral air embolism
[12], Autism [13] and multiple sclerosis [14].
Indications of hyperbaric oxygen therapy recommended by undersea and hyperbaric medical
society (UHMS) [15] are 1.air or gas embolism [5], 2.carbon monoxide poisoning [3,4],
3.clostridial myositis and myonecrosis [16], 4.crush injury, compartment syndrome and other
acute traumatic ischemias [17], 5.decompression sickness [18], 6.arterial insufficiencies
[19], 7.severe anemia [20], 8.intracranial abscess [21], 9.necrotizing soft tissue infections
[22],10. refractory osteomyelitis [23], 11.delayed radiation injury [24], 12.compromised
grafts and flaps [25], 13.acute thermal burn injury [26] and 14.idiopathic sudden
sensorineural hearing loss [27].
Known mechanisms of HBOT-induced neuroprotection include enhancing neuronal viability via
increased tissue oxygen delivery to the area of diminished blood flow, reducing brain edema,
and improving metabolism after ischemia [28,29]. Furthermore, a recent study performed on a
rat suggested that upregulation of the expression of glial derived neurotrophic factor (GDNF)
and nerve growth factor (NGF) might underlie the effect of HBOT [30].
The effectiveness of use of Hyperbaric oxygen therapy in human ischemic stroke is still
controversial that need further evaluation.
Clinical Trial – Effect of Adjuvant Hyperbaric Oxygen Therapy on Bells Palsy Outcome
This is a randomized, single blinded, non-placebo controlled that will compare one group of
Bells Palsy patients receiving the current standard of care including oral corticosteroids
and oral antivirals against an experimental group receiving the current standard of care in
addition to hyperbaric oxygen therapy. Outcome assessment will be based on both objective
analyses of facial movements as well as subjective quality of life scales.
