In this small pilot study, participants (patients and healthy volunteers) will have blood drawn before and after the study intervention (hyperbaric chamber session or normal pressure oxygen breathing. This blood will be analyzed for neutrophil oxidative burst and cytokine analysis.
The investigators are interested in studying the influence of hyperbaric oxygen on neutrophils (a kind of white blood cell) and cytokines (cell proteins). Hyperbaric oxygen can enhance the way the immune system works, but the investigators don't fully know how that happens. the investigators are doing this study to learn more about this question.

Carbon monoxide poisoning still places a burden on the healthcare system worldwide. While oxygen therapy is the cornerstone treatment, the role and practical modalities of hyperbaric oxyge...
The purpose of this study is to examine the role of Hyperbaric Oxygen Therapy (HBOT) in improving neurological function in patients who are 6 to 36 months post ischemic stroke.
Due its high incidence, mTBI and its consequences of PPCS are a major public health issue. There is no consensus regarding the treatment of PPCS in pediatrics. Relying on its results in ad...
The Brain uses 20% of the total oxygen supply consumed by the entire body. Even though, less than 10% of the brain is active at every given time, the brain utilizes almost all the oxygen d...
The primary purpose of this study is to assess whether hyperbaric oxygen treatment improves neurological function in patients who exhibit white matter hyperintensities on MRI examination. ...
Hyperbaric oxygen therapy (HBOT), which is a centuries-old treatment, has now increasingly often been used in the pediatric population. The basic indications for HBOT are well-known disease entities, ...
HOPON (Hyperbaric Oxygen for the Prevention of Osteoradionecrosis): a randomised controlled trial of hyperbaric oxygen to prevent osteoradionecrosis of the irradiated mandible after dentoalveolar surgery.
Hyperbaric oxygen (HBO) has been advocated in the prevention and treatment of osteoradionecrosis of the jaws following head and neck radiotherapy, but supporting evidence is weak. The aim of this rand...
During a hyperbaric oxygen therapy (HBOT) session, every medical device that is used within the hyperbaric chamber is exposed to several hazards, including an increased ambient pressure and partial pr...
To examine visual acuity, refraction and ocular status before, during and after hyperbaric oxygen therapy (HBOT).
Some clinical trials report improvement in persistent post-concussive symptoms (PCS) with hyperbaric oxygen (HBO2) following mild traumatic brain injury (mTBI), but questions remain regarding the util...
The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)
The therapeutic intermittent administration of oxygen in a chamber at greater than sea-level atmospheric pressures (three atmospheres). It is considered effective treatment for air and gas embolisms, smoke inhalation, acute carbon monoxide poisoning, caisson disease, clostridial gangrene, etc. (From Segen, Dictionary of Modern Medicine, 1992). The list of treatment modalities includes stroke.
Stable oxygen atoms that have the same atomic number as the element oxygen, but differ in atomic weight. O-17 and 18 are stable oxygen isotopes.
Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of signal transduction and gene expression, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.
Unstable isotopes of oxygen that decay or disintegrate emitting radiation. O atoms with atomic weights 13, 14, 15, 19, and 20 are radioactive oxygen isotopes.
Cytokines include chemokines, lymphokines, and monokines. Cells of the immune system communicate with one another by releasing and responding to chemical messengers called cytokines. These proteins are secreted by immune cells and act on other cells to...
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
