HBOT Conversations:
Dr. Peter Canaday (Part 1)
Dr. Peter Canaday has published work in Applied Physiology, Respiratory Medicine, and Diagnostic Radiology. He has presented at National (USA) and International meetings, and his research supported the eventual FDA approval of a new medical imaging device incorporating digital X-ray tomosynthesis. He has sat on National, State, and Local advisory committees, and given testimony at the State Legislative level in the USA.
Dr. Canaday’s experience with Hyperbaric Oxygen Therapy dates back to the 1980s when he studied HBOT under Dr. Eric Kindwall, “The Father of Hyperbaric Medicine”. Dr. Canaday also co-founded the Hyperbaric Medicine Department at St. Anthony Hospital in Lakewood, Colorado.
From 2007, Dr. Canaday spent time in community radiology practices before settling in New Zealand in 2013 as a Consultant Radiologist. Since 2016, he was employed at a Midlands region DHB and served as Head of Department before retiring in March 2021.

HBOT News welcomes Dr. Peter Canaday. Dr. Canaday now lives primarily in New Zealand, but his history with medicine and Hyperbaric Oxygen Therapy dates back over 40 years to the United States.
In this HBOT News Network Conversations, Dr. Canaday spends the first several minutes providing listeners with his biography and medical background. He also dives into his experience with Hyperbaric Oxygen Therapy in the 1980s.
The subject of PTSD and recent Hyperbaric research arises, and Dr. Canaday expands on the topic by referencing two research articles from Dr. Paul G. Harch –
Dr. Canaday further explains, “There is a recruitment of the anti-inflammatory enzymes and a suppression of the pro-inflammatory enzymes that can be achieved through even these lower pressure units. And so we’re beginning to see now the potential mechanism for which Hyperbaric Therapy, whether with or without oxygen, may be effective.”
The remainder of this HBOT News Conversation is specific to the topic of COVID-19. di Girolamo starts the conversation discussing the struggles for long-hauler COVID patients and the growing number of vaccine injuries as a result of the COVID-19 vaccine. Dr. Canaday agrees that the scientific inquiry for COVID-19 and the available information for associated vaccines has been widely suppressed. He continues that even the data which represent conclusions from peer-reviewed literature has been simply ignored, or set aside without discussion.
In response, Dr. Canaday provides viewers with direct links on how they can learn more about some of the data and information he’s shared with the public regarding the COVID-19 vaccine roll-outs:

Dr. Peter Canaday
Following completion of medical school at the University of Massachusetts in 1976, Dr. Peter Canaday took up training as an Internal Medicine specialist at the University of Michigan, followed by sub-specialist training in Respiratory and Intensive Care at the University of North Carolina. He began his medical career in a busy trauma hospital in Denver, Colorado in 1981 and practiced for 12 years. During his time there, he managed many of the types of patients now seen with severe COVID-19, co-founded a sleep disorders laboratory and a hyperbaric medicine department. As well, he participated in a dozen committee assignments, and rose to Chairman of the Department of Internal Medicine. In 1993, Dr Canaday changed career and completed training as a Radiologist at the University of Wisconsin in 1997. During an 8-year period at Creighton University Medical School in Nebraska, he became tenured as an Assistant Professor of Radiology, and head of the section of Pulmonary Radiology. He also served on or chaired over a dozen hospital and medical school committees and was appointed Clinical Coordinator for the Radiology Department during his time there. Dr Canaday has also published work in applied physiology, respiratory medicine, and diagnostic radiology, has presented at national (USA) and international meetings, and his research supported the eventual FDA approval of a new medical imaging device incorporating digital X-ray tomosynthesis. He has sat on national, state, and local level advisory committees and given testimony at the state legislative level in the USA. From 2007, Dr Canaday spent time in community radiology practices before settling in New Zealand in 2013 as a Consultant Radiologist. Since 2016, he was employed at the Taranaki District Health Board and served as Head of Department before retiring in March 2021.

Microglial activation induced by traumatic brain injury is suppressed by postinjury treatment with hyperbaric oxygen therapy.
The mechanisms underlying the protective effects of hyperbaric oxygen (HBO) therapy on traumatic brain injury (TBI) are unclear. TBI initiates a neuroinflammatory cascade characterized by activation of microglia and increased production of proinflammatory cytokines. In this study, we attempted to ascertain whether the occurrence of neuroinflammation exhibited during TBI can be reduced by HBO. TBI was produced by the fluid percussion technique in rats. HBO (100% O2 at 2.0 absolute atmospheres) was then used at 1 h (HBO I) or 8 h (HBO II) after TBI. Neurobehavior was evaluated by the inclined plane test on the 72 h after TBI and then the rats were killed. The infarction area was evaluated by Triphenyltetrazolium chloride. Immunofluorescence staining was used to evaluate neuronal apoptosis (TUNEL + NeuN), microglial cell aggregation count (OX42 + DAPI), and tumor necrosis factor-alpha (TNF-α) expression in microglia cell (OX42 + TNF-α). The maximum grasp angle in the inclined plane test and cerebral infarction of the rats after TBI were significantly attenuated by HBO therapy regardless of whether the rats were treated with HBO 1 or 8 h after TBI compared with the controls. TBI-induced microglial activation, TNF-α expression, and neuronal apoptosis were also significantly reduced by HBO therapy. Our results demonstrate that treatment of TBI during the acute phase of injury can attenuate microgliosis and proinflammatory cytokine TNF-α expression resulting in a neuroprotective effect. Even treating TBI with HBO after 8 h had a therapeutic effect.
