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.

Brain perfusion imaging with voxel-based analysis in secondary progressive multiple sclerosis patients with a moderate to severe stage of disease: a boon for the workforce.
The present study was carried out to evaluate cerebral perfusion in multiple sclerosis (MS) patients with a moderate to severe stage of disease. Some patients underwent hyperbaric oxygen therapy (HBOT) and brain perfusion between before and after that was compared. We retrospectively reviewed 25 secondary progressive (SP)-MS patients from the hospital database. Neurological disability evaluated by Expanded Disability Status Scale Score (EDSS). Brain perfusion was performed by (99 m) Tc-labeled bicisate (ECD) brain SPECT and the data were compared using statistical parametric mapping (SPM). In total, 16 patients underwent HBOT. Before HBOT and at the end of 20 sessions of oxygen treatment, 99mTc-ECD brain perfusion single photon emission computed tomography (SPECT) was performed again then the results were evaluated and compared. Brain perfusion was performed by (99 m) Tc-labeled bicisate (ECD) brain SPECT and the data were compared using statistical parametric mapping (SPM). A total of 25 SP-MS patients, 14 females (56 %) and 11 males (44 %) with a mean age of 38.92 ± 11.28 years included in the study. The mean disease duration was 8.70 ± 5.30 years. Of the 25 patients, 2 (8 %) had a normal SPECT and 23 (92 %) had abnormal brain perfusion SPECT studies. The study showed a significant association between severity of perfusion impairment with disease duration and also with EDSS (P <0.05). There was a significant improvement in pre- and post-treatment perfusion scans (P <0.05)
[Efficacy of hyperbaric oxygen therapy in the treatment of ischemic toe ulcer in a patient presenting systemic sclerosis].
The medical treatment of ischemic ulcers in patients with systemic sclerosis remains difficult. Despite the major help provided by vasodilator treatments, the risk of spontaneous or surgical amputation remains high. A 48-year-old female patient from Guadeloupe was treated in our department for diffuse systemic sclerosis present for 15 years complicated by lung, joint and digestive involvement, and associated with severe Raynaud’s phenomenon. The clinical course was marked by the occurrence of multiple ischemic ulcers, which were resistant to conventional medical treatment and resulted in two surgical amputations (to the 2nd and 3rd interphalangeal joints of the toes of the left foot). Treatment with an endothelin-receptor antagonist and a calcium inhibitor was then introduced for secondary prevention. Two years later, the patient consulted for a further ischemic ulcer of the left 4th toe. She refused the proposed treatment with iloprost. Because of the unfavorable outcome and the absence of therapeutic alternative to amputation, hyperbaric oxygen therapy was initiated. Thirty 90-minutes sessions of pure oxygen at 2.5 ATA were conducted over a 10-week period. Complete healing was obtained after 8 months. We report herein a clinical case illustrating the efficacy of hyperbaric oxygen therapy for the treatment of ischemic ulcers of the toes in systemic sclerosis.
