Reversibility of retinal ischemia due to central retinal artery occlusion by hyperbaric oxygen

Ischemic retinal damage can be reversed by hyperbaric oxygen therapy (HBOT) as long as irreversible infarction damage has not developed. However, the time window till irreversible damage develops is still unknown. The study aim was to evaluate the effect of HBOT and determine possible markers for irreversible retinal damage. Retrospective analysis of 225 patients treated…

The effects of hyperbaric oxygen therapy on diabetic retinopathy: A preliminary study

The objective of this study was to prospectively assess the effect of hyperbaric oxygen therapy (HBOT) on diabetic retinopathy lesions and macular edema in patients undergoing the treatment for diabetic foot ulcers. We compared two groups: a first group including 25 patients with non-proliferative diabetic retinopathy treated by HBOT for foot ulcers, and a second…

The Effect of Mild-Pressure Hyperbaric Therapy (Oasis O2) on Fatigue and Oxidative Stress

Mild-pressure hyperbaric therapy (mHBT) has become increasingly popular among elite athletes and most recently among the general public yet there is very little scientific underpinnings on its therapeutic use. In this study, fifteen healthy volunteers (8 men, 7 women, mean age 29.7 ± 8.1 years) were exposed to 1.3 atmospheres absolute (ATA) for 40 minutes…

Comparative study of the effectiveness of a low-pressure hyperbaric oxygen treatment and physical exercise in women with fibromyalgia: randomized clinical trial

Fibromyalgia (FM) is characterized by chronic pain and fatigue, among other manifestations, thus advising interventions that do not aggravate these symptoms. The main purpose of this study is to analyse the effect of low-pressure hyperbaric oxygen therapy (HBOT) on induced fatigue, pain, endurance and functional capacity, physical performance and cortical excitability when compared with a…

Hyperbaric oxygen treatment of fibromyalgia: a prospective observational clinical study

Fibromyalgia (FM) is a syndrome of unknown aetiology that is characterised by widespread musculoskeletal pain, fatigue and disordered sleep, and often associated with neuropsychiatric and cognitive symptoms. Current treatment options are only partially effective, but hyperbaric oxygen therapy (HBOT) seems to be capable of relieving some of the symptoms. The aim of this study was…

Hyperbaric oxygen treatment for inflammatory bowel disease: a systematic review and analysis

Traditionally, hyperbaric oxygen treatment (HBOT) has been used to treat a limited repertoire of disease, including decompression sickness and healing of problem wounds. However, some investigators have used HBOT to treat inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis. Comprehensive searches were conducted in 8 scientific databases through 2011 to identify publications using…

Repetitive hyperbaric oxygen treatment attenuates complete Freund’s adjuvant-induced pain and reduces glia-mediated neuroinflammation in the spinal cord

Hyperbaric oxygen (HBO) therapy is reported to attenuate pain in both clinical pain conditions and animal pain models, but the underlying mechanism remains to be investigated. Here, we show that 7 daily 60-minute HBO (100% oxygen, 2 atmosphere absolute) treatments effectively and persistently inhibited heat hyperalgesia, mechanical allodynia, and paw edema induced by peripheral injection…

Hyperbaric oxygen induces a cytoprotective and angiogenic response in human microvascular endothelial cells

A genome-wide microarray analysis of gene expression was carried out on human microvascular endothelial cells (HMEC-1) exposed to hyperbaric oxygen treatment (HBOT) under conditions that approximated clinical settings. Highly up-regulated genes included immediate early transcription factors (FOS, FOSB, and JUNB) and metallothioneins. Six molecular chaperones were also up-regulated immediately following HBOT, and all of these…
