Twenty firefighters with mTBI and mild emotional distress were treated with HBO at a relatively low pressure of 1.3 atmospheres absolute for 45 min a day for 20 consecutive day. The goal of the study was to evaluate the subsequent changes in the regional cerebral blood flow (rCBF) of the limbic system in these firefighters. The results showed an increase in rCBF in the hippocampal and parahippocampal regions of the brain. This may explain the recent evidence that suggests the ability for HBOT to help neural activities in the human brain and subsequently improve symptoms of psychiatric disorders <view study> Read Less

This animal study used hyperbaric oxygen at 1.5 ATA as a supportive therapy following surgery. They gave 5 daily sessions following the surgical procedure. The post operative results in this hyperbaric group showed an improvement in the wound healing with quicker healing time, fewer complications, and earlier skin suture removal <view study> Read Less

Bone loss is a common problem seen in the aging population, mainly due to disuse. This is also a seen in astronauts, patients that are on extended bed rests, and in people leading a sedentary lifestyle. Disuse-induced Bone Loss is can lead to osteoporosis and higher risks of bone fractures. When bones are more frequently subjected to mechanical loads (i.e. weight-bearing exercise), bones adapt by increasing in bone mass. The opposite occurs when the bones are not regularly exposed to mechanical loads leading to a loss of bone mass and increased risk of fracture. In this study, a 10 day course of mild hyperbaric therapy (1.3 ATA) was shown to protect and counter disuse-induced bone loss while helping to enhance new bone formation. <view study> Read Less

A total of 53 patients (42 with Alzheimers disease and 11 mild cognitive impairment) were treated with a 20 day course of hyperbaric oxygen therapy. Each hyperbaric session consisted of 3 sequential parts; first, 20 minutes of oxygen breathing, followed by 15 minutes of breathing air, and finally 20 minutes of breathing oxygen under pressure at 1.2 ATA. Results — One course (20 sessions) of hyperbaric oxygen therapy significantly improved cognition in both Alzheimer patients and patient with Mild Cognitive impairment, with the latter having more long term benefits (> 1 month). These results are very promising for Alzheimer patients, and suggest that it is possible that multiple courses might be the solution for giving significantly longer benefits to AD patients. More research is still needed <view study> Read Less

This study was used to evaluate the effects of low-pressure hyperbaric oxygen therapy (HBOT) on fatigue, pain, endurance and functional capacity, physical performance and cortical excitability when compared with a physical exercise program in women with fibromyalgia. The hyperbaric protocol used was a 2 month course of daily 90 minute sessions (5 days per week for a total of 40 hours) at 1.45 ATA. During this time period, 60 minutes of low intensity exercises, twice weekly (for a total of 16 sessions), was included in the protocol. This group of participants showed improvements in pressure pain threshold, endurance and functional capacity, as well as physical performance. In addition, the HBOT group reported significant improvements in induced fatigue and perceived pain at rest. <view study> Read Less
