Hyperbaric oxygen therapy – HBOT – is a method of treating diseases and injuries in a hyperbaric chamber that uses a pressure higher than the atmospheric one.
It bases on administering to the subject oxygen in the pressurized area. With the increased pressure the migration of oxygen into body cells is accelerated, hich increases their oxygen, speeding cell’s regeneration and development.
When breathing air at normal atmospheric pressure, oxygen is transported by the hemoglobin inside red blood cells. During hyperbaric oxygen therapy patient breathes air with increased oxygen, which causes a significant increase in hemoglobin oxygen saturation. This in turn increases the amount of free oxygen in body fluids, allowing better blood supply to body tissues.
Under the increased pressure oxygen easily dissolves in the blood plasma and core – cerebral liquid, lymph and other body fluids, and is therefore easily supplied to all tissues, even those with relatively poor blood supply. As a result, even those areas which were previously deprived of oxygen benefit greatly from the treatment.
The pressure under which the patient lies during treatment is the sum of atmospheric pressure and the one in the chamber. This pressure is expressed in atmospheres absolute (ATA). Currently hyperbaric pressure within the range of 1.3 to 3.0 ATA is being used.
Our hyperbaric chamber’ pressure is set on 1.5 ATA – which is sufficiently effective and safe for the treatment purposes. Normally, a single treatment lasts 60 to 90 minutes. During this time patient stays in a chamber filled with compressed air, breathing pure oxygen through the mask.
As clinical research show, typical amouint of the oxygen that gets dissolved in blood’s plasma under normal atmopsheric pressure ranges around 3 ml per blood litre, while during the respiration with pure oxygen only its amounts increases to 20 ml per litre!
The primary result of the hyperbaric therapy is the increase of the oxygen ‘ amount in patient’s body, as well as:
- increasing the oxygen supply to the damaged area of the body
- improving blood circulation in the area damaged by the central vasoconstriction and increase the flow of the oxygen through the damaged tissue
- reducing the swelling of damaged tissue
- inhibiting bacterial growth and enhancing the effectiveness of antibiotics
- activating angiogenesis
proliferating of dermis cells and increasing the production of collagen
- increasing in antimicrobial activity
- increasing the osteoblasts and osteoclasts’ activity
- reducing the half-life of carboxyhemoglobin
- reducing the volume of the gas bubbles in the blood
The following indications are approved for the use of hyperbaric oxygen therapy :
- Air or gas embolism
- Carbon monoxide poisoning
- Carbon monoxide poisoning complicated by cyanide poisoning
- Central retinal artery occlusion
- Clostridal myositis and myonecrosis (gas gangrene)
- Crush injury, compartment syndrome, and other acute traumatic ischemias
- Decompression sickness
- Enhancement of healing in selected problem wounds
- Diabetically derived illness, such as diabetic foot,diabetic retinopathy, diabetic nephropathy
- Exceptional blood loss (anemia)
- Idiopathic sudden sensorineural hearing loss
- Intracranial abscess
- Necrotizing soft tissue infections (necrotizing fasciitis)
- Osteomyelitis (refractory)
- Delayed radiation injury (soft tissue and bony necrosis)
- Skin grafts and flaps (compromised)
- Thermal burns
In the year 2015 the number of people utilizing hiperbaric oxygen therapy in autism, cancer, diabetes, HIV/AIDS, Alzheimer’s disease, asthma, Bell’s palsy, cerebral palsy, depression, heart disease, migraines, multiple sclerosis, Parkinson’s disease, spinal cord injury, sports injuries and strokes have rised rapidly, due to its benefitial impact on the above mentioned inflictions.
