Hyperbaric oxygen therapy, also known as HBOT, utilizes oxygen at an air pressure higher than 1 atmosphere absolute (ATA). Under the pressurised environment, the oxygen dissolves into the blood plasma saturating the fluid and bringing about a wide range of positive cellular, biochemical, and physiological effects. HBOT has been demonstrated as a trusted, non-invasive form of treatment to increase oxygen levels in the organs of our body. Generally, an HBOT session can continue for about 60 to 90 minutes.
Several clinical research demonstrated HBOT’s innate capability of enhancing the body’s natural healing abilities. HBOT is used as a supplementary form of therapy to boost the healing process in both acute and chronic health conditions.
The roots of hyperbaric therapy used as a treatment, can be traced back to the 1600’s. Henshaw, a clergyman from Britain, is credited with building and operating the first hyperbaric chamber in 1662. He created a tilted structure called the Domicilium, which was used for a range of conditions. Years later, in 1878 French physiologist, Paul Bert discovered the connection between nitrogen air bubbles and decompression sickness and found out that recompression can lessen the pain.
Dr Orville Cunningham, an anaesthesia professor, in the early 1900’s noted that people suffering from some particular heart ailments improved better when they stayed closer to the sea level than living at higher altitudes. After the successful treatment of a colleague, who was dying due to influenza and lung restriction, Cunningham started the “Steel Ball Hospital” on the shore of Lake Erie in 1928. The hospital was a six storey high steel ball structure measuring 64 feet in diameter. The Steel Ball Hospital could reach up to 3 atmosphere absolute (atm). However, owing to the depressed financial status of the economy, the structure was dismantled for scrap in 1942.
Later, in the 1940’s, the military developed hyperbaric chambers to treat decompression sickness in deep-sea divers. HBOT was used during lung and heart surgery for the first time in 1950’s, which paved the path for the treatment to be used for carbon monoxide poisoning in the 1960’s. Since then HBOT has come a long way with scientists completing more than 10,000 case studies and clinical trials for the treatment many other health issues, successfully.
