Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves the administration of oxygen at pressures greater than atmospheric pressure. This therapy is primarily utilized to address conditions such as decompression sickness, commonly known as 'the bends,' which occurs when a diver ascends too rapidly, leading to nitrogen bubbles forming in the bloodstream. Additionally, HBOT is indicated for air embolism, a condition where air bubbles enter the vascular system, as well as for the treatment of serious infections, severe anemia, and chronic wounds that are resistant to healing, particularly in patients with diabetes or those suffering from radiation injuries. During the procedure, patients are placed in a specialized chamber or room where the air pressure is elevated to levels that can be up to three times higher than normal atmospheric pressure. This increased pressure allows the lungs to absorb significantly more oxygen than would be possible under standard conditions. The enhanced oxygen levels in the bloodstream are crucial for restoring normal blood gas levels and promoting optimal tissue function and healing. Patients typically remain in the hyperbaric chamber for a duration of up to two hours, during which they are closely monitored by a physician or other qualified healthcare professional to assess their response to the therapy.
