Hyperbaric oxygen therapy (HBOT) involves breathing oxygen in a high-pressure chamber. It increases the amount of oxygen in the body carried by the blood to supply injured tissues—patients who have the HBOT sessions breathe around 100% oxygen while inside the chamber. The dose of oxygen and recommended treatment depends on the person’s condition and how their body reacts to the sessions. In addition, HBOT can include risks and complications that doctors should inform their patients of before the treatment. HBOT treats several ailments ranging from infections to air bubbles in blood vessels. Treatments of different medical conditions can also include surgical or medicinal causes affecting a person’s body.
