The Use of Hyperbaric Oxygen Therapy in Ophthalmic Practice
Ahmed Zaki Wahba Ismail;
Abstract
In the early 1900, Cunningham developed a cylindrical hyperbaric chamber approximately 3 meters in diameter by 27 meters in length, which could be used to treat many conditions.
In March 2000, the American Board of Medical Specialties approved undersea and hyperbaric medicine as a subspecialty of both emergency medicine and preventive medicine.
The physics behind HBOT lies within the ideal gas laws. Boyle’s law (p1.v1 = p2.v2) i.e. gas pressure is inversely proportional to its volume.
Henry’s law states that the amount of gas dissolved in a liquid is equal to the partial pressure of the gas exerted on the surface of the liquid. By increasing the atmospheric pressure in the chamber, more oxygen can be dissolved into the plasma
Mechanisms of action of HBOT are hyper oxygenation vasoconstriction, angiogenesis, fibroblast proliferation and collagen synthesis, leukocyte oxidative killing،reduction of intravascular leukocyte adherence reduction of lipid peroxidation and antibiotic synergy.
Oxygen chambers are either Multiplace chamber (for multiple patients and inside observer who monitors the patients and assists with equipment manipulation or emergencies) or Monoplace chamber (for one person at a time and employees tend to the patient from outside of the chamber).
