Abstract:
A transportable hyperbaric chamber durable for 15 psi of pressure was used to treat a patient suffering from moderate acute mountain sickness at 3700 m above sea level. The symptoms were ameliorated a few minutes after pressurization in the chamber. After a 20-minute stay in the chamber, the patient was completely free of symptoms. Since the chamber can be inflated by using compressed air from a cylinder, no strenuous work was required of the operators. This transportable chamber seems to be useful for the treatment of high-altitude disorders at around 3000 m above sea level.
