The overheated problem is the important issue in the operation of the hyperbaric oxygen chamber. A cooling system is applied to reduce the temperature of the hyperbaric oxygen chamber. We present the finite element method to build three types cooling system for solving the overheated phenomena in this problem. For achieving the better cooling way, this investigation considers different types of...

PURPOSE The purpose of this study was to examine the effects of hyperbaric oxygenation (HBO2) on sustained maximal muscle contraction. METHODS Fifty-two healthy volunteers participated in the study. Thirty-four experimental subjects breathing 100% oxygen at 253kPa (2.5ATA) in a multiplace hyperbaric chamber performed a maximal grip contraction for one minute (initial grip) followed by a 30-se...

Background: The Brain uses 20% of the total oxygen supply consumed by the entire body. Even though, <10% of the brain is active at any given time, it utilizes almost all the oxygen delivered. In order to perform complex tasks or more than one task (multitasking), the oxygen supply is shifted from one brain region to another, via blood perfusion modulation. The aim of the present study was to ev...

The use of titanium during hyperbaric oxygen therapy may pose a risk of fire. A fresh titanium surface in a high oxygen atmosphere can be a source of ignition. The clinical scenario may be a patient who accidentally breaks his titanium-framed glasses during a hyperbaric oxygen treatment in a monoplace chamber or using an oxygen hood. We recommend some safety precautions to be exercised until co...

INTRODUCTION The multiplace hyperbaric chamber provides a unique working environment for health-care personnel. The major foci of concern regarding staff health under these conditions have tended to be decompression sickness (DCS) and barotrauma. Incidences of DCS as high as 1.3% have been reported in hyperbaric attendants exposed to routine treatment tables. Occupational health risks of this m...

Kot J: Medical equipment for multiplace hyperbaric chambers. Part I: Devices for monitoring and cardiac support. Europ J Underwater Hyperbaric Med 2005, 6(4): 115-120. All medical devices introduced into the hyperbaric chamber should be of an appropriate design and fit for use in the hyperbaric environment and they should be certified by the manufacturer for hyperbaric conditions. However, unti...

PURPOSE This article was undertaken to present two cases of nonhealing ulcers that occurred after primary radiation therapy and local excision of suspected residual or recurrent anal carcinomas. Both patients responded favorably to hyperbaric chamber treatment. Review of the literature is discussed, including cause, clinical presentation, diagnosis, and options for management of radiation-relat...
