Doppler bubble detection after hyperbaric exposure. 1996

Department of Anaesthetic Services, Royal Hobart Hospital, Tasmania, Australia.

A review of the literature on the use of transcutaneous Doppler to detect circulating venous bubbles occurring after hyperbaric exposure, with emphasis on the detection of bubbles occurring after relatively small decrements in pressure, is presented. The correlation between circulating bubbles and the occurrence of decompression illness is examined.

D001784	Blood Gas Analysis	Measurement of oxygen and carbon dioxide in the blood.	Analysis, Blood Gas,Analyses, Blood Gas,Blood Gas Analyses,Gas Analyses, Blood,Gas Analysis, Blood
D003665	Decompression Sickness	A condition occurring as a result of exposure to a rapid fall in ambient pressure. Gases, nitrogen in particular, come out of solution and form bubbles in body fluid and blood. These gas bubbles accumulate in joint spaces and the peripheral circulation impairing tissue oxygenation causing disorientation, severe pain, and potentially death.

D004242	Diving	An activity in which the organism plunges into water. It includes scuba and bell diving. Diving as natural behavior of animals goes here, as well as diving in decompression experiments with humans or animals.	Divings
D004618	Embolism, Air	Blocking of a blood vessel by air bubbles that enter the circulatory system, usually after TRAUMA; surgical procedures, or changes in atmospheric pressure.	Air Embolism,Embolism, Gas,Air Embolisms,Embolisms, Air,Embolisms, Gas,Gas Embolism,Gas Embolisms

D006931	Hyperbaric Oxygenation	The therapeutic intermittent administration of oxygen in a chamber at greater than sea-level atmospheric pressures (three atmospheres). It is considered effective treatment for air and gas embolisms, smoke inhalation, acute carbon monoxide poisoning, caisson disease, clostridial gangrene, etc. (From Segen, Dictionary of Modern Medicine, 1992). The list of treatment modalities includes stroke.

D018608	Ultrasonography, Doppler	Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.
