Topic: Ebullism


  
  Explosive Decompression and Vacuum Exposure   (Site not responding. Last check: 2007-11-05)
This evolution of water vapor will cause marked swelling of the body to perhaps twice its normal volume unless it is restrained by a pressure suit.
Tam Czarnik, "Ebullism at 1 Million Feet: Surviving Rapid/Explosive Decompression" (unpublished review, 1999).
For more technical details, a paper discussing the medical effects of sudden vacuum exposure on a human, and discussing the emergency medical response to a decompression emergency, can be found in Dr. Tam Czarnik's paper Ebullism at 1 Million Feet.

 EBULLISM AT 1 MILLION FEET
This paper outlines the history of Man’s struggle with altitude, examines the known pathophysiology of Ebullism, explores the measures taken to improve survival in the Shuttle era, and investigates the state-of-the-art in treatment of rapid/explosive decompression.
While the conditions necessary for ebullism are present at an altitude of roughly 63,000 feet (referred to as the Armstrong Line), variations in the body’s temperature and pressure can allow this to occur as low as 55,000 feet (2); thus, the ‘line’ is perhaps better thought of as a band (3).
Cardiovascular Myocardial damage associated with ebullism is caused by stretching of the myocardium and anoxia (11).

The difference in the suit hydrostatic pressure and total pressure within the PTS, as measured by the helmet pressure sensor, is quantified as the residual pressure within the PTS 34, as shown in block 110.
As shown in block 112, pressure relief means 94 is activated under the combined conditions of +G.sub.Z or zero G.sub.Z acceleration component as tested under the decision block 114, and ambient pressures greater than the minimum threshold pressure, as shown in decision block 116.
Pressure relief means 94 is shut as shown in block 140 under combined conditions of -G.sub.Z acceleration component and the quantified residual pressure is equal to the minimum threshold pressure, as shown in decision block 142.

 Physiology Online
This piece of bad news is known as ebullism: the outer dimensions of the body may suddenly increase and unless the pressure around the body is rapidly normalised, unconsciousness follows within seconds and death soon afterwards.
Even if her oxygen supply was unaffected and she was protected from the cold, an astronaut who suffered a suit depressurisation on the surface of Mars would rapidly boil and die of ebullism.
A strength of the book is the author’s lucid exposition of the amazingly narrow limits which our basic physiological makeup can withstand and his emphasis on the many behavioural ways in which we strive to overcome these limits – a perfectly legitimate, and indeed vital, aspect of environmental physiology that has often been skated over.

This research focuses on the physiological effects of exposure to high altitude and provides the physiological basis for developing protective countermeasures.
Areas of interest include hypoxia, ebullism, positive pressure breathing, and decompression sickness (DCS).
Our goals are to mathematically model decompression, including inert gas diffusion and perfusion dynamics, gas phase separation, bubble growth dynamics, and statistically based approaches; and to develop predictive DCS risk assessment capability.
