Exercise conditioning reduces the risk of neurologic decompression illness in swine
exercise decompression animal pig model dry air Exercise conditioning Physical Conditioning
2009/6/12
During development of a pig model of neurologic decompression illness (DCI) we noted that treadmill-trained pigs seemed less likely to develop DCI than sedentary pigs. The phenomenon was formally inve...
Transesophageal echocardiographic study of decompression-induced venous gas emboli
decompression pulmonary dog animal venous gas emboli
2009/6/12
Transesophageal echocardiography was used to evaluate venous bubbles produced in nine anesthetized dogs following decompression from 2.84 bar after 120 min at pressure. In five dogs a pulsed Doppler c...
Diving at altitude requires different tables from those at sea level due to the reduction in surface ambient pressure. Several algorithms extrapolating sea-level diving experimental data have been pro...
Ascent rate, post-dive exercise, and decompression sickness in the rat
decompression exercise Ascent rate animal rat
2009/6/9
The effects of ascent rate and post-dive exercise on the incidence of decompression sickness (DCS) were investigated in six groups of 20 rats exposed for 2 h at a pressure equivalent to 240 feet of se...
Case report on a diver with type II decompression sickness and viral meningitis
decompression sickness viral meningitis case report
2009/6/9
A 33-yr-old man came to the emergency department with the chief complaint of a severe headache and decreased sensation in his right hand following a deep dive on scuba. Physical examination before rec...
Vasculitis masquerading as neurologic decompression illness
decompression sickness Vasculitis case report neurologic
2009/6/9
An adult male diver developed limb pains and peripheral neurologic signs following a series of dives. He was treated for acute neurologic decompression illness (DCI) and responded well, but subsequent...
Treatment of neurologic decompression accidents consists of various hyperbaric oxygen (HBO) protocols. To facilitate such comparisons between different protocols we developed a gravity score. A group ...
Reduction of decompression illness risk in pigs by use of non-linear ascent profiles
decompression helium heliox decompression illness model dry air chamber animal swine
2009/6/9
An established swine model of neurologic decompression illness (DCI) was adapted to investigate the influence of no-stop ascent profile shape on DCI risk after deep air and heliox dives. Pigs underwen...
Cardiopulmonary changes with moderate decompression in rats
decompression neutrophil pulmonary cardiovascular rat animal pulmonary edema
2009/6/9
Sprague-Dawley rats were compressed to 616 kPa (a) for 120 min then decompressed at 38 kPa/min to assess the cardiovascular and pulmonary responses to moderate decompression stress. In one series of e...
Relationship of the time course of venous gas bubbles to altitude decompression illness
decompression exercise venous gas emboli hypobaric pulmonary altitude outcomes bubble
2009/6/9
The correlation is low between the occurrence of gas bubbles in the pulmonary artery, called venous gas emboli (VGE), and subsequent decompression illness (DCI). The correlation improves when a "grade...
Development and interactions of two inert gas bubbles during decompression
model bubble inert gas
2009/6/8
A mathematical model has been developed to simulate the evolution of two inert gas bubbles in tissue. This is useful for understanding the dynamics of bubbles that presumably arise during decompressio...
Complement system response to decompression
decompression human Complement Activation biological markers
2009/6/8
A role for the activated complement system in the pathogenesis of decompression sickness has recently been suggested. In this study we aimed at evaluating the response of the complement system to deco...
Testing of hypotheses about altitude decompression sickness by statistical analyses
decompression model altitude
2009/6/8
This communication extends a statistical analysis of forced-descent decompression sickness at altitude in exercising subjects (J Appl Physiol 1994; 76:2726-2734) with a data subset having an additiona...
Breathing a mixture of inert gases: disproportionate diffusion into decompression bubbles
decompression bubbles diffusion
2009/6/8
To study the consequences of diving with gas mixtures, we simulated growth of decompression bubbles using an equation system that accounts for major determinants of bubble behavior. When breathing a m...
Probabilistic gas and bubble dynamics models of decompression sickness occurrence in air and nitrogen-oxygen diving
Gerth,WA Vann,RD
2009/6/8
Probabilistic models of the occurrence of decompression sickness (DCS) with instantaneous risk defined as the weighted sum of bubble volumes in each of three parallel-perfused gas exchange compartment...
