Species differences in decompression
decompression statistical evaluation animal literature review method
2009/7/17
In an effort to bring together the diverse laboratory-animal decompression studies, a literature review and statistical evaluation were undertaken. Although 22 different species that had been used in ...
Bubble production in agarose gels subjected to different decompression schedules
agarose gel bubble decompression
2009/7/17
The relative effectiveness of seven different (military, commercial, and experimental) decompression schedules in reducing bubble formation within aqueous gels has been evaluated quantitatively under ...
Ultrasonic imaging system for the study of decompression-induced gas bubbles
Ultrasonic Imaging equipment bubble
2009/7/17
An high-resolution pulse echo ultrasonic imaging system has been developed to study decompression-induced gas bubbles. It was considered necessary that the system be capable of detecting gas bubbles w...
Correlation between decompression sickness and circulating bubbles in 232 divers
decompression sickness human bubbles
2009/7/17
Doppler monitoring examinations were carried out during 67 simulated helium-oxygen dives in the pressure chambers of the Centre d'Etudes Hyperbares (CEH) COMEX Marseille, and involved a total of 232 C...
Diffusion and nucleation of gas in gel and some implications for the development of decompression procedures
decompression human nucleation Gelatin Diffusion
2009/7/17
Attention is directed to certain incongruities among accepted diving procedures in order to emphasize the need for a more complete understanding of the interactions between the factors involved in div...
Adrenal function and the incidence of bends after decompression in mice: effect of adrenalectomy,corticosteroids, decompression intensity,and time of day
decompression adrenalectomy decompression intensity
2009/7/17
The adrenocortical endocrine subsystem has been demonstrated to enhance mammalian tolerance to harsh environmental conditions, including hypoxia and temperature extremes. In a series of factorial expe...
Amelioration of decompression sickness in mice by pretreatment with cyproheptadine
decompression animal mice drug
2009/7/17
Substances that stimulate smooth muscle have been previously implicated in the pathogenesis of decompression sickness. This concept was strongly supported by the demonstration that compounds that comb...
Separation of basic parameters of decompression using fingerling salmon
argon decompression nitrogen neon
2009/7/17
The experimental limitations inherent in use of air-breathing vertebrates for studies of decompression are chiefly due to the difficulty in estimating supersaturation levels associated with both sympt...
Nature and treatment of decompression sickness occurring after deep excursion dives
human case report decompression sickness saturation excursion
2009/7/17
During Predictive Studies IV (PS IV), the fourth in a series of collaborative undersea investigations, plans were made for excursion compressions to 1200 and 1600 feet of sea water (fsw) from saturati...
Venous gas bubble production following cold stress during a no-decompression dive
human thermal bubble exercise
2009/7/16
The effect of cold stress on venous gas bubble production was studied using Doppler ultrasonic monitoring. Ten subjects participated in four exposure regimes carried out at 78 fsw on an underwater pla...
Size distribution of intravascular air emboli produced by decompression
decompression bubbles diameters lungs organ
2009/7/16
Intravascular bubbles formed by decompression have been measured in 7 living dogs to give 14 different determinations of size distribution. Larger bubbles were estimated by the terminal rise velocity ...
Ruthenium red staining of blood-bubble interface in acute decompression sickness in rat
decompression sickness blood bubble interface animal rat
2009/7/16
The ultrastructure of the blood-bubble interface has been studied in rats decompressed experimentally. Subsequent to staining with ruthenium red there was detected by electron microscopy a continuous ...
Application of bubble formation model to decompression sickness in fingerling salmon
decompression sickness human cavitation model gas nuclei fingerling salmon animal
2009/7/16
Recently a new cavitation model has been proposed in which bubble formation in aqueous media in initiated by spherical gas nuclei stabilized by surface-active membranes of varying gas permeability. In...
Six experimental investigations of various mechanical aspects of the spinal cord are described relevant to its injury by gas deposited from solution by decompression. These show appreciable resistance...
Evaluation of different decompression schedules by an agarose gel bubble technique
human agar gel decompression schedule bubble evaluation
2009/7/16
It is well known that diving decompression schedules vary according to country and that Navy schedules are often different from civilian ones. Furthermore, it is difficult to compare them effectively,...
