Diving at diminished atmospheric pressure:air decompression tables for different altitudes
decompression human
2009/7/20
Fifty subjects performed 106 simulated dives at a final ambient pressure of 0.7 at (3000 m above sea level). One hundred and forty-three subjects performed 278 actual controlled dives at altitudes 900...
The response of fish blood cells,particularly thrombocytes,to decompression
decompression thrombocytes fish
2009/7/20
The effects of decompression on various blood-cell types in chinook salmon (Oncorhynchus tshawytscha) were investigated using a 4-liter hyperbaric chamber. Thrombocytes (platelets) were found to decre...
Gas phase separation during decompression in man:ultrasound monitoring
decompression human Doppler
2009/7/20
During two dive series, one to 132 fsw and one to 210 fsw, Doppler ultrasonic bubble detectors were used to monitor venous gas bubbles in divers during decompression and for 30 min thereafter. Various...

Alterations in long-bone regional blood flow associated with inadequate decompression in dogs.
Converting standard air decompression tables for no-stop diving from altitude or habitat
decompression human altitude
2009/7/20
Using the phase equilibration theory of Hills (1966), as modified by Hennessy and Hempleman (1977), it is possible to predict formulas for converting standard air decompression tables for no-stop divi...

2009/7/20
Relationship between pressure-reduction magnitude and stop time during stage decompression.
Studies were conducted to determine the susceptibility of the fetus to decompression sickness. Sheep were used because fetal and maternal circulation of sheep and human placentas are dynamically simil...
The kangaroo rat as a model for type I decompression sickness
decompression kangaroo rats goats
2009/7/20
This study involved 720 exposures of 70 kangaroo rats trapped in West Texas and showed that decompression-induced tail biting in this animal provides a good animal model for marginal limb bends in man...
This paper reports two cases involving divers who presented with painful hands and were treated for decompression sickness. Although treatment was successful, their symptoms and diving history suggest...
Decompression sickness in the goat:nature of brain and spinal cord lesions at 48 hours
decompression animal goat
2009/7/17
An investigation was undertaken to determine whether permanent damage to the central nervous system (CNS) is associated with transient decompression sickness in the goat. Twelve goats were compressed ...
Reduction of the incidence of decompression sickness in rats by smooth-muscle activating factor (SMAF)
decompression
2009/7/17
Normal rats were injected with a smooth-muscle activating factor (SMAF) to examine the dose-response relationshio of SMAF to the incidence of decompression sickness. After injections of saline or 1.0,...
Single-tissue modeling of decompression schedules
human decompression schedules Single-tissue
2009/7/17
This paper deals with the development of a single-tissue model that simulates the uptake and elimination of inert gases by the body of a diver. The model utilizes an effective single tissue with diffe...
The square-root principle in the calculation of one-stage (no-stop) decompression tables
human decompression calculation
2009/7/17
A square-root formulation, square-root time x excursion depth = k, developed at the Royal Navy Physiologic Laboratory (RNPL) predicts the safe duration of air excursions at 1 ATA for periods up to 6 h...
Use of oxygen for optimizing decompression
decompression oxygen toxicity oxygen window effective dose optimization animal rat
2009/7/17
For over 70 years, decompression has been facilitated by the use of elevated oxygen partial pressures. Oxygen has been administered even though little is known about the proper dosage or the way in wh...
