Origin and time course of gas bubbles following rapid decompression in the hamster
decompression bubble animal hamster
2009/7/15
Because conflicting results have been obtained in studies of the hamster (Mesocricetus auratus) microcirculation following rapid decompression, we were interested in the origin of bubbles in the cheek...
Fetal and maternal bubbles detected noninvasively in sheep and goats following hyperbaric decompression
decompression animal sheep goat Fetal maternal Pregnancy bubble
2009/7/14
Pregnant sheep and goats were compressed with air to an equivalent depth of 49 msw (160 fsw) for bottom times ranging from 5 to 15 min. Maternal (precordial) and fetal (umbilical artery) circulation w...
Light and electron microscopic alterations in spinal cord myelin sheaths after decompression sickness
decompression sickness spinal cord myelin sheath animal dog
2009/7/14
Pathological examination of spinal cords from animals subjected to experimental decompression sickness (DCS) was undertaken in an attempt to explain the disparate response to treatment observed. Eight...
Two groups of divers (Group A and B) were compressed to 500 msw with trimix (n = 3) and heliox (n = 3). After 4 d at saturation depth Group A had a gas change to heliox. Both groups were followed with...
Effect of intravascular bubbles on perfusate flow and gas elimination rates following simulated decompression of a model tissue
human Health diving decompression
2009/7/14
This study deals with the monitoring of the elimination rates of gases from a porous cylindrical model of the human tissue during simulated single-stop decompression schedules. The data suggest the pr...
An effect of CO2 on the maximum safe direct decompression to 1 bar from oxygen-nitrogen saturation
saturation nitrogen human carbon dioxide
2009/7/14
An investigation into the maximum safe decompression step from oxygen nitrogen saturation to 1 bar was carried out with and without the presence of 0.02 bar carbon dioxide. The series, Islander 1, inv...
In vivo microbubble detection in decompression sickness using a second harmonic resonant bubble detector
decompression bubble detection dog animal
2009/7/14
A resonant bubble detection method based on a second harmonic technique has been used to monitor the femoral vascular system of dogs subjected to rapid decompression. For this study, the detector cons...
Intramuscular diclofenac sodium as adjuvant therapy for type I decompression sickness: a case report
decompression sickness human case report diclofenac sodium drug adjunctive therapy nonsteroidal anti-inflammatory drug NSAID
2009/7/14
The residual pain of type I decompression sickness (limb bends) occurring despite recompression therapy is due to an acute inflammatory reaction in the soft tissue around the joint. This case history ...
Pain-only decompression sickness affecting the orbicularis oculi
decompression hyperbaric human case report
2009/7/14
A case is reported of a diver who experienced the onset of pain in the left orbicularis oculi muscle approximately 20 min after surfacing from an experimental dive. A careful neurologic examination di...
This study identified the short- and long-term health effects among U.S. Navy divers (n = 328) who suffered decompression sickness (DCS) between January 1968 and December 1979 and compared their post-...
Seventy-six men and 7 women performed a 2nd dive in a pressure chamber under dry conditions after intervals at the surface of 10, 30, 90, or 120 min. Of these, 35 persons performed a 3rd dive after an...
Failure of heparin, superoxide dismutase, and catalase to protect against decompression sickness
Catron,PW Thomas,LB McDermott,JJ Holt,MA Harabin,AL Flynn,ET
2009/7/14
The effects of heparin (HEP), superoxide dismutase (SOD), and catalase (CAT) on the course of decompression sickness (DCS) were studied in anesthetized dogs (Canis familiaris). Animals were divided in...
Hormonal changes during decompression sickness
decompression decompression sickness hormone
2009/7/14
Changes in plasma hormone levels were studied in anesthetized dogs during decompression sickness. Hormone levels were measured in 4 groups: control (no dive, n = 9); air group (air dive, ventilated wi...
Effects of He-O2 breathing during experimental decompression sickness following air dives
decompression sickness pulmonary cardiac output heliox treatment air embolism animal dog
2009/7/14
The effects of ventilation with He-O2 during decompression sickness (DCS) and venous air embolism were studied. Fifteen anesthetized dogs were mechanically ventilated and subjected to repeated air div...
Decompression sickness in women divers
decompression sickness human female gender epidemiology
2009/7/14
The comparative incidence of DCS in women has been debated for years. Diving log data from the Naval Diving and Salvage Training Center (NDSTC), Panama City, FL, demonstrate that there is no increased...
