Disorientation and vertigo, which develops in divers during descent, is objectively demonstrated with dysbaric electronystagmographic tracings. Middle ear barotrauma of descent is verified as a valid ...
Pressure equilibration of the middle ear during ascent
human ear barotrauma equalization ascent
2009/7/16
The capacity to equilibrate the middle ear with the ambient pressure depends on different factors. During descent when the clearing is active the technique is the most important factor. During ascent ...
Damage to the middle ear and the inner ear in underwater divers
decompression human ear barotrauma
2009/7/14
Postmortem human tissue from recently deceased divers was processed histologically to assess any inner and middle ear damage that could have resulted from the effects of pressure during diving. The fo...
Transcranial Doppler sonographic measurements of middle cerebral artery flow velocity during hyperbaric oxygen exposures
hyperbaric Transcranial Doppler seizure oxygen
2009/6/8
In the present study, experimental exposures to hyperbaric oxygen (HBO2) were performed (30-min exposure to 2.8 bar (280 kPa) pure oxygen). During all phases of the experiment, blood flow velocity in ...
Neutrophil sequestration and the effect of hyperbaric oxygen in a rat model of temporary middle cerebral artery occlusion
neutrophil model animal rat hyperbaric middle cerebral artery occlusion
2009/6/5
A rat model of reversible occlusion of the middle cerebral artery was developed to assess the role of neutrophils and prophylactic hyperbaric oxygen (HBO2) on cerebral injury. Blood flow to the ipsila...
TEMPORAL VARIATION IN MICROHABITAT USE BY A COASTAL MEGAFAUNAL ASSEMBLAGE (Middle Atlantic Bight, USA): An Experimental Approach
Scientific Diving megafauna microhabitat
2009/5/6
Many species of mobile megafauna are known to associate with small-scale topographic features (termed: microhabitats) on otherwise homogeneous substrates (e.g., small depressions, shells), Previous w...
