Magnetic field effects on dental amalgam in divers welding and cutting electrically underwater
model Magnetic taste dental amalgam commercial
2009/7/9
Divers have for some years been complaining about a metallic taste in the mouth while electrically welding and cutting underwater. This paper reports on results from an assessment of this problem. It ...
Nutritional status of land-based U.S. Navy divers
cold Nutritional American Heart Association guideline
2009/7/9
The nutritional status of 16 male, land-based U.S. Navy divers was assessed to collect baseline information for a cold water dive series. Diet records, blood samples, and 24-h urine collections were o...
HPNS effects among 18 divers during compression to 360 msw on heliox
cognitive high pressure neurologic syndrome compression heliox
2009/7/9
Heliox compression deeper than 16 ATA can lead to EEG changes associated with confusion and somnolence. In man the symptoms termed the high pressure neurologic syndrome (HPNS) can also include increas...
Behavioral effects of increased CO2 load in divers
CO2 retention carbon dioxide air performance
2009/7/9
The behavioral effects of elevated PACO2 were examined to clarify risks due to CO2 retention in diving. In two separate laboratory studies, experienced divers breathed 6% CO2 mixtures under normobaric...
Analysis of neurologic symptoms in deep diving: implications for selection of divers
decompression helium heliox neurologic
2009/7/9
Eighteen professional divers (age range 24-33 yr, mean 28.3) participated in one simulated dive to 360 meters of seawater (msw) in a helium-oxygen (heliox) atmosphere with equal compression and decomp...
A portable ECG recorder was used during breath-hold dives at sea by 3 elite divers to 65 and 45 m. ECG was also recorded during nonimmersed maximal breath holds in the divers and 8 control subjects. H...
Case control study of cerebral perfusion deficits in divers using 99Tcm hexamethylpropylene amine oxime
decompression cerebral perfusion
2009/7/8
In a preliminary report, Adkisson et al. (Lancet 1989; 2:119-121) used 99Tcm-hexamethylpropylene amine oxime (HMPAO) single photon emission computed tomography (SPECT) to provide evidence for cerebral...
Daily diving pattern of Korean and Japanese breath-hold divers (AMA)
cold breath hold gender
2009/7/8
Daily diving patterns and thoracic skin and sea-water temperatures were recorded during the entire work shift of Korean female unassisted (cachido) and Japanese male unassisted and partly assisted (fu...
Characteristics of the response to exercise in professional saturation divers
saturation CO2 carbon dioxide exercise pulmonary screening
2009/7/8
Exercise testing with measurements of expired minute ventilation (VE), oxygen uptake (VO2), and carbon dioxide elimination (VCO2) was done in 63 professional saturation divers, in the screening progra...
Susceptibility of divers in open water to motion sickness
nitrogen dry nausea motion sickness
2009/7/8
Several aspects of the environment of divers should increase their susceptibility to motion sickness: a) sensory conflicts, b) body fluid redistribution, and c) nitrogen narcosis. We tested motion sic...
Physiologically and subjectively acceptable breathing resistance in divers' breathing gear
hyperbaric chamber breathing resistance exercise equipment
2009/7/8
To determine acceptable levels of breathing resistance in divers' gear, 6 subjects were exposed to varying levels of breathing resistance under demanding and realistic conditions. The immersed air-bre...
Muscle swelling in divers may represent a previously unreported form of decompression sickness. It shows marked, brawny swelling of skeletal muscle which clinically most suggests muscular lymphedema i...
Pupil cycle time in the long-term neurologic assessment of divers
saturation decompression cognitive neurologic
2009/6/12
Pupil cycle time (PCT) is an ophthalmologic technique that measures the speed of nerve conduction throughout the pupil reflex arc. An abnormally prolonged measurement may reveal subtle lesions to the ...
A histopathologic and immunocytochemical study of the spinal cord in amateur and professional divers
saturation decompression human
2009/6/12
To clarify the influence of diving activity on the central nervous system, we studied 10 amateur and 10 professional deceased divers with emphasis on the presence of subacute or chronic pathologic cha...
