Function of the eustachian tubes in divers with a history of alternobaric vertigo.
The pure tone audiograms of a diverse group of U.S. Navy divers were examined across four major variables: (1) number of years of Navy diving experience, (2) previous noise exposure history, (3) previ...

Histopathology of the early stage of osteonecrosis in divers.
Voice fundamental frequency levels of divers in helium-oxygen speaking environments
human heliox speaking Voice speech intelligibility
2009/7/20
Divers under hyperbaric conditions experience a marked deterioration in speech intelligibility. Included among the possible features that contribute to speech degradation is change/distrotion of speak...
Visual evoked responses and EEG's of 16 divers breathing air at 7 ATA
human electrophysiological
2009/7/20
This study is an assessment of individual differences in electrophysiological response under diving conditions normally conducive to nitrogen narcosis. A group of 16 men made two dives each to approxi...
Dyspnea in divers at 49.5 ATA: mechanical,not chemical in origin
CO2 carbon dioxide human Dyspnea exercise respiratory
2009/7/20
Pulmonary function was studied in six divers living in a hyperbaric chamber at a pressure nearly fifty times normal (49.5 atmospheres absolute (ATA), equivalent to 488 m or 1600 ft seawater (fsw)). As...
Aseptic bone necrosis among U.S. Navy divers:survey of 934 nonrandomly selected personnel
Divers human Aseptic bone necrosis DCS
2009/7/20
Nine hundred thirty-four U.S. Navy divers were selected and surveyed radiographically using standard techniques developed for detecting aseptic bone necrosis (ABN). X rays were read by qualified radio...
Thermal measurements on divers in hyperbaric helium-oxygen environments
cold human Thermal measurement heliox
2009/7/17
During a series of three saturation dives to simulated depths of 1000, 1200, and 1400 fsw at the Ocean Simulation Facility, measurements were made to establish the rate of heat loss of unclad divers i...

2009/7/17
Twenty-four oxygen exposures lasting 80 to 271 min were performed by six immersed exercising subjects at 25 fsw (1.76 ATA) in both warm and cold water. Two types of exercise were performed, moderate w...
Alveolar Pco2 during rest and exercise in divers and non-divers breathing O2 at 1 ATA
human divers CO2 hypercapnia
2009/7/17
The extent of hypercapnia in oxygen-breathing subjects was investigated during rest and exercise (650 kpm/min). Divers, ex-divers, and non-divers were studied. Carbon dioxide retention was judged by e...
