Modification of a standard bicycle ergometer for underwater use.
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...
Carbon dioxide response and breath-hold times in underwater hockey players
CO2 carbon dioxide breath hold dive
2009/7/14
Competitive underwater hockey play demands frequent and prolonged breath-hold dives. To see whether participants were physiologically adapted to breath-hold diving we studied the ventilatory response ...
Use of postmortem radiographs for the investigation of underwater and hyperbaric deaths
human postmortem radiography autopsy
2009/7/14
The use of postmortem radiographs as a useful adjunct in the investigation of hyperbaric and immersion deaths is discussed. This technique enables accurate identification of gas within cavities that o...
Effects of magnetic fields from underwater electrical cutting on in vitro corrosion of dental amalgam
model taste dental amalgam commercial magnetic field
2009/7/9
Metallic taste has been reported from divers working with underwater electric welding and cutting. An in vitro model was designed to simulate the intraoral situation of the divers with respect to the ...
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 ...
Static lung load and posture effects on pulmonary mechanics and comfort in underwater exercise
exercise pulmonary work of breathing position immersion
2009/7/8
Static lung load (SLL), or transrespiratory pressure gradient, imposed by underwater breathing apparatus can affect breathing comfort and mechanics, especially during exertion. We examined the effects...
Flow velocity in carotid artery in humans during immersions and underwater swimming
exercise immersion cardiac output underwater swimming
2009/6/12
Heart rate and flow velocity in the common carotid artery were examined on eight subjects in various underwater conditions. The heart rate decreased more markedly during whole-body immersion than duri...
Characterization and measurement of elastance with application to underwater breathing apparatus
underwater breathing apparatus elastance respiratory load
2009/6/12
The elastic loads inherent in underwater breathing apparatus (UBA) can affect diver performance. This work quantitatively examines elastance, its measurement by static tests, and its relationship to U...
Maximum sustained fin-kick thrust in underwater swimming
underwater swimming fin kick swim fin
2009/6/9
We examined the upper limit of a diver's fin-kick thrust force using a stationary-swimming ergometer. Heart rate, respiratory minute volume, oxygen uptake, and performance rate were measured in four m...
Responses to underwater exercise in scuba divers differing in trait anxiety
exercise CO2 carbon dioxide anxiety psychological panic
2009/6/8
Fifteen male scuba divers performed underwater leg ergometer exercise in an effort to determine if trait anxiety was related to their physiologic or perceptual responses. Psychologic assessment comple...
Circulating bubbles and breath-hold underwater fishing divers: a two-dimensional echocardiography and continuous wave Doppler study
decompression pulmonary breath-hold
2009/6/8
Since the 1960s,decompression illness after breath-hold diving has been widely debated. The aim of this study was to detect circulating bubbles after breath-hold diving in underwater fishing divers. W...
Simulating respiratory loads and tuning of closed-circuit underwater breathing apparatus
model human underwater breathing apparatus respiratory load rebreather closed circuit
2009/6/8
An experimental apparatus for simulating respiratory loads in closed-circuit underwater breathing systems comprises a partly submerged vertical tube having a dual path exit on the submerged end of the...
Influence of wet suit wear on anxiety responses to underwater exercise
wet suit exercise anxiety thermal protection
2009/6/8
The purpose of this investigation was to evaluate the effect of wearing a wet suit on selected psychological and physiologic variables. Certified divers (n = 13) finned underwater at 0.52 m/s for 20 m...
