Function of the eustachian tubes in divers with a history of alternobaric vertigo.
Supportive evidence for altered platelet function in the dived rat
decompression animal rat platelet
2009/7/20
A study was conducted on the changes in platelet function and platelet count in the Sprague-Dawley rat induced by a bends-producing N2-O2 compression-decompression cycle. In those instances where mild...
Effects of increased O2-N2 pressure and breathing apparatus on respiratory function
human nitrox exercise breathing apparatus respiratory work of breathing
2009/7/20
The ventilatory response of four subjects was measured at rest and various intensities of exercise. Experiments were conducted in a dry pressure chamber (1) at 1 ATA and 4 ATA with the subjects breath...
Hydrostatic pressure and mammalian cardiac-pacemaker function
animal mice Guinea Pig dog Rabbits Rat pacemaker cardiac
2009/7/20
Hydrostatic pressure and mammalian cardiac-pacemaker function.
The squid giant synapse, which permits intracellular electrical measurements in a single, excitatory synapse, was exposed to helium pressures up to 204 atm. By stimulating presynaptically and recordin...
Eustachian tubal function during immersion
Ivarsson,A Lundgren,CEG Tjernstrom,O Uddman,R Ornhagen,HC
2009/7/20
The effects of head-out immersion on active and passive middle ear pressure equilibration were studied in three otologically normal scuba divers. Results were compared with the equilibration capacity ...
Analysis of frog neuromuscular function at hyperbaric pressures
animal frog neuromuscular function hyperbaric
2009/7/20
Nerve and muscle compound action potentials were measured in the frog sciatic nerve-gastrocnemius muscle preparation in a hyperbaric helium-air environment. Helium pressure to 69 ATA induced a reversi...
Calcium, magnesium, and phosphorus metabolism, and parathyroid-calcitonin function during prolonged exposure to elevated CO2 concentrations on submarines
submarine CO2 carbon dioxide
2009/7/17
Studies of calcium and phosphorus metabolism and acid-base balance were carried out on three Fleet Ballistic Missile (FBM) submarines during prolonged exposure to elevated concentrations of CO2. The a...
Human parotid alpha-amylase secretion as a function of chronic hyperbaric exposure
human alpha-amylase parotid gland
2009/7/17
Secretion of alpha-amylase by the human parotid gland increased significantly during eight days of hyperbaric exposure. This hyperactivity of the parotid gland presumably resulted from increased auton...
Effects of aspirin and dipyridamole on platelet function,hematology,and blood chemistry of saturation divers
decompression human drug aspirin platelet saturation
2009/7/17
Twenty-four young male divers were assigned randomly to 4 treatment groups: Group I received aspirin (325 mg) three times daily; II received dipyridamole (75 mg) three times daily; III received both d...
Adrenal function and the incidence of bends after decompression in mice: effect of adrenalectomy,corticosteroids, decompression intensity,and time of day
decompression adrenalectomy decompression intensity
2009/7/17
The adrenocortical endocrine subsystem has been demonstrated to enhance mammalian tolerance to harsh environmental conditions, including hypoxia and temperature extremes. In a series of factorial expe...
Pulmonary function in men with intermittent long-term exposure to hyperbaric oxygen
pulmonary hyperbaric human pulmonary function oxygen toxicity pulmonary intermittent exposure
2009/7/16
The effect of intermittent exposure to hyperbaric oxygen over a long period of time was evaluated in 65 subjects. Pulmonary ventilation and diffusion capacities were measured in 65 divers as well as i...
Equations for predicting diver regional skin temperatures as a function of mean skin temperature
human skin temperature diver vasoconstriction
2009/7/16
A series of linear algebraic equations have been derived from those of Kerslake (Flying Personnel Research Committee Memo 213, R.A.F. Institute of Aviation Medicine, 1964) for predicting the regional ...
Mechanical and physical factors in lung function during work in dense environments
hypoventilation pulmonary human
2009/7/15
The major effects of breathing dense gas during physical exercise in hyperbaric environments can be traced to high airway resistance during inspiration and expiration and especially to an increased te...
Relations of smoking and diving experience to pulmonary function among U.S. Navy divers
pulmonary smoking respiratory divers
2009/7/15
The relations of 4 pulmonary function parameters (measured from the forced expiratory spirogram) with diving experience (in years) and indices of cigarette smoking were examined in a group of 93 healt...
