Cerebral arterial air embolism: IV. Failure to recover with treatment, and secondary deterioration
decompression Cerebral arterial air embolism animal dog
2009/7/15
Cerebral arterial gas embolism was induced in 23 dogs that were then treated using one of six routines: no treatment; air at 2.8 bar (60 ft) for 2 min; air at 10 bar (300 ft) for 5 min; oxygen at 2.8 ...
Cerebral arterial air embolism:III.Cerebral blood flow after decompression from various pressure treatments
cortical evoked potentials Cerebral arterial air embolism Cerebral blood flow
2009/7/15
The effect of various combinations of time between 2 and 20 min and between pressures of 2.8 and 10 bar (60 and 300 ft) breathing air or oxygen at 2.8 bar (60 ft), on the continued recovery of cortica...
Cerebral arterial air embolism: II. Effect of pressure and time on cortical evoked potential recovery
submarine human Cerebral arterial air embolism cortical evoked potentials animal dog
2009/7/15
In a dog model of cerebral arterial gas embolism we studied the relative merits of several different treatments: air breathing at 2.8, 6, 8, and 10 bar (60, 165, 230, and 300 ft), and oxygen breathing...
Cerebral arterial air embolism: I. Is there benefit in beginning HBO treatment at 6 bar?
submarine human Cerebral arterial air embolism animal dog
2009/7/15
A method for studying treatment of cerebral arterial gas embolism in dogs is described. The model produces severe cortical dysfunction and cerebral blood flow deficits. The efficacy of treatment was a...
Direct ascent from shallow air saturation exposures
decompression human saturation air venous gas emboli
2009/7/14
Thirty-four healthy human subjects were exposed to shallow air saturation for 48 h [1.77 ATA (25.5 fsw) n = 19, 1.89 ATA (29.5 fsw) n = 15] and then decompressed to 1 ATA (0 fsw) in about 2 min. Sympt...

Effects of He-O2 breathing during experimental decompression sickness following air dives
decompression sickness pulmonary cardiac output heliox treatment air embolism animal dog
2009/7/14
The effects of ventilation with He-O2 during decompression sickness (DCS) and venous air embolism were studied. Fifteen anesthetized dogs were mechanically ventilated and subjected to repeated air div...
Heliox treatment for spinal decompression sickness following air dives
spinal decompression sickness air Heliox
2009/7/10
Enforced delay in treatment of spinal decompression sickness following scuba diving can result in paraplegia. Poor response from initial recompression to 18 m presents the clinician with a difficult m...
Air embolism may cause unrecognized ischemia of the gray-white junction
embolism AGE air brain gray white animal dog
2009/7/10
The border between the gray and white matter is defined by an abrupt change in average blood flow. This difference allows one to distinguish structure with [14C]iodoantipyrine autoradiography. The ang...
Bronchomotor response to cold air or helium-oxygen at normal and high ambient pressures
cold helium heliox hyperbaric human air lung animal rabbit
2009/7/10
Effects of inhalation of cold air or helium-oxygen mixture on lung resistance (RL) were studied in anesthetized and tracheotomized rabbits under normal ambient pressure and in human volunteers under n...
Manifestations and treatment of 793 cases of decompression sickness in a compressed air tunneling project in Hong Kong
decompression sickness air commercial
2009/7/10
In the largest compressed air tunneling contract for the construction of the Island Line of the Mass Transit Railway system in Hong Kong, 154,390 man-decompressions occurred, of which 142,140 were aft...
Air vs. He-O2 recompression treatment of decompression sickness in guinea pigs
decompression heliox model air animal guinea pigs
2009/7/10
Air vs. He-O2 (20.9% O2) recompression treatment was examined in a model of severe decompression sickness (DCS) using male albino guinea pigs (Cavia porcellus, 500-600 g). Following decompression to t...
Use of the maximum likelihood method in the analysis of chamber air dives
maximum likelihood method decompression model outcomes air chamber
2009/7/9
The method of maximum likelihood was used to evaluate the risk of decompression sickness (DCS) for selected chamber air dives. The parameters of two mathematical models for predicting DCS were optimiz...

decompression nitrogen pulmonary model embolism AGE air animal dog
2009/7/8
Venous air embolism occurs with decompression sickness as well as during a wide variety of surgical procedures in hospitalized patients. We developed a canine model to allow documentation and quantita...
Venous gas emboli and complement activation after deep repetitive air diving
