Cerebral arterial air embolism: III. Cerebral blood flow after decompression from various pressure treatments

Autor: D R, Leitch, L J, Greenbaum, J M, Hallenbeck

Publikováno v: Undersea biomedical research. 11(3)

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 cortical evoked potentials (CEP), cerebral blood flow (CB

Cerebral arterial air embolism: IV. Failure to recover with treatment, and secondary deterioration

Autor: D R, Leitch, L J, Greenbaum, J M, Hallenbeck

Publikováno v: Undersea biomedical research. 11(3)

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 bar for 10 or 20 min; and air at 6 bar (165 ft) fo

Publikováno v: Stroke. 13(6)

Fifty-four dogs were exposed to multi-focal ischemia sufficient to maintain suppression of the P1--N1 amplitude of the cortical sensory-evoked response (CSER) for 60 minutes. Subsequently, the P1--N1 amplitude recovery of the CSER was followed for an

The effects of various gases on cortical and spinal somatosensory evoked potentials at pressures up to 10 bar

Autor: D R, Leitch, J M, Hallenbeck, L J, Greenbaum

Publikováno v: Aviation, space, and environmental medicine. 54(2)

The development of dog electrophysiological models for studying the treatment of cerebral arterial air embolism and spinal cord decompression sickness, required that the effects of the treatment gases on spinal and cortical somatosensory evoked poten

Cerebral arterial air embolism: II. Effect of pressure and time on cortical evoked potential recovery

Autor: D R, Leitch, L J, Greenbaum, J M, Hallenbeck

Publikováno v: Undersea biomedical research. 11(3)

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 at 2.8 bar. The study was confined to the recover

Cerebral arterial air embolism: I. Is there benefit in beginning HBO treatment at 6 bar?

Autor: D R, Leitch, L J, Greenbaum, J M, Hallenbeck

Publikováno v: Undersea biomedical research. 11(3)

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 assessed using median nerve somatosensory cortical
