Circulatory responses to venous air embolism and decompression sickness in dogs.
A 60-year-old male patient suddenly developed blindness, agitation, and disorientation 36 h after coronary bypass surgery. Onset of symptoms followed efforts to clear an air-filled radial artery cannu...
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 ...
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...
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...
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...
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...
The standard treatment for cerebral arterial gas embolism (CAGE) is an initial recompression to 6 atm abs on air for 30 min followed by oxygen breathing at 2.8 and 1.9 atm abs. It has been suggested t...
Recent studies have indicated that divers with a patent foramen ovale (PFO) are at risk of developing some forms of decompression sickness. Thus, the objective of the present study was to investigate ...
After an emergency ascent from very shallow depth, a diver suffered a triad of symptoms after bilateral barotrauma of the lungs: air embolism with subsequent paraparesis, pneumomediastinum, and bilate...
Treatment with the surface-active agent Pluronic F-68, shown to modulate the hemodynamic effects of venous air emboli (VAE) in dogs, may be useful for treatment of VAE in divers. We report on the effe...
Pulmonary air embolism induces the generation of vasoactive and cytotoxic substances leading to lung injury. In the present study we investigated, in isolated and perfused rat lungs, the involvement o...
Arterial gas embolism may occur as a consequence of lung rupture, decompression sickness, following operative procedures or as accidental infusion of gas during various diagnostic procedures. It can l...
I want to say something about micro air embolism. In Great Britain we have come to classify decompression sickness as being of two types Type 1, otherwise known as “the bends” in which there is pain...
The controversy over whether the novice scuba diver should be taught “free ascent” before receiving his diving certificate will always remain. Personally I feel that the diver should not attempt a f...
