Abstract:Exposure of restrained, unanesthetized dogs to a simulated altitude of 30,000 ft consistently resulted in respiratory alkalosis and marked hypokalemia. When alkalosis was prevented by increasing the pCO2 of inspired air during decompression, a smaller but statistically significant decrease in plasma potassium concentration still occurred. In comparison with previous studies, the hypokalemia observed in these restrained, unanesthetized dogs was greater than that found in either unrestrained or anesthetized dogs… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
