Abstract:O4 and the dye T-1824 as labels, simultaneous injections were made into the right ventricle and into a peripheral vein, and cardiac output was calculated from the individual flowdilution curves. When a discrepancy beyond the range expected from the use of the two labels occurred, the output from the central injection was always the larger (approximately one-third of the observations, in a small series). This may be attributable to progressive blood loss from sampling, since delayed intraventricular injections … 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.
