Hemodynamic alterations with a reversed unidirectional intra-aortic balloon.
The hemodynamic effects of dual-chambered unidirectional balloon pumping in alternate directions were studied in 44 trials conducted on 8 dogs. Results indicate an increase in cardiac output in normal dogs with downstream pumping by unidirectional intra-aortic balloon, which may have important implications for the treatment of low output cardiac failure.
