title: The Bcg for measuring cardiac output in a California Gray Whale.
abstract: Resting cardiac output can be predicted reasonably accurately from body mass in man and other mammals. We measured the stroke volume of a 4,500-kg whale and found that Iberall's formula holds true even when body mass is very large. In addition, the Bcg acceleration trace and cardiac indices were remarkably similar to those of 20-gram and 70-kg mammals, mouse and man.
