This cannot be explained by the circulatory insufficiency alone; the increase of the oxygen consumption during those types of work is very slight, and these patients are still able to increase the cardiac minute volume more than would be necessary to cover the slightly increased demands for oxygen consumption and transportation.This question has some practical significance. There are several million cardiac patients with slight...Bibliography1. HEYMANSBOUCKAERTJOURDANNOWAKFARBER CIIFIGS: Survival and revival of nerve centers following acute anemia, Arch.
