After cardiac surgery, there are lots of things you can do to speed up your recovery such as: being as fit as possible before your surgery, lowering the stress of surgery on your body, and getting up and moving soon after your surgery. This pamphlet explains how to do these things. Topics include: eating well, staying active, doing your exercises, practicing post-surgery restrictions, getting ready for surgery, steps to help your recovery while in hospital, and what to expect after you leave th…
This extensively revised second edition traces the development of the basic concepts in cardiovascular physiology in light of the accumulated experimental and clinical evidence. It considers the early embryonic circulation, where blood circulation suggests the existence of a motive force, tightly coupled to the metabolic demands of the tissues. It proposes that rather than being an organ of propulsion, the heart, serves as an organ of control, generating pressure by rhythmically impeding blood …
What drives the circulation? In this comprehensive review of existing circulation models, the conventional view that the heart is a pressure-propulsion pump is challenged. The existing models fail to explain an increasing number of observed circulatory phenomena. A unifying circulation model is proposed in which the blood, responding to metabolic demands of the tissues, is the primary regulator of cardiac output. This new model arises from accumulated clinical and experimental evidence. The hea…
