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…
In Nova Scotia, more than 100 people have a major amputation (limb loss) each year. This guide will help you get ready for your surgery by letting you know what to expect. This guide explains levels of lower limb amputation, who is on your health care team, what will happen before surgery, and what to expect after surgery. Information about coping with amputation, how to position yourself, care of your amputated leg and other leg and foot, getting around, and living at home is included. A list …
