This is the only up-to-date systematic review of normal human response to upright posture and lower body negative pressure (LBNP). It analyzes the key factors that influence postural tolerance, such as physical fitness, weightlessness, age, and sex. It also provides extensive details on the circulatory changes that have occurred during U.S. and Soviet manned space flights. The text is brilliantly illustrated with diagrams, tables, and comments on circulatory methods. Readers will discover some information which has never before been published. This one-of-a-kind volume also reviews the diagnosis and treatment of orthostatic hypotension-an extremely common orthostatic disorder. Circulatory Response to the Upright Posture is the first available literature since 1982 of human physiological and pathophysiological aspects of postural tolerance. A wide variety of readers will find this title interesting and of value. Circulatory physiologists, cardiologists, and everyone with an interest in exercise physiology, aging, space physiology, and environmental physiology will especially benefit from this writing.

Young women are known to exhibit a greater incidence of orthostatic hypotension than men. The exact mechanisms for this are unclear and it has been proposed to be related to cardiac filling, peripheral resistance, and/or regional blood pooling. The sexually dimorphic effects of lower body negative pressure (LBNP) or upright posture were investigated throughout this study.

Background: Orthostatic hypotension (OH) refers to a significant decline in blood pressure that occurs upon assuming an upright posture and represents an intrinsic risk factor for falls in older adults. Methods: Beat-to-beat blood pressure and cerebral blood flow velocity responses were assessed during a passive seated orthostatic stress test (PSOST). In healthy controls, PSOST responses were compared to head up tilt (the 'gold-standard'). In a cohort of long-term care residents, data from PSOST were compared to falling history.Results: Hemodynamic and cerebrovascular responses were similar between head up tilt and PSOST in healthy controls, except for the delayed systolic blood pressure decline. Older adult fallers had greater delayed systolic blood pressure declines and maximum cerebral blood flow velocity declines compared to non-fallers.Conclusions: PSOST may be a good surrogate for head up tilt in some population groups. We identified novel cardiovascular differences for falling risk in long-term care residents.

Standard techniques of cardiac catherization and the indicator dilutin method for cardiac output were made in the young chimpanzee. Determinations of pressure in the pulmonary and systemic circulation and cardiac output were obtained with the animals at rest in the supine position and during the altered hemodynamic states accompany ing psychomotor arousal, hemorrhage and head-up tilt. All studies were performed without pharmacologic preparation of the animals. Comparison of the circulation of the chimpanzee with that in the human demonstrated a tendency for heart rate, Cardiac output and arterial pressure to be higher while pressures in the pulmonary circulation were in a range similar to that in te human of comparable size and age. These observations demonstrate that the chimpanzee is a convenient laboratory primate for hemodynamic studies in whom circulatory responses can be observed with techniques commonly employed in the human.

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 flow. New and expanded chapters cover the arterial pulse, circulation in the upright posture, microcirculation and functional heart morphology. Heart and Circulation offers a new perspective for deeper understanding of the human cardiovascular system. It is therefore a thought-provoking resource for cardiologists, cardiac surgeons and trainees interested in models of human circulation.
