Cardiac Output and Regional Blood Flow
Walshe, iMl.D., D.Sc., F R.S. Tenth Edition. (Pp. xii + 381; figs. 60. 35s.) Edinburgh and London: E. & S. Livin.gstone, 1963. THiE appeartanice of the tenth editioni of this textbook twenty-threc years since it was first published reflects its great pol)Ulllarity. The author alludes in the prefatce that its reviewers would probably not be drawn from the ranks of those to vholom the 1)ook is pa...
متن کاملEffects of aging on cardiac output, regional blood flow, and body composition in Fischer-344 rats.
The purpose of this study was to determine the effects of maturation and aging on cardiac output, the distribution of cardiac output, tissue blood flow (determined by using the radioactive-microsphere technique), and body composition in conscious juvenile (2-mo-old), adult (6-mo-old), and aged (24-mo-old) male Fischer-344 rats. Cardiac output was lower in juvenile rats (51 +/- 4 ml/min) than in...
متن کاملBlood Flow Measurement: The Cardiac Output and Vascular Resistance
The maintenance of blood flow commensurate with the metabolic needs of the body is a fundamental requirement of human life. In the absence of major disease of the vascular tree (e.g., arterial obstruction), the maintenance of appropriate blood flow to the body depends largely on the heart's ability to pump blood in the forward direction. The quantity of blood delivered to the systemic circulati...
متن کاملCardiac Output and Regional Blood Flow in Gills and Muscles after Exhaustive Exercise in Rainbow Trout (salmo Gajrdneri)
Rainbow trout (Salmo gairdneri) were electrically stimulated to exhausting activity and the changes in cardiac output and blood flow distribution to gills and systemic tissues resulting from the developing severe lactacidosis were repeatedly measured by the microsphere method (15 ̂ m). Determination of cardiac output by application of the Fick principle resulted in values not significantly diffe...
متن کاملRegional blood flow distribution in dog during induced hypotension and low cardiac output. Spontaneous breathing versus artificial ventilation.
Respiratory muscle blood flow and organ blood flow was studied in two groups of dogs with radioactively labeled microspheres to assess the influence of the working respiratory muscles on the regional distribution of blood flow when arterial pressure and cardiac output were lowered by pericardial tamponade. In one group (n = 6), the dogs were paralyzed and mechanically ventilated (Mv), while in ...
