Hemodynamics of Intestinal Circulation

Hemodynamics of intestinal circulation.

Clinical study of the cerebral hemodynamics during extracorporeal circulation.

The cerebral circulation was studied on 40 clinical cases which underwent open heart surgery under extracorporeal circulation by the low flow rate-hypothermic-hemodilution technique, by means of Kr85, opthalmoscope, blood gas and pH, and cerebral metabolism. Cerebral blood flow decreased to 65.2 per cent of the control value after the start of extracorporeal bypass, but recovered by the later p...

3: The physiology of hemodynamics: Metabolism and circulation

In order to better understand the intricacies of cerebral hemodynamics and the mechanisms behind neurovascular coupling, one must begin by understanding the many functions of blood and the circulatory system in large multicellular organisms such as ourselves. Therefore Chapter 3 begins by discussing basic mammalian physiology, with an emphasis on the vascular system. Blood rheology, vascular hy...

Hemodynamics, cerebral circulation, and oxygen saturation in Cheyne-Stokes respiration.

Because cardiovascular disorders and stroke may induce Cheyne-Stokes respiration, our purpose was to study the interaction among cerebral activity, cerebral circulation, blood pressure, and blood gases during Cheyne-Stokes respiration. Ten patients with heart failure or a previous stroke were investigated during Cheyne-Stokes respiration with recordings of daytime polysomnography, cerebral bloo...

Regional hemodynamics during postexercise hypotension. II. Cutaneous circulation.

After an acute bout of exercise, there is an unexplained elevation in systemic vascular conductance that is not completely offset by an increase in cardiac output, resulting in a postexercise hypotension. The contributions of the splanchnic and renal circulations are examined in a companion paper (Pricher MP, Holowatz LA, Williams JT, Lockwood JM, and Halliwill JR. J Appl Physiol 97: 2065-2070,...
