We developed an experimental method which enabled continuous determination of the circulatory blood volume, when the blood volume was subjected to alterations. The blood volume was modified by a servo system to control transfer of the blood between an external reservoir and the cardiovascular system. Possible application of our method to the analysis of circulatory responses to blood volume cha...

This epidemiological and exploratory-descriptive study aimed to identify the socioeconomic and demographic features, as well as the health and disease condition of elderly people from a Family Health Program in Porto Alegre, Brazil, with the purpose of contributing to the planning of health actions for this population. Data from 98 elderly people were collected through a home survey by means of...

A new tool for real-time characterization of both systemic and local circulatory hemodynamics has been developed. Given two peripheral circulatory waveform measurements this new signalprocessing algorithm generates two low order models that represent the distinct branch dynamic behavior associated with the measured circulatory signals. The framework for this methodology is based on a multi-chan...

Abstract Background Congenital malformations (CMs) were the second cause of death in infants under age 1 year North America and Europe 2017, behind perinatal causes.Of CMs, those circulatory system (MCSs) most lethal. Studies Brazil, England have reported higher mortality from MCS presence prematurity, non-white skin color newborn, asphyxia, low birthweigth, advanced maternal age, education lev...

A L T H O U G H tilt table procedures have been used extensively in the study of the circulatory system, most studies have been with subjects in the feet-down position. 1,2 The tilt table provides a means of studying the influence of g force upon the circulatory system. When an individual is strapped to the tilt table, feet down, in the vertical position r he is exposed to + 1 g. When tilted to...
