چکیده

bstract-Cardiovascular response to running exercise was studied ith a simple pulsatile cardiovascular model. Published perimental data during graded exercise were used to tune the odel parameters. Study results show that cardiac output is odulated by rhythmic muscle contractions during running. It cillates when step rate and heart rate are not synchronised but abilises when they are synchronised. A maximum cardiac output n be achieved by synchronising step rate with heart rate at an timal phase delay. eywords – Cardiovascular model, heart rate, step rate, running

A Wireless Electronic Esophageal Stethoscope for Continuous Monitoring of Cardiovascular and Respiratory Systems during Anaesthesia

Background: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. In addition, the stethoscope is not applicable for continues monitoring, and it is u...

Comparison of Ground Reaction Force Components during Running with Running Shoes and Control Shoes in Individuals with Genu Varum

Introduction: Running poses an essential role in maintaining cardiovascular health. However, it has been demonstrated that 2.5 to 38 injuries per 1,000 hours of running can occur. The purpose of this study was to investigate ground reaction forces components during running with running shoes compared to control shoes in individuals with genu varum. Methods: This study was laboratory and semi-e...

Application of a Direct Model Reference Adaptive Controller (DMRAC) in a Nonlinear Cardiovascular Model

The objective of this study is to design a robust direct model reference adaptive controller (DMRAC) for a nonlinear cardiovascular model over a range of plant parameters representing a variety of physical conditions. The direct adaptive controllers used in thisd study require the plant to be almost strictly positive real (ASPR) that is, for a plant to be controlled there must exist a feedback ...
