The field of pediatric mechanical circulatory support has undergone a significant evolution with the advent of devices designed for children and the implementation of new strategies for deployment. With the ongoing shortage of organs the demand for new devices specifically designed for children will only increase. This review discusses the evolution of mechanical circulatory support, available ...

BACKGROUND The circulatory system diseases (CAD), one of the most important current health problems, have started to show a declining trend in mortality in several countries, although they are still proportionally the number one regarding the statistics of morbimortality. OBJECTIVE To analyze the mortality trend due to CAD in Brazilian capital cities, during the period of 1950 to 2000. METH...

The human body requires a complex circulatory system to supply nutrients to, and to remove metabolic waste products from, its tissues. Given this primary purpose, circulatory function is closely related to the hemodynamic characteristics of blood vessels. This includes not only macroscale fluid dynamics, but also mass transfer in the microvasculature. Many experimental and clinical studies have...

Developing systems thinking skills in school can provide useful tools to deal with a vast amount of medical and health information that may help learners in decision making in their future lives as citizen. Thus, there is a need to develop effective tools that will allow learners to analyze biological systems and organize their knowledge. Here, we examine junior high school students' systems th...

The article presents the results of assessing functional state autonomic nervous system in patients with circulatory disorders vertebrobasilar system. It has been established that addition neuro-reflex diagnostic methods (dynamic segmental diagnostics and manual examination) improves assessment sympathetic allows monitoring effectiveness etiopathogenetic therapy. application reflexotherapy biod...

BACKGROUND In acute respiratory distress syndrome (ARDS), gas exchange and respiratory system mechanics (compliance) are severely impaired. Besides ventilatory parameters, the degree of respiratory abnormality can be influenced by the circulatory state. This study investigated the influence of acute hypovolemia on the respiratory system. METHODS We performed a secondary analysis of a previous...

Antepartum hemorrhage is one of the leading causes of mortality around the world. It can result in hypovolemic shock leading to circulatory arrest during pregnancy. A well-planned strategy is required for its management in all hospitals. To deliver a woman in this situation is a dilemma, which needs very prompt decision and a swift speedy action. Not only the woman's life is in danger, the fetu...

Paresthesiaa of the kind commonly known as "pins and needles" occur spontaneously in a variety of conditions. They may be produced deliberately by mechanical or electrical stimulation of a nerve, by overbreathing, or by cutting off the circulation to a limb and then releasing it. The present study is mainly concerned with the parvsthesixc which follow a period of circulatory arrest in a limb, a...
