Abstract Hypotension is one of the top three most frequent causes of cardiac arrests in the United States. One early intervention used in treating hypotension is placing patients in Trendelenburg position. The purpose of this research was to review information on the use of the Trendelenburg position or variations of it to determine whether this position has an impact on hemodynamic status‚ to describe historical practices of the Trendelenburg position‚ state the reasons and need for possible change

pressure results in decreased baroreceptor firing. The autonomic neurons within the medulla respond to this by increasing sympathetic outflow and decreasing parasympathetic (via the vagal nerve) outflow. Upon standing up‚ there is disinhibition of the sympathetic activity in the medulla so sympathetic activity coming from the rostral ventrolateral medulla increases. These autonomic changes trigger vasoconstriction‚ tachycardia and positive inotropy. These changes increase the cardiac output and therefore

ANATOMY AND PHYSIOLOGY OF THE HEART Anatomy: The heart and heart wall layers: The heart is located in the left side of the mediastinum; it consists of three muscle layers the Endocardium‚ myocardium‚ and epicardium. The epicardium is the outermost layer of the heart. The myocardium is the idle layer of and actual contracting muscle of the heart. The endocardium is the innermost layer and lines the inner chambers and heart valves. Pericardial sac: The pericardial sac encases and protects

Cardiovascular Case Study Atrial Septal Defect(ASD) is a very large problem concerning the heart in its overall function. When the heart‚ being the core of the cardiovascular system‚ has issues; it effects the rest of the body as a result. The core of the problem resides in the atrial septum. Normally the heart is divided into four separate chambers. But a person with atrial septal defect has an atrial septum that allows the blood from the left side of the heart back into the right side. This

When the heart is no longer able to pump enough blood to meet the demands of the body‚ it is referred to as heart failure or cardiac insufficiency. Congestive heart failure (CHF) is an abnormal condition characterized by circulatory congestion as a result of the heart’s inability to act as effective pump. Circulatory congestion and compensatory mechanisms occur. CHF may develop after MI‚ in response to prolonged hypertension‚ diabetes mellitus or in relation to valvular heart disease or inflammatory
