Overall cardiac output is the amount of blood that the heart pumps each minute. Congestive heart failure represents the end product of the many conditions that reduce the thrusting ability of the heart. Congestive heart failure is not a detailed disease but a illness that is measured by the inability of the heart to pump blood adequate with the metabolic needs of the body. Heart failure is accompanied by overcrowding of the body tissues. For instance, heart failure may be shown as an acute condition as in pulmonary edema or as a chronic condition as in congestive heart
Heart Failure is classified as a complex disease resulting from any functional or structural cardiac disorder impairing the competence of the ventricle to fill or expel blood (Porth, 2010). Heart failure is a condition where the heart is unable to pump enough blood to meet the demand of the body’s need. In contrast to a cardiac arrest, the heart does not stop to beat; it becomes weaker, usually over several months or years occurrence. The heart’s inability to pump adequate blood to fill the chambers. Subsequently, this provokes fluids to accumulate in the lungs and tissues, causing profusion.
Therefore the heart can't properly fill with blood during the resting period between each beat. As a result of left-sided heart failure, right-sided heart failure may occurs because of increased fluid pressure transferred back through the lungs and ultimately damaged the heart's right side.

The clinicians who are using line-powered electro physical agents are unaware of the dangers associated with electrical devices. The risk of electric shocks will increase. B. Line-Versus Battery-Powered Devices a line-powered device is that which is powered by building conventional current voltage for example in north America it is characterized by 60 hertz alternating current at 110-125v. A battery-powered device is that which is powered by battery source, characterized by 0 hertz at low voltage, such as 9v. C. Dangers Of Line-Powered Devices The flow of AC current in a body (i.e.
There are many causes of congestive heart failure. Coronary artery disease is one of the common disease of arteries that supply oxygen and blood to the heart and this causes decreased in the blood flow to the heart muscles which caused lack of oxygen
A magnetic bearing’s excessive heat can even be caused by having no lubrication. Although a magnetic bearing’s lubrication-free operation provides for a wear-free system, there is nothing that can now cool down the bearing. Heat buildup can create many serious problems such as destroying the magnetic bearings by breaking down the coil insulation and causing short circuits. Excessive heat can also cause the inability to carry the desired load in the application. Another important problem produced by magnetic bearings is limited fault protection.
When a fault happens, the fuse will melt and open the circuit; therefore, electricity will not go through the circuit. Although fuses are more sensitive than circuit breakers, fuses have to be replaced after being broken down. They only can be used once, while breakers can be worked again without changing them. Both of circuit breakers and fuses decrease the risks of using the electrical power (Wright & Newbery,
On the EKG this is shown by no clear P waves, only many small fibrillating waves, and no PR interval to measure. This results in a rapid and irregular heartbeat. On the other hand, ventricular fibrillation is much more serious and can cause sudden death if not treated by electrical defibrillation.
The pathophysiology of congestive heart failure is a viscous cycle. It starts out by some form of heart destruction or weakening of the heart muscle, usually caused by clogged arteries due to coronary artery disease or increased pressure on the left ventricular wall from chronic long term hypertension. This dwindling of the heart decreases stroke volume. The Medical Dictionary for Health Professionals and Nurses (2012) defines stroke volume as the volume pumped out of one ventricle of the heart in a single beat. So when stroke volume goes down, cardiac output also goes down.
This causes the blood flow to lessen due to not being able to flow thoroughly, which may cause the body to not receive proper blood flow. Myocardial infarction is the death of the cells in an area of the myocardium. This causes oxygen deficiency that is caused by a block in the blood supply also known as a heart attack. The left ventricle is the common site for MI, which is the chamber of the heart that works the most. This results in fibrotic scar formation and permanently impaired cardiac function (Zammaretti 2004).
