Managing Heart Failure Carla Vossen‚ SPN Kristin Madigan RN‚ BSN NURS 1300: Research Project South Central College November 23‚ 2009 Heart failure is a chronic and progressive syndrome‚ resulting from the inability of the heart muscle to pump with enough force to meet the metabolic demands of the body. (Buckler‚13) According to the Center for Disease Control; (CDC) there are approximately five million people in the United States that have heart failure. Approximately 550 thousand people

Scientific Basis Congestive Heart Failure is a disease in which the heart is unable to properly keep up with the amount of blood being sent to the heart. The heart muscle itself‚ in the case of heart failure‚ is unable to sufficiently pump the blood away from the heart and to the body to keep up with the incoming deoxygenated flow. This failure to pump blood can build up pressure and cause additional pumping resistance. The decreased cardiac output of heart failure causes the circulation to become

She has reported symptoms of dyspnea with exertions‚ orthopnea (evidenced by “sleeps on two pillows” at night)‚ fatigue (evidenced by “she often feels tired”) and edema (evidenced by “reports that ankles are often swollen in the evening”) alterations in urination (evidenced by “nocturia X 2 and reports she sometimes has a strong urge to void and does not always make it to the toilet in time”).

Systolic and Diastolic Heart Failure Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart’s pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium‚ then on to the left ventricle‚ which pumps it to the rest of the body. The left ventricle supplies most of the heart’s pumping power‚ so it’s larger than the other chambers and essential for normal function. (American Heart Association). In left-sided

body system there are homeostatic imbalances and one for the cardiac system is heart failure. Heart failure on the left side can happen in two ways‚ systolic heart failure and diastolic heart failure. A systolic heart failure is when the left ventricle cannot contract normally‚ which causes a decreased amount of oxygenated blood in the body because the heart cannot pump the blood efficiently. A diastolic heart failure is when the left ventricle cannot relax normally. This is because the heart muscle

EVERY SUCCESS STORY IS ALSO A STORY OF GREAT FAILURE Failure is the highway to success. Tom Watson Sr. said‚ "If you want to succeed‚ double your failure rate." If you study history‚ you will find that all stories of success are also stories of great failures. But people don’t see the failures. They only see one side of the picture and they say that person got lucky: "He must have been at the right place at the right time." Let me share someone’s life history with you. This was a man who

Background Heart failure (HF) is a condition in which the heart muscles lose its ability to pump sufficient blood to the body. It’s considered as one of the leading causes of death in the U.S with an estimated direct and indirect cost of $39 billion per year.1 Bioenergetics dysfunction is common in HF patients‚ which leads to energy starvation of the cardiac cells.2 Therefore‚ some medical providers encourage their patients to take ubiquinone‚ a lipid-soluble antioxidant‚ as an adjunct HF therapy

In this essay I will address market failure and how it may have occurred in a country of my choice‚ as well as how they have tried to correct the issues. Market Failure has many definitions‚ although I found that the one that best described it would have to be from the ‘Investopedia’. Of which it states that ‘in any given market‚ the quantity of a product demanded by consumers does not equate to the quantity supplied by suppliers’. This is due to the lack of certain economically factors that prevent
