Biventricular Heart Failure

Heart disease encompasses a number of cardiac disorders, which collectively cause one third of all death in the United States. The normal functioning heart consistently pumps the oxygenated blood from the lungs to the left atrium of the heart by way of the pulmonary artery into the left ventricle where the oxygenated blood is pumped to the organs and body tissue. Deoxygenated blood then travels from the organs carrying carbon dioxide waste to the lungs for removal. The blood is then oxygenated as the carbon dioxide is released by the lungs and returns to the right atrium to then repeat the process (Kulick). A consistent blood flow, or heart rate ensures oxygen and nutrients reach the organs and body tissues at a speed which meets cell needs. …show more content…
Depending on the underlying illness and clinical situation, patients may have symptoms of left, right, or both types of heart failure called biventricular heart failure (Kulick). When heart failure occurs, the blood flow is restricted and therefore flows through the body and exchanging oxygen and carbon dioxide at a slower rate that increases blood pressure on arterial walls and valves. The heart chambers may react by enlarging to accommodate the increased pressure or become stiff and thickened to resist over exertion (WebMD). This helps to keep the blood moving at a necessary pace, but the heart and arterial walls may eventually weaken and become unable to pump as efficiently resulting in failure. Left heart failure occurs when the left ventricle can no longer pump blood to the body and fluids begin to back up and leak into the lungs. This causes shortness of breath, coughing, and wheezing. Right heart failure occurs when the right ventricle cannot effectively pump blood to the lungs. Blood and excess fluids may back up in the veins delivering blood to the heart. This back pressure in capillary blood vessels causes them to leak water into extracellular

Congestive Heart Failure Research Paper

...Congestive heart failure is defined as; “the heart does not pump as well as it should to meet the body’s oxygen demands.” (Congestive Heart Failure, John Hopkins Medicine) The heart has four chambers; two atria in the upper part of the heart, and two ventricles in the lower part of the heart. Ventricles transport blood to the organs and tissues. The atria receive blood after it circulates from the body. When another condition has damaged or weakened the heart, and the heart can’t maintain the normal demands of pumping blood to the rest of the body, heart failure occurs. The ventricles can become stiff and not fill properly in between beats. The ventricles can also stretch causing the heart to not be able to properly pump blood to the whole body. Increased heart rate usually occurs which is caused by increased sympathetic activity trying to maintain cardiac output. When the sympathetic stimulation is increased, it releases vasopressin (antidiuretic hormone), which then causes fluid retention in the kidneys. When this happens, one can have hypertension There...

Heart Failure

...Heart Failure Western Governors University Pathopharmacological Foundations for Advanced Nursing Practice Heart Failure It is estimated that about five million people in the United States are living with heart failure with an overwhelming number of 550,000 newly diagnosed cases each year, costing the nation roughly $32 billion dollars per year (Centers for Disease Control and Prevention, 2016). Heart failure is a complex, pathophysiological condition in which the ventricles of the heart is weakened and unable to pump effectively to meet the body’s needs for nutrients or has lost adequate filling capacity. Clinical presentations of heart failure depends on which ventricles have failed to pump blood adequately; left ventricular failure, also known as congestive heart failure (CHF) is more common than right ventricular failure (McCance & Huether, 2014). The most common symptoms of heart failure are shortness of breath, fatigue, and peripheral edema. HF is not a disease, but rather a manifestation of a diseased heart. Large number of disorders can lead to heart failure, and with the aging population and many surviving primary cardiac events, it is no surprise that the most common reason for hospitalization in patients older than 65 years old is heart failure (McClintock, Mose, & Smith, 2014). Heart failure has become a major public health problem because it is the only cardiac condition that continues to increase in prevalence (McClintock, Mose, & Smith, 2014)...

Annotated Bibliographies on Chf Readmissions

...Annotated Bibliographies Lisa Stevens Kaplan University Annotated Bibliographies Au, A., McAlister, F., Bakal, J., Ezekowitz, J., Kaul, P., & vanWalraven, C. (2012). Predicting the risk of unplanned readmission or death within 30 days of discharge after a heart failure hospitalization. American Heart Journal, 164(3). 365-372. Retrieved from: http://www.medscape.com/viewarticle/771215_print This article sought to find an appropriate model to predict the risk of unplanned heart failure readmissions. The primary outcome from chart reviews also included death of heart failure patients within 30 days of discharge. The study looked at Centers for Medicaid and Medicare Services (CMS) models and the LACE+ index, to mention two of many that looked at prediction ability. The LACE+ index is a model that looks at length of stay, acuity, the Charlson comorbidity score and age, to predict readmissions. They found that no one model was appropriate in predicting the 30-day readmission rates, although using a combination of the models was an improvement to that predictor. The authors are all physicians, PhDs, or have a Master’s degree- helping to establish credibility. The authors also make a statement as to the funding of the project and that they (the authors) were solely responsible for all data collection, design and submission approval writing for the project, also lending credibility to the study. The references used for this study were appropriate in age, of the 28; 13 were...

Treatment of Congestive Heart Failure

...Treatment of Congestive Heart Failure Nicole Martin North Island College Congestive Heart Failure Left heat failure, also known as congestive heart failure (CHF), is an imbalance in pump function in which the heart is failing and unable to do its work pumping enough blood to meet the needs of the body’s other organs. CHF is commonly thought of as a disease but in fact is a syndrome. A syndrome as defined by Mosby’s Dictionary, as “a complex of signs and symptoms resulting from a common cause or appearing in combination, to present a clinical picture of a disease or inherited abnormality” (Mosby, 2009). Heart failure usually develops slowly, often over years, as the heart gradually loses its pumping ability and works less efficiently. CHF affects individuals in different ways and to different degrees. It is usually a chronic disease and gradually becomes worse over time. Many people are not even aware of their condition until symptoms appear years after the heart began its decline. There are many causes, risk factors, and signs & symptoms that help determine if someone is at risk of developing CHF or already living with CHF. Nearly 500,000 Canadians are currently living with the condition, with 50,000 new cases diagnosed each year. With such high numbers of people diagnosed with CHF, I believe as a future nurse it will be beneficial to have a greater understanding as to how CHF develops, how it is treated, and how it is management. Etiology The etiology...

...Health Promotion in Nursing Care Rhea Acklin Grand Canyon University: NRS429V-Family Centered Health Promotion May 21, 2014 Instructor: Lori James Concepts of Health and Illness The most important goals of a nurse are to promote health, restore health, prevent illness, and to facilitate coping with illness, death and disability. Nurses maximize the health of patients of all ages, in many settings, and in both good health and illness. Health is not just the absence of illness, it is a state of mind, a patients maximum potential. The nurse’s knowledge of health and illness is very important in today’s focus on health promotion and advocacy (Taylor, Lillis, LeMone, & Lynn, 2011). There is a continuing trend toward care being provided in the home and community, moving away from hospital emergency rooms. A classic definition of health is a state of complete physical, mental, and social well being, not merely the absence of infirmity (World Health Organization, 1974). Of course, one’s family, culture, community, and society where one lives will influence personal perception of health and wellness. As nurses move forward into the 21st century, we must educate our patients in health promotion, how to prevent illnesses, seek treatment, and living healthier lives. Health Promotion Definition Health promotion today according to the World Health Organization (WHO) is “the process of enabling people to increase control over and improve their health.” (“Health Promotion...

Health and Social Care

...A toddler with Down syndrome Jeffrey was 14 months when I met him. He was born with Down syndrome and a congenital heart defect and had an open heart surgery when he was 6 months old. Jeffrey often got ear infections and had recently had a set of pressure equalizing (pe) ear tubes placed. Jeffrey was not walking and was not yet crawling. Children with Down syndrome do learn to crawl and walk and talk; it takes longer. Recent research and clinical experience suggests that, with regard to talking, these children benefit from early oral stimulation, oral motor awareness and multiple experiences with oral sensory stimulation. As soon as I met Jeffery, we began working on ` mouth wakeup` activities , stimulating his teeth, lips, gums , hard and soft palate, inside cheeks, and outside jaw muscles with a variety of toys and tools, including vibrators. We taught his parents to do the same at home. Another part of getting ready to talk is stimulating receptive language (language comprehension). In speech therapy visits we begin using short descriptive sentences to describe toys Jeffrey picked up (he was in a high chair initially). We dropped direct questions during these periods of indirect language stimulation and encouraged the parents to do the same. After two to three weeks, Jeffrey’s mother became adept at these techniques and began describing his activities as he did them so that he could hear them and associate the object he had with the words he heard. Her continuing work in this...
