Myocardial perfusion imaging: Myocardial perfusion imaging (MPI) is a form of functional cardiac imaging, used for the diagnosis of ischemic heart disease. The underlying principle is that under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test. A cardiac specific radiopharmaceutical is administered.
PULMONARY OEDEMA Introduction Pulmonary oedema is defined as the build-up of fluid in the lungs usually due to Left ventricular failure and also a result of non-cardiogenic complications (Deepak, 2010). In this essay the three main causes of oedema will be explained, the pathophysiology, the intensity factors and the management in a pre-hospital setting. Causes of Pulmonary Oedema The two main causes of oedema are cardiogenic and non-cardiogenic. Cardiogenic pulmonary oedema is defined as the build-up of fluid in the lungs usually due to Heart failure.
Introduction to Atrial Fibrillation The most prevalent clinical arrhythmia is atrial fibrillation, which can be defined as irregular heart beats caused by uncoordinated activation of the atria. Atria are the two upper chambers of the heart. During atrial fibrillation, the cardiac muscles that make up the walls of these atrial chambers, receive disorganized activation signals. This causes them to fibrillate, which means rapid and irregular contractions. This results in inefficient pumping of blood from the atria into the ventricles, the lower two chambers.
The phenomenon of vein pulsation The venous retinal pulsation is occurring due to the blood pressure difference in the central retinal vein. The pressure difference occurs due to the condition of the systole and diastole pressure. The following are experimental studies carried out so far on physician experiment set-ups and existing theoretical models considered, wave surface with the Pulsations phenomena of collapsible vessels in the body deal.
A summary of this paper is that of the central line and the peripherally inserted central catheter line. They are both catheters and the both are inserted into an artery going straight to your heart. How these two lines differ are in the periods that they can be left in. This paper will also outline the risks of initiating and having one of these put in, and also the instructions on how to initiate one to begin with. The intention of this paper is to explain the uses of, and differences between PICC lines and Central lines, as they do apply to the patients in today’s ever expanding medical practices.
Varicose Veins Overview- A varicose vein (or varicose veins) is the abnormal dilation of the veins that appear swollen and that sometimes, when the varicose vein involves a superficial vein, can be observed through the skin. In our body the arteries carry oxygenated blood to the rest of the body from the heart, the veins, however, return the oxygen-poor blood to the heart because it is pushed towards the lungs and oxygenated. The arteries, which push oxygenated blood, they have a very effective muscle layer, which carries blood to the pressure or heart but not so the veins, which carry blood to low pressure.
Cystic Fibrosis Cystic fibrosis (CF) is a life-threatening inherited disease that causes an extreme increase of abnormal thick secretions, destruction of the lungs and digestive system, and frequent respiratory infections. In this paper it will go in depth about how one obtains the disease, the statistic of CF, the sign and symptoms, the method of diagnosis, and the treatment with a special interest in lung transplants. This paper will glance into a interesting case study of a CF patient post lung transplant that obtained candida albican pancreatitis. CF is a very serious medical condition that has a variety of symptoms, diagnostic tools, and treatments. CF was discovered in 1938 and since then there has been a great amount of information observed
Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Hannah Bunce Fayetteville Technical Community College Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Three of the most commonly occurring cardiac related events: angina, myocardial infarction, and cardiac arrest, are commonly confused. However, there is a huge difference between each of them. It is crucial to be informed of each of these cardiovascular emergencies and to be able to differentiate between them. As a medical professional it is also very important to know the appropriate care for each these cardiac related emergencies.
The first arrow goes through various serosal cavities. Mainly injuring the thoracic cavity, pleural cavity, parietal and visceral cavity, and the pericardial cavity. The two pleural cavities are found in the thoracic cavity which includes the lungs, heart, trachea, part of the esophagus, thymus gland, and thoracic duct. The heart will also be affected due to the location of the arrow. The heart is found in a small chamber called
The most common type of nosocomial infections are surgical wound infections, respiratory infections (such as ventilator-associated pneumonia), urogenital infections, as well as gastrointestinal infections. Wound and burn infections often nosocomial in nature. Hospital-acquired infections are a major source of morbidity, and even mortality to surgical patients. Immunocompromised patients, the elderly and young children are usually more susceptible than others. Nosocomial infections frequently occur after inhalation therapy, during use of indwelling catheters, transmission of communicable diseases between patients and healthcare workers, surgical procedures, injections, contamination of the health care environment (even the food or water provided at hospitals) or during use of chemotherapeutic or immunosuppressive drugs.
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 or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood.
