The Use of Proton Pump Inhibitors - Research is showing that the numbers of proton pump inhibitors (PPIs) are being over prescribed during hospital stays and subsequently on discharge. There are studies published that show there are opportunities for substantial cost savings in relation to PPI prescription if there were some clinical guidelines used across the board nationwide. In addition to the costs, there are also risks for devastating side effects of continued use. There is a need to have a more defined reason for the administration and continuation of PPI’s....   [tags: step therapy, prescription, hospitals]

Cardiovascular Disease and Aging - The function of the heart is to pump blood, rich in oxygen, throughout the entire body. Deoxygenated blood enters the right atrium through two veins called the superior and inferior vena cava. As the right atrium contracts, blood is pumped through the tricuspid valve to the right ventricle. When the right ventricle becomes full the tricuspid valve will close and deoxygenated blood will be pumped from the right ventricle through the pulmonary valve to the pulmonary artery, then to the lungs to become oxygenated....   [tags: heart, oxygen, blood, pump, value, vessels] 552 words

Heart Rate: How can it Affect You? - The heart is one of the most important organs in your body. Although it is small, it pumps about five quarts of blood, carrying oxygen, to each of your muscles in your body about one thousand times per day. The heart is a muscle controlled by electrical signals produced by the sinoatrial node which is part of the cardiac conduction system. Like all things, malfunctions happen through accidents, defects, and just plain neglect. When things go wrong with the heart, it can very easily become fatal, so it is very important to keep your heart healthy and know your heart rate, along with the factors that go with it....   [tags: pump, blood, health]
