Nitroglycerin Essays

Italian chemist, in 1847, nitroglycerin initially attracted scientific interest for its explosive properties.* Now famous for the prize that bears his name, Alfred Nobel extended Sobrero’s work, utilizing nitroglycerin in the development of the powerful explosive dynamite. Coincidentally, Nobel, who suffered from angina pectoris (AP) later in his life, was prescribed nitroglycerin to alleviate his symptoms: “…isn’t it the irony of fate that I have been prescribed NG1 [nitroglycerin] to be taken internally

The paramedics arrive and notice a bottle of nitroglycerin on the table. The patient states he has angina and is to take the medication as needed for chest pain. He took one pill an hour ago and a second pill 10 minutes prior to calling 911. Prior to this evening’s chest pain, he ate at a buffet and consumed 4 whiskey drinks. His ECG is not indicative of a myocardial infarction. What are the clues that helped the paramedic determine why the nitroglycerin did not alleviate the man’s angina? The paramedics

The rapid expansion causes the liquid nitroglycerin to combust. The decomposition is caused by a supersonic shock wave which passes through the material, and instantly destroys the molecules in it. The quick destruction of the molecules is called a detonation, and the rapid expansion of gas which is the cause of the large blast. The decomposition of the nitroglycerin can be caused by heat, or movement, it is most often lit on

motivated alfred to develop a safer explosive so that he could help prevent anything like this from ever happening again. His brother had been working in a factory which had been producing Nitroglycerin, many were killed and harmed in the incident, and the explosion left the city to ban the production of Nitroglycerin in the

The nursing staff could wean the patients’ nitroglycerin drip as well as morphine and versed (drugs used for pain management and a sedative), overnight. After his initial morning assessment by respiratory, nursing, and his physician, respiratory was given the order to assess weaning parameters and perform

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

and filled them with black powder to clear the way (The Transcontinental Railroad, 2012). Once they got into the high sierras black power was not strong enough, and they had to find something more powerful. Nitroglycerin was the solution to their problem. It was illegal to transport nitroglycerin, so what Central Pacific did was hire chemist James Howden to manufacture it on the site as it was needed (The Transcontinental Railroad, 2012). A secondary hazard of working in the mountains came from above

get the Irish to work on the C&O railroad because they were a part of the cheap labor system. The Irish however did not want to work for Huntington because they did not like the dangerous conditions that his workers faced. Huntington was using nitroglycerin which was very dangerous because it was more powerful than

blocked or narrowed. This can cause an uncomfortable pressure, fullness, and a squeezing sensation in the center of the chest. Known triggers are exertion and emotional stress. Stable angina is usually relieved with rest and medication such as nitroglycerin. Unstable angina is sometimes also called acute coronary syndrome. It causes unexpected chest pain and can occur during states of rest. The common

regular (HumuLIN R), warfarin (Coumadin), furosemide (Lasix), carvedilol (Coreg), captopril (Capoten), potassium (KDur), thiamine (Thiamilate), multi-vitamin (One-A-Day), trazadone (Desyrel), moxifloxicin (Avelox), amiodarone (Cardarone), and a nitroglycerin patch (Nitro-Dur). ECG revealed that the distal two thirds of the left ventricle was akinetic. Cardiac Catheterization revealed 80% occlusion of the left coronary artery and severe diffuse disease of the left anterior descending

high cholesterol, triglyceride and BP levels. These levels are caused by Room 3’s diet that is high in saturated fat and grease which dramatically increases the amount of lipids within the blood contributing to the formation of an atherosclerotic plaque leading to the impairment of blood flow (National Institute of Health, 2015b). After six weeks of treatment at the cardiac rehabilitation center and lifestyle changes, Room 3 admits that he is still under a lot of stress. During the administration

Some people said it could never be done; yet here we are with a railroad that stretches across America. Between 1800 and 1825, the only ways to travel were on dirt roads and natural waterways, which usually took about four or more months to complete a trip there. Raw materials traveled from coast to coast on wagons, horses, river ferries, or small boats. These long distances and slow transportation caused people to think of a new way to travel. The Transcontinental Railroad built over 150 years ago

Black powder was used for the majority of the railroad’s construction. But with the continuous use of it would take approximately well over a year to blast through the granite. It proved necessary to use nitroglycerin, however, the transport of the substance was banned. Central Pacific officials commissioned biochemist James Howden to develop the chemical on-site in order to comply with the new regulations. By June of 1867, the Central Pacific Railroad Company

Summary: John Doe, a fifty-year-old male presents to the Emergency Room with chest pain that has lasted for about 6 hours and is slightly relieved by nitroglycerin; the patient is also experiencing dyspnea as well as nausea. A fourth heart sound was discovered upon cardiac examination, and an angiogram revealed right coronary artery occlusion. Question: What is it that physiologically occurs during a myocardial infarction which leads to the formation of an S4 sound? Generate: Heart auscultation

ACUTE MYOCARDIAL INFARCTION An acute MI occurs when myocardial cells have reached the threshold of ischemia; which in turn cause the body’s myocardial cell repair mechanism to first become overwhelmed and then to completely fail. When this mechanism fails, myocardial tissue necrosis causing irreparable tissue/cell death occurs. The following are possible contributors to myocardial ischemia and ultimately myocardial infarction (tissue necrosis and cell death): • Increased myocardial metabolic demand

Administration: DOSAGE AND ADMINISTRATION Dexmedetomidine should be administered using a controlled infusion device. Dexmedetomidine dosing should be individualized and titrated to the desired clinical effect. For adult patients, Dexmedetomidine is generally initiated with a loading infusion of 1 (one) mcg/kg over 10 minutes, followed by a maintenance infusion of 0.2 to 0.7 mcg/kg/hr. The rate of the maintenance infusion should be adjusted to achieve the desired level of sedation. Dexmedetomidine

the Civil War, in the 1860s, and can be traced specifically to the 1862 Battle of Fredericksburg VA. E.A.L. Roberts received the original patent in 1866 for his discovery which he originally called fluid tamping. In the 1930s, they stopped using nitroglycerin, which made it much safer for the workers. Horizontal drilling and gas wells were precursors to hydraulic fracking in its specificity. Fracking was commercialized in 1949, and has been used commercially for about sixty five years now. Modern day

What is it? -a sudden and sometimes fatal occurrence of coronary thrombosis, typically resulting in the death of part of a heart muscle. -More than a million Americans have heart attacks each year. Pain or discomfort in one or both arms, the back, neck, jaw or stomach. Shortness of breath with or without chest discomfort. Other signs such as breaking out in a cold sweat, nausea or lightheadedness. As with men, women's most common heart attack symptom is chest pain or discomfort. When It Happens

With the purchases of western land in North America, the United States had gained a surplus of land. Since the West was new, it had new geological values such as precious metals and pastures great for cattle. Large quantities of people moved west to take advantage of this. The cattle industry was also great because of the species of the longhorn, which was very durable. With the West’s growth, a transcontinental railroad was built all around the United States. With this rise in the West, mining,

The Case of Paul Mills and Dr. Nancy Morrison Dr. Nancy Morrison was arrested for first-degree murder in 1996 for administering a shot of potassium chloride to her terminally ill patient Paul Mills in hope to hasten his death. Prior to his death, Paul Mills had undergone multiple operations including one to remove a part of his esophageal due to cancer, after each operations, he was left weaker and more dependent on hospital care and machines to be kept alive. He was in serious pain, suffering from
