  • Chagas Disease

    Treatments & Prevention Treatment during the acute phase of Chagas Disease is critical because it rapidly reduces parasitemia, decreases the chance of death and reduces the likelihood of chronic Chagas Disease (Kaplan and Porter 3). Only two drugs have been proven to improve the patient during the course of this disease and those drugs are nifurtimox and benznidazole. However, treatment from either of these drugs is difficult due to them not being FDA approved. Nifurtimox and benznidazole can…

  • A Career In Space Exploration

    Since the origin of civilization, humanity has always been perplexed by outer space. We look at the sky and for the first time in our lives, we feel minuscule. In a world where humans are at the top of the hierarchy, space seems to swallow us entirely. Space exploration’s origin can be traced back to curiosity. Exploring space not only answers numerous questions we all share about the universe, it also grants us a deeper look into the world we inhabit. Try imagining a new color. Impossible,…

  • Heart Waves Lab Report

    separate the ventricles from the arterial system. The aortic valve separates the left ventricle from the aorta while the pulmonary valve divides the right ventricle and pulmonary artery. AV valves and semilunar valves perform an important role in the cardiac cycle because they only allow blood flow when pressure gradient is reached. During ventricular filling, the AV valve remains open due to atrial pressure being higher then ventricular pressure. Concurrently, the semilunar valves are closed as…

  • Hypertrophic Obstructive Cardiomyopathy

    breathing. My nurse alerted me what my heart monitor said my heart was doing, and being a retired nurse with cardiac care experience, I remembered to cough, and it worked! My V-Tach stopped. However what seemed to be a dozen of Cardiologists entered my room shortly after to tell me that they thought a internal defibrillator/pacemaker was necessary to prevent me from having 'sudden cardiac death.' With wide eyes, I agreed almost immediately. After the second surgery, my heart went to…

  • Calcium Signaling

    Calcium ions are vital for cellular signalling, as once they enter the cytoplasm they use allosteric effects caused by indirect transduction pathways such as G protein-coupled receptors. Calcium signalling is cause by gradients across the plasma membrane, as the resting concentration of Ca2+ in the cytoplasm is normally kept ˷100 nM, compared to the extracellular concentration which is ˷1.5mM. To continue low concentration within the cell, Ca2+ signals can be generated either from extracellular…

  • Frog Caffeine Experiment

    spontaneous increase in blood pressure, although it is unclear of exactly why blood pressure increases when caffeine is introduced to the system. Due to the increase of the heart rate and blood pressure, there is higher susceptibility to heart issues like cardiac arrhythmia (Robertson et al., 1978). I hypothesize that the heart rate has a direct correlation to the ventricular pressure, which could explain the increase in the blood pressure. When the ventricular pressure increases, more blood is…

  • Heart Failure Nursing

    Staging of heart failure in patients is achieved through two measures, an assessment of the patient’s symptoms as well as an objective assessment. The most severe of these two classifications Stage IV D can be described as an inability to perform any physical activity without discomfort and ‘objective evidence of severe cardiovascular disease’ (American Heart Association, 2015). There are difficulties in providing optimal care in these patients and this is due in part to the rate of decline in…

  • Physiological Effects Of Coronary Heart Disease

    Coronary angiography (also known as cardiac catheterization) is usually employed to diagnose the majority of cases of CAD, which involves the introduction of a long, flexible tube (that is, a catheter) into an artery (generally the femoral artery due to its accessibility) wherein it is then…

  • Ischema Case Studies

    as the flow of blood through arteries and capillaries that deliver oxygen and nutrients to the cells and removing cellular waste from the body (Giddens, 2013, p. 148). For us to maintain optimal perfusion, we need are heart to generate sufficient cardiac output. This means transporting the blood through patent blood vessels to supply the tissues throughout the body. Impaired perfusion may occur when the blood supply is reduced or completely interrupted (Giddens, 2013, p. 148). A term that…

  • Hcr 220 Week 5 Celta Reflection Journal

    was ready to be discharged. She was alert and oriented. Since she had cellulitis, we had to monitor her vitals for fever and white blood count for leukocytosis. The trend shows that she is improving with her vancomyosin. She also had a history of cardiac arrhythmia and hypertension, so we have her on metoprolol. I was going to give her heparin as a prophylaxis but she denied it. Upon assessing her I found that she was at a falls risk because she had macular degeneration. What I taught her was…
