Crimes of the Heart: A Case Study on Cardiac Anatomy Essay

Tiffany is worried about her newborn son. Ever since she brought Caleb home from the hospital it has been so hard to get him to eat and he seems to be breathing too hard all the time. At his one month check-up, the nurse tells her that Caleb has only gained one pound since he was born and Tiffany breaks into tears. Dr. Baker checks over Caleb in the exam room, taking extra time feeling and listening to his chest. After the exam Dr. Baker says, â€Å"When I listen to Caleb’s heart I hear an extra sound called a murmur. I want to use an echocardiogram and an ECG to get a good picture of all the parts of his heart.† After a full day of tests, Tiffany meets with Dr. Baker in his office. He explains, â€Å"After a careful review of all the information, I have discovered that Caleb has a hole in the heart muscle wall between his right and left ventricles. We call it a ventricular septal defect. That is probably why he has been so irritable and hard to feed. The hole is not very big, but he will still need to have surgery to repair it.† Although the thought of her tiny son having surgery is terrifying, Tiffany is relieved to know why things have been so tough at home. Short Answer Questions: 1. Caleb has abnormal heart sounds that tipped the doctor off to a problem. a. Name the normal sounds of the heart and indicate what causes these sounds. The two major sounds that are heard in a normal heart beat sound like â€Å"lub dub†. The â€Å"lub† is the first heart sound, commonly termed S1, and is caused by turbulence caused by the closure of mitral and tricuspid valves at the start of systole. The second sound, â€Å"dub† or S2, is caused by the closure of aortic and pulmonic valves, marking the end of systole. (STETHOGRAPHICS.COM) b. In relation to the normal heart sounds, when would you expect to hear the abnormal sound Dr. Baker heard? Explain your answer. When a valve is stenotic or damaged, the abnormal turbulent flow of blood produces a murmur  which can be heard during the normally quiet times of systole or diastole. (MED.UCLA.EDU). In relation to the systole and the diastole a murmur can be detected between the quiet times between the two. Normally, a murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. (NIH.GOV)That is what Dr.Baker probably heard when doing the examination. 2. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? Explain your answer based on blood pressure and resistance in the heart and great vessels. It goes left to right during systole. The difference is normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, and then is pumped into the lungs where it receives oxygen. Oxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle, and then is pumped out to the body through the aorta. But when an infant has ventricular septal defect it still allows oxygen-rich (red) blood to pass from the left ventricle, through the opening in the septum, and then mix with oxygen-poor (blue) blood in the right ventricle. (ROCHESTER.EDU) but instead when systole occurs the blood gets mixed because of the septum therefore heart needs to pump harder to ensure that enough blood with oxygen reaches the body. 3. When an echocardiogram is performed, the technician color-codes oxygenated blood (red) and deoxygenated blood (blue). a. In a healthy baby, what color would the blood be within the right and left ventricles, respectively? Right ventricle: deoxygenated (blue), Left ventricle: oxygenated (red) b. In Caleb’s heart, what color would the blood be within the right and left ventricles, respectively? Left ventricle: oxygenated (red). Right ventricle: will have mixed blood so it will be red and blue because the opening between the two ventricles has an effect similar to a connection between the atria: When the more powerful left ventricle beats, it ejects blood into the right ventricle and pulmonary circuit. (A&P book pg. 677) 4. What happens to Caleb’s systemic cardiac output as a result of his  ventricular septal defect (VSD)? Explain your answer. Caleb will produce lower cardiac output because a left-to-right shunt at the ventricular level reduces LV output by the amount of the shunt because of this the body’s compensatory mechanisms will increase intravascular volume because of this lowered cardiac output until LV end-diastolic volume is sufficient to pump both a normal cardiac output and the proportionate left-to-right shunt. (AHAJOURNALS.ORG) 5. Based on the location of Caleb’s defect, what part of the conduction system might be at risk for abnormalities? Well since Caleb has a hole in his heart muscle wall these parts of the conduction system might be at risk for abnormalities the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers.

Preparation for Value Management Study designed for TechWatt Essay

Preparation for Value Management Study designed for TechWatt Corporation - Essay Example In preparation for the Value Management Study, TMK Services has determined the need for this preliminary report that will address the specific issues that should be evaluated during the first meeting of the project briefing stage. This report will include details of what should be contributed to the Value Management Study, and who will be involved in the process. In addition, TechWatt will need to provide certain information for the Study, which will be addressed. Finally, a proposed agenda will be submitted for approval. Top managers of TechWatt must be involved in every aspect of this process and, since the company is not large, they will be directly monitoring each feature of the process without exception. At the early stages of decision making, there is no need for any delegation of responsibility. As the process proceeds to the construction phase, At the outset, TMK Services has been informed that the funds allocated by TechWatt for the proposed HQ total approximately five million pounds. With that in mind, the first logical step in this process must be to determine a suitable location for building and determine what the cost of the land will be. While some locations may seem more desirable from a strictly logistical or geographical standpoint, consideration must be given to the relative cost of land in any given area being considered. We would suggest that TechWatt management not limit themselves to only one possible location at this stage. Going into the Value Management Study meeting, it would be beneficial to have at least two, if not three possible locations on the table. Considering what has been occurring with the price of land in recent years, it becomes imperative to make the proper decision on location. For example: From 1983 to 2002 the cost of one hectare of land in London went from 0.76m to 5.5m. However, in the South West, the price went from 0.18m to 1.7m. Finally, the lowest prices for land are found in Yorkshire with prices raising from 0.1m to only 0.87m per hectare. (UK Land Prices Rocket, 2003) Prices for land vary throughout additional areas of the country, and specific numbers can be provided upon request, however the purpose of providing these statistics is simply to provide the basis for TechWatt management to understand the importance of this part of the decision making process. Obviously, the cost of the land on which the HQ will be constructed will play a major roll in determining the amount of finances remaining for the building process. 3 Although a full hectare of land may not be necessary for this project - that is a determination that will be made at a later date - understanding the cost of land in various locations must be a vital part of the process for TechWatt management. Other factors will need to be considered regarding location, as well. These include: accessibility of location (is it close to majors thoroughfares and easily accessible from airport); quality of surrounding area

Technology of Information Security Essay Example | Topics and Well Written Essays - 750 words

Technology of Information Security - Essay Example As technological advancement keeps coming, several reliable cryptography methods are continuing to emerge. Data encryption has a number of advantages and disadvantages. Its disadvantages come mainly because the technology is sometimes not used as required. Cryptography is a very powerful and important technology that can be used to protect information sent to emails and all financial based transactions. Information needs to be shared in order to make various decisions that govern various activities. For this reason, information should be as confidential as possible for sustainability and accuracy of its use. Data encryption techniques offer a solution for the protection of information against all third parties. The techniques are basically needed for information to be encrypted whereby one party shares its information with a recipient. On the other hand, enemies can hack into people’s accounts and plot violence against a country with knowledge of cryptography. Some governments want to restrict its use for fear of criminals and spies using the technology for their good and to the disadvantage of the nation. How Encryption Technique works Encryption is a process whereby messages are converted into a form that has been created that without decrypting or deciphering, they cannot be read. Encryption uses a systematic procedure or algorithm which converts messages or data to their original form. The cryptologists are engaged in competition that will never end in a bid to create better and stronger techniques that will be used by parties to protect their data. Although other methods of deciphering exist, the recent systems are more powerful to an extent that they are almost unbreakable even with the use of powerful computers. The new cryptosystems use mathematical formulae that are very complex and which effectively resist breakthroughs. The Use of PGB There are several popular encryption systems used in the world today. They include the data encryption standar d (DES), pretty good privacy (PGB), and the Rivest Shamir, Adleman (ARS) system. The DES system uses a single key and it has been developed in the USA. The RSA on the other hand uses two keys and was generally made just for the public use and named after the people who developed it (Frazier2004). Pretty Good Privacy (PGB) helps internet users to keep all their communications private. It is a two key system which enables a computer to send encrypted messages using a chosen private key that only the sender knows. All the computers that will receive the email message are given a copy of the private key which later establishes the message sender. When using the public key method, the one who sends the message and the receiver are both able to authenticate each other and also protect the message which is usually secret. Advantages of Encryption Techniques Encryption techniques make information unreadable to people who are not supposed to access the information. This is very important to many organizations because no third party can access information without being allowed to do so by the sender. The information cannot be accessed even through the administrator’s server leave alone other computers. This improves loyalty and secrecy in the organization or any governments in the world today. Data encryption is regarded as a national issue by governments because it majorly

What does the Government, Local Community and Employers Want from Essay

What does the Government, Local Community and Employers Want from Colleges - Essay Example In that line, one can clearly tell that colleges are very fundamental institutions in modeling any country’s economy. The better the training offered by colleges the more the surety of good economic contributors. It is evident that communities and employers have to maintain close and detailed watch of the various colleges to scrutinize the kind of graduates they produce to the community and production plants. The governments also have some stakes in the operations and output of colleges in terms of the quality of graduates they release into the market. Communities’ Expectations from Colleges Colleges are not only centers for learning but also employment sectors that offer job opportunities to service providers to the students and learners. Keller reports that colleges are grouped into two different levels depending on the driving body. Keller indicates that there public colleges, which are specifically driven and monitored by governments of different regions. The other division of colleges according to Keller is the private colleges, which are actually monitored and managed by private bodies or organizations and not governments. The listed division of colleges recruits workers from the societies and offers different portions of wages to the employees at different levels of operations. Communities have it as a routine that private colleges will always offer higher incomes to it workers at different levels of operation (Keller). Public colleges on the other hand are institutions that offer lower income margins as compared to the private counterparts. However, Keller provides clarity that public colleges with the low salaries offered to employees have well established retirement pension schemes that rewarded to the retired workers. Communities therefore will always keep careful look at the public colleges to reward pensions to their former workers within a certain period. The fact is contrary to the private colleges, which do not initiate in long-ter m pension plans. In addition, communities expect that workers in the public sectors will comply with the national retirement age and retire at the exact age indicated in the legislations of a country. Private colleges on the other hand do not have close sensitivity on the retirement age of its employees and could at times contract aged and highly skilled professionals to continue serving the institutions. For that matter, members of the community who happened to work in the public colleges and have attained the retirement age will call back to the private colleges in search of employment (Keller). In the views of Anna, communities keep watch on colleges to lower the costs of learning in order to accommodate particular individuals who never got the opportunities to advance their education to university levels. Furthermore, communities view colleges as the appropriate avenues for undertaking lifelong learning that is essential for long-term success of individuals. Anna further states that communities expect colleges to produce graduates who can challenge and compete with individuals who underwent degree programs. Additionally, communities expect colleges to offer high standards of education guaranteed by highly qualified and hardworking teachers (Gladden). In addition, communities expect colleges to act as crossing bridges to universities for individuals who never performed better in the high schools (Gladden). Due to the perceived small numbers of students in college, communities expe

Analysis of Asian American Essay Example for Free

Analysis of Asian American Essay The United States has become the most diverse society on the face of the earth. For more than a century, most immigrants to the United States were Europeans—Germans, English, Italians, and so forth. However, according to â€Å"Globalization and Contemporary Immigration to the United States† by Min Zhou and J. V. Gatewood, â€Å"non-European immigration to the United States began in the late 1960s and has accelerated at rapid speeds since the early 1990s after a long hiatus due to restricted immigration. † More than one million people a year migrate, mostly from Asia and Latin American- is transforming America into a multicultural society. At the same time, diversity became a distinguishing characteristic of contemporary Asian American. Cultural, social, economic and geopolitical factors have contributed to the diversity and also has brought new challenges for immigrants and their children to adapt themselves to the new environment. (Min Zhou and J. V. Gatewood) There are four aspects about â€Å"the development of a coherent vision for future Asian American† as what Min Zhou and J. V. Gatewood described. Firstly, variously national origins, which make impact on both the immigrant generation and the second and third generation in language and religions. Secondly, socioeconomic diversity brings about different kinds of mobility patterns. Thirdly, diverse settlement modes influence the development of Asian American community. Finally, â€Å"immigration complicates intergenerational relations and ethnic solidarity. † As what Min Zhou and J. V. Gatewood referred, â€Å"the Philippines, China/Taiwan, Korea, India, and Vietnam have been on the list of top-ten sending countries since 1980. †Even though there were different kinds of laws to restrict immigration from the â€Å"Asian-Pacific triangle†, Asian immigrants found other ways to become eligible citizen. For example, marrying white Americans. With the development of globe economy, the U. S. immigration policy had been changed. On the one hand, the United States sought cheaper labor and resources abroad to develop the globalization of its economy. â€Å"Since the 1980s, about on e-third of the engineers and medical personnel in the U. S. labor market have come from abroad-mostly from India, China, Taiwan and the Philippines. † (Min Zhou and J.V. Gatewood) Further, more and more Asian study abroad, therefore, many international students, namely, foreign students, had found permanent employment in America so that they could stay here. On the other hand, globalization had played a significant role in immigration. For one thing, developing countries’ economics and occupational structures were interposed by the U. S. investment. The U. S. imported the abroad material and then processed, finally, exported to those developing countries. For another thing, with the increase number of labor demand, rural-urban migration increased rapidly.
