Effectiveness of the Artificial Heart

Effectiveness of the Artificial Heart   Zeeshan Bhalwani   Artificial Heart The human heart is a wondrous structure of engineering. In the body of the average adult, the heart is the tenacious muscle that beats approximately 100,000 times each day, pumping blood through veins and arteries that extend upwards toward the brain and downwards towards the toes. It is no big surprise biomedical engineers have had a difficult time assembling a mechanical replica which is to function similarly as the heart and to keep patients with heart failure alive. Although comparative developments date back to the late 1940s, the first artificial heart was effectively implanted in a human was the Jarvik-7 in 1982, constructed by Willem Johan Kolff and Robert Jarvik (Strickland). The artificial heart is a prosthetic device that surgically replaces both ventricles and all valves of a heart used by adults with heart failure, and is becoming more prominent as innovation is advancing. Artificial hearts are normally used to delay the time to heart transplantation, or to indefinitely replace the heart in case heart transplantation is not possible. The most affluent impact of the artificial heart is that it saves over 5,000 lives every year (SynCardia). Additionally, this invention has had a beneficial impact on society because a fully functional artificial heart lowers the excessive need for heart transplants, since the demand for donor hearts surpasses supply. An example of someone who has been greatly assisted by the artificial heart is Pietro Zorzetto. He had an artificial heart in him for nearly four years, prior to his successful heart transplant on September 11, 2011 (Drumwright). Overall this device was of assistance to many people, but unfortunately there are also consequences that are turning up as progress is being made on the artificial heart. The consequences associated with the artificial heart are primarily unforeseen and bad, although little good can be seen. According to CardioWest, a certain artificial heart is designed to be attached to a power source outside the body through holes in the abdomen. These holes allow harmful bacteria getting inside the body which could potentially cause an infection. Additionally, since the mechanisms are so complex, they can malfunction in different ways. An artificial hearts pumping rate may not be exactly right, power may fail or parts altogether may stop working, which consequently would lead to sudden death. Another disadvantage of the artificial heart is that not all patients have a body size that allows the device to be implanted into the chest, making small people incapable of   receiving the device. As innovation is advancing and technology is progressing, these issues are beginning to diminish and new ways of developing the artificial heart are being introduced. According to MIT, the artificial heart is being enhanced to combine synthetic and biological materials as well as sensors and software to detect a patients level of exertion and adjust output accordingly. According to Carmat, a company concentrated on developing the latest bioprosthetic heart, it will comprise of two chambers each divided by a membrane which will hold hydraulic fluid. A motorized pump will move the fluid in and out of the chambers allowing the blood to flow through the chambers. The blood-facing side of the membrane is made of tissue procured from tissue that surrounds a cows heart, to make the device more biocompatible. The benefit of bioprosthetic hearts is they are not rejected by the bodys immune system. This is because they are made from metals and plastics, so the body does not recognize them as foreign and attack them in the same way it does with a manifold of living tissue. Furthermore, Pennsylvania State University researchers are developing a prosthetic hea rt powered by radio-frequency energy that is absorbed by the skin. Overall, these particular advancements are what will make the artificial heart sought-after. To conclude, heart failure is the leading cause of death all over the world. Most people die from the chambers of the heart failing to push enough blood through the body. A solution to heart failure was initially surfaced in the late 1960s. It had also required the advent of immunosuppressants. Around a decade later, the first successful artificial heart was developed and, the average survival rate of heart transplant patients increased to more than 5 years. The incessant furtherance of technology today will eventually lead to the creation of the perfect artificial heart and will be able to help every common man in need.

Corporate Culture and the Effective Execution of Strategy Essay

What is corporate culture? Corporate culture refers to the character of a company’s internal work climate – as shaped by a system of shared values, beliefs, ethical standards, and traditions that define behavioral norms, ingrained attitudes, accepted work practices, and styles of operating. Every company has its own unique culture. The character of a company’s culture or work climate is a product of the core values and business principles that executives espouse, the standards of what is ethically acceptable and what is not, the work practices and behaviors that define â€Å"how we do thing around here,† its approach to people management and the â€Å"chemistry† and the â€Å"personality† that permeates its work environment. The chief things to look for include the following: 1. The values, business principles, and ethical standards that management preaches and practices. 2. The company’s approach to people management and the official policies, procedures and operating practices that paint the white lines for the behaviour of company personnel 3. The atmosphere and spirit that pervades the work climate. 4. The way managers and employees interact and relate to each other 5. The strength of peer pressure to do things in particular ways and conform to expended norms. 6. The actions and behaviours that are explicitly encouraged and rewarded by management in the form of compensation and promotion. 7. The company’s revered traditions and oft-repeated stories about â€Å"heroic act† and â€Å"how we do things around here†. 8. The manner in which the company deals with external stakeholders Discuss the ways in which corporate culture can either help or hinder effective execution of strategy. Strong culture can help a powerful effect on the strategy execution process. This effect may be positive or negative since a company’s present culture and work climate may or not be compatible with what in needed for effective implementation and execution of the chosen strategy. A culture that is grounded in actions, behaviours, and work practices that are conducive to good strategy implementation assists the strategy execution effort in three ways: 1. A culture that is well matched to the requirements of the strategy execution effort focuses the attention of employees on what is most important to this effort. Moreover, it directs their behaviour and serves as a guide to their decision making. In this manner, it can align the efforts and decisions of employees throughout the firm and minimize the need for direct supervision. 2. Culture-induced peer pressure further induces company personnel to do things in a manner that aids the cause of good strategy execution. The stronger the culture, the more effective peer pressure is in shaping and supporting the strategy execution effort. Research has shown that strong group norms can shape employee behaviour even more powerfully than can financial incentives. 3. A company culture that is consistent with the requirements for good strategy execution can energize employees, deepen their commitment to execute the strategy clearly, and enhance worker productivity in the process. When a company’s culture is grounded in many of the needed strategy –executing work for, and the merits of what the company is trying to accomplish. As a consequence, greater numbers of company personnel exhibit passion in their work and exert their best efforts to execute the strategy and achieve performance targets. In sharp contrast, when a culture is in conflict with what is required to execute the company’s strategy well, a strong culture becomes a hindrance to the success of the implementation effort. Some of the very behaviors needed to execute the strategy successfully run contrary the attitudes, behaviors and operating practices in the culture. Such a real dilemma for company personnel. Culture-bred resistance to the actions and behaviors needed for good strategy execution, particularly if strong and widespread, make a difficult problem that must be cleared for a strategy’s execution to get very far.

Maslow’s self-actualization was developed from his hierarchy of needs. In the hierarchy of needs there are seven stages. Maslow did not feel that self-actualization determined ones life; rather, he felt that it gave the individual a desire, or motivation to achieve budding ambition (Gleitman and Reisberg). As a person moves up Maslows hierarchy of needs, eventually they may reach the summit self-actualization (Gleitman and Reisberg). The first stage is physiological needs, which are where an individual will find food and water; also they will be able to use basic functions such as sleeping and breathing.

He is stating with this that it is nearly impossible for someone to achieve the full potential. Maslow argued that humans have an innate drive toward personal growth that is, evolution toward a higher state of being (psychology applied to modern life, p. 53). Maslow focused on human’s potential and how humans will fill that potential they have. Maslow stated the levels of motivation could happen on different levels at any time. Instead of stating that the individual focuses on a certain need at any given time, Maslow stated that a certain need â€Å"dominates† the human organism, (Maslow, A. (1954).

What people need to realize is it doesn’t matter what other people think about them no one is going to bring them happiness. The only way someone can feel well about themselves and be happy with their-self is if they go out and find what makes them happy.

The Need For Gun Control in America Essay - 921 Words

The Second Amendment of The United States Constitution states, â€Å"[a] well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms shall not be infringed. An AR-15 is semi automatic, high capacity firearm with a muzzle velocity of over three thousand feet per second. The rifle will fire as fast as one can pull the trigger. This commando style weapon, with high capacity magazines, in the hands of a mentally or emotionally unstable individual, is a recipe for disaster that could cause great harm and death to the innocent. Although Americans have a constitutional right to bear arms, there need to be precautions in place to insure the safety of the people.

One-third of the shooters in the past century had made prior threats. In an official FBI document, it states, â€Å"Behavior is an expression of personality, but one bad day may not reflect a student’s real personality or usual behavior pattern. Accurately evaluating someones behavior requires establishing a baseline — how he or she typically behaves most of the time† (FBI 4). Peers of individuals who suffer from mental illness must be attentive to peculiar behavior and take all threats seriously. When people treat situations like these with care and responsibility, often the shooter’s plans are foiled. These simple steps could save countless lives. In the United States alone, over thirty-one thousand people die annually as a root to firearms. The American Medical Journal concluded, â€Å"there is a positive correlation between guns per capita and firearm relate deaths† (AMJ 2).

string(87) " should at all times deal honestly and openly with patients concerning medical errors\." Surgical Site Infections Elizabeth Griffor HCA 375 Continuous Quality Monitoring Accreditation Instructor: Annajane Schnapp October 27, 2012 I chose to do my paper on the hospital-acquired condition of surgical site infections. In this paper I will discuss what a surgical site infection is, why it is considered preventable, the legal implications related to the patient, the role disclosure plays, accreditation expectations, and analyze the cost of continuous quality monitoring as it relates to quality. Surgical site infections account for 40 % of all hospital-acquired infections ( HAIs) and are unnecessary and largely preventable. We will write a custom essay sample on Surgical Site Infections or any similar topic only for you Order Now Use of antibiotics is fundamental in preventing surgical site infection and includes three core elements: 1. appropriate selection, 2. timing of the first dose, 3. and discontinuation postoperatively. It used to be the standard practice to â€Å"shave and prep† a patient prior to surgery, but a study done in 1992 revealed that surgical site infections were 50% lower in surgery patients whose hair was removed with clippers rather than a razor. One of the most common complaints from surgery patients is being cold in the holding area, operating room, and the post anesthesia care unit ( PACU) . This is uncomfortable and can increase risk of complications; such as surgical site infections. Glucose control is also important as a method for decreasing surgical site infections ( Frances, 2005). Guidelines for preventing surgical site infection are at the preoperative stage, intraoperative stage, and postoperative stage. They are as follows: 1. Preoperative stage: Patient preparation- Identify and treat all infections before surgery; postpone surgery if possible until infection is resolved. * Do not remove hair by the incision site unless it interferes with the operation; use electric clippers immediately before surgery if hair must be removed. * Have patients bathe or shower with an antiseptic the day of the surgery or the night before. * Thoroughly wash and clean at and around the incision site to remove gross contamination. * K eep hospital stays as short as possible to limit the patient’s exposure to nosocomial infections. Antimicrobial prophylaxis- * Work with the physician, pharmacist, and administer a prophylactic antibiotic only if it is indicated; antibiotic chosen should be effective against common pathogens that cause surgical site infections. * I. V. administration of the antibiotic should be timed so it is concentrated when the incision is made. * Do not use Vancomycin for antimicrobial prophylaxis routinely. Surgical team preparation- * Keep fingernails short, no artificial nails; bacteria and fungi can colonize on your hands if you wear artificial nails. Surgical team members who have signs or symptoms of an infectious illness need to promptly report this to their manager and occupational health service personnel. * Surgical team members that have draining skin lesions should be relieved from duty until infection has been ruled out, they have had therapy, or the infection is gone. * It is also suggested that no hand or arm jewelry be worn, as well as nail polish. 2. Intraoperative stage: Ven tilation- * Maintain ventilation in the operating room and maintain a minimum of 15 air changes per hour. Keep the operating door closed as much as possible. * Limit the number of staff entering the operating room. Surfaces and equipment- * Clean surfaces or equipment with hospital disinfectant if they are soiled with blood or body fluids before the next operation. * Do not perform special cleaning or closing of operating room after contaminated or dirty operations. * Sterilize all surgical equipment according to guidelines. * Assemble sterile equipment and solutions just before using them. Surgical attire- * Before entering the operating room, a surgical mask and hood that covers he hair on the face or head must be worn. * Sterile surgical gloves must be worn, putting them on after a sterile gown. * Shoe covers are not necessary for preventing surgical site infections. Vascular access- * Adhere to the rules of asepsis when placing intravascular devices and administering I. V. drugs . 3. Postoperative stage: Incision care- * Use a sterile dressing for 24-48 hours on an incision after surgery. * Wash your hands before and after any contact with the surgical site, even when changing the dressing. Use a sterile technique when changing dressings. * Teach the patient and family about incision care, signs or symptoms of surgical site infection, and when to report any symptoms (Adams, 2001). Following these guidelines can effectively reduce or prevent surgical site infections. Although nothing is 100% full proof, surgical site infections can be reduced and prevented in most situations. If an infection is not present at the time of admission and becomes evident after 48 hours of hospitalization; it is considered to be hospital acquired. Following the above mentioned guidelines indicates quality health care practices. By using these techniques, surgical site infections will be prevented and reduced resulting in quality care; benefiting both the patient and the hospital. A legal implication related to a patient developing a surgical site infection, results in more cost to the hospital, less profit, and leaves them open to possible lawsuits. Hospital acquired infections affect 1. 7 million hospitalizations, cost $ 8. 1 billion to treat, and lead to 2. 3 million total days of hospitalization. Infections are the fourth most expense in hospitals, costing $ 252,600 per hospital on average, and each afflicted patient requires $ 24,500 more in care on average as a result. Examples of lawsuits filed due to hospital infections are as follows: July 2008, couple awarded $ 2. 58 million after the patient contracted a deadly type of staph infection ( MRSA), resulting in the loss of a kidney, and an amputated leg and foot. November 2008, jury awarded $ 13. 5 million to a woman’s family after she died of an infection aused by flesh-eating bacteria; contracted during cancer treatment. And November 2008, a woman reached a confidential settlement of $ 16 million when a hospital failed to detect a flesh-eating bacteria, before and after she gave birth, resulting in the loss of three limbs and several organs ( Gaffey, 2010). According to the AMA’s code of ethics, it is a requirement that a physician should at all times deal honestly and openly with patients concerning medical errors. You read "Surgical Site Infections" in category "Essay examples" Several doctors cite the risk of litigation as grounds for caution when discussing medical errors. Practicing defensive medicine such as ordering more tests or consults has become the norm to avoid malpractice suits. 94% of physicians say they would inform a patient if a mistake was made that caused an injury. Concern regarding legal liability which might result from telling the truth should not affect a physician’s honesty with a patient according to the AMA’s Code of Medical Ethics, however some skeptics maintain that it is easier to brag about virtue, than actually follow it ( Rice,2002). For the most part physicians agree that honesty is the best policy. Many doctors in a survey confessed to errors such as; prescribing the wrong medications, wrong dosage, misinterpreting x-rays, misinterpreting lab reports, etc†¦ One physician stated that being upfront about his mistakes, talking to the family, and apologizing probably avoided a lawsuit. Most doctors agree that it is better to be upfront about a mistake for several reasons, they are: 1. That it always comes out eventually, 2. Dishonesty causes more damage and loses the public’s trust, 3. Honesty decreases the chance of being sued, as well as it is the right thing to do, and 4. They want their patients or family to hear it from them first ( Rice, 2002). Communicating with the patient or family, educating them on the procedure and signs or symptoms to look for can prevent surgical site infections. Being open and honest with the patient and their family when an error occurs can possibly help to avoid a lawsuit. Honesty is always the best policy when providing quality health care. In October 2008, CMS announced that it would no longer pay for hospital-acquired conditions. It is their view that if a hospital has a good standard of practice and multidisciplinary care guidelines that these events should not happen and can easily be prevented. This is not to penalize health care, but to improve the safety of patient care and improve the quality of care by establishing standards of care and protocols. The Joint Commission has also implemented similar reporting and nonpayment initiatives to improve safety and improve the quality of care ( Lisa, 2009). The Joint Commissions new national patient safety goal to prevent surgical site infections includes a requirement to look for surgical site infections for up to 30 days after a procedure. The Center for Disease Control ( CDC) estimates that between 12% and 84% of surgical site infections are found after patients are discharged from the hospital. Joint Commission surveyors will be looking to see if the following protocols are being followed: * Hospital educates health care workers involved in surgical procedures about healthcare –associated infections, surgical site infections, and the importance of prevention. Before all surgical procedures, the hospital educates patients/family about surgical site infection prevention. * Hospital implements policies and practices aimed at reducing surgical site infections. * Hospital conducts periodic risk assessments for surgical site infections. * Measurement strategies follow evidence-based guidelines and surgical site infections are measu red for the first 30 days after surgery. * Hospital supplies surgical site infection rate data and prevention outcome to leaders, practitioners, nursing staff, and other clinicians. Antimicrobial agents for prophylaxis used for a particular procedure or disease are administered according to standards and guidelines. * Administer I. V. antimicrobial prophylaxis within one hour before incision. * Discontinue the prophylactic antimicrobial agent within 24 hours after surgery. * When hair removal is necessary, use clippers or depilatories ( Hospital Infection Control, 2008). Localized improvement occurs when a team is developed to look at a specific problem; such as the rate of surgical site infections. Organizational learning occurs when this process is ocumented and results in the development of policies that are implemented; such as a protocol for preventing surgical site infections. Process reengineering occurs when a major investment blends internal and external resources to make c hanges; such as being accredited by the Joint Commission and following their guidelines for prevention of surgical site infections. Evidence-based medicine involves the selection of the best clinical practices; implementing surgical site infection control guidelines or protocol to reduce cost and increase profit (Sollecito Johnson, 2013). The most effective strategies for improving health care quality are: clinician-directed audit and feedback, clinical decision support systems, specialty outreach programmes, continuing professional education based on interactive small-group case discussions, and patient-mediated clinician reminders. Pay-for-performance strategies directed to clinician groups and organizational process redesign are modestly effective ( Scott, 2009). In my opinion using the organizational learning strategy would generate the best outcome and cost the least to implement. Having a team put together to gather data on surgical site infections and implementing a protocol or guidelines to follow to prevent these events would result in less cost and increased profit. In conclusion, surgical site infections are for the most part preventable. Following protocols or guidelines can greatly reduce surgical site infections. Educating staff, patients, and their families, can have a big impact on preventing surgical site infections and implementing these strategies reduces cost and increases profit.

Question: Discuss about the Research Directions for Internet of Things. Answer: Introduction: The statement the best interface for a system is the no user interface means that computers have become a threat human beings as they are currently performing tasks that used to be done by humans. It complicates human lives instead of making them better (Hecht, 2015). For instance, lays out how we came about this application obsessed point and how we could change things and ensure that no individual is using the best tool for a job. It could either be or not an app such as those employed in smartphones like Android. Most organizations together with the app designers are trying to change and use the screens and apps thinking they are making the task suitable, but they are achieving the opposite. The statement can also be linked to an incident where companies are trying to change them to be conversant with their ecosystem (Tyson, 2004). This interface mostly favors a company's partakers but not their experience. In no user interface, user experience does not significantly matter as it is an option when individuals are solving problems. People are supposed to be focused more on things that are more alluring apart from the apps (Borgia, 2014). The app that there is an application that can perform all tasks has worsened the user design. People should embrace the actual situation and not that which performs functions on the screen. It is made up of one or more pairs of electrical son arranged in a spiral. They transmit both analog and digital data. They are made up of two copper wires about 1 mm thick. The wires are twisted to minimize interference from the environment around. The cables have magnetic interference when the two wires are laid parallel. It is one of the cheapest hence highly demanded. For long distance connections, they vary from a range of 5 to 15 cm and thickness of 0.4 mm to 0.9 mm. in this situation, the transmission of a signal is about 5 to 6 km. There are two distinctions of twisted pair cables; shielded twisted pair and unleashed twisted pair. The shielded twisted pair is made of copper wires covered with foil or in a braided mesh and a PVC cover as the outside cover. Braided mesh protects electromagnetic penetration as the foil prevents the magnetic fields. The unleashed consist of color copper wires without any foil or braid for insulation against electromagnetic. The wires within each cable are different. UTP cables are further subdivided into categories according to their purpose and transfer rates. It is similar to the twisted pair made of two conductors but designed differently to allow it to function better and over high range frequencies. A good example is the TV antennae. They have a metal foil and braided cable to guard against electromagnetic interference. There are two types of coaxial cables that are, thin net and thicket (Borgia, 2014). The small net is about inch thick and is mostly used for short distance transfers. They directly link to a workstation network adapter card using a British naval connector. It moves data to a distance of about 185 meters. The coaxial is around inch thick and can transfer data over longer distances than the thin net.it is commonly used as a support point to connect smaller thin net based networks and transfers data to a maximum distance of 500 meters (Kopetz, 2011). The bandwidth of a coaxial cable is 10 Mbps. On the aspect of coaxial cable basing the on interference, is that they are resistant to the effect of attenuation up to a specific length of up to 100 meters. Regarding the cost, it is more expensive than the twisted cable and less than the optical cable. They are more secure than twisted cables and less secure than optic fiber cables. It carries digital data by use of optical fiber signal. They transfer data in modulated pulses of light. It is made up of cylinder glass known as the core rounded by a concentric layer of glass referred to as the cladding. An optic comprises of two cables one for transferring and another for receiving data. The core uses a high optical quality transparent plastic and coating made of gel which reflects signals back to the fiber hence the low signal loss. There are two types of fibers; single and multi-mode fiber. The single mode fiber uses a single ray of the light in carrying a transmission over a long range (Kopetz, 2011). Multimode fiber uses some light rays at the same time with each ray running to the most reflective angle to hold transmission over short ranges. Multi-Mode fiber optic can deliver data up to 1 Gbps. It functions on the wavelengths of between 85p nm and 1300 p nm. Fibre optic cables have a bandwidth of 100 m or less; the bandwidth is not limited. It is most expensive compared to twisted and coaxial. Its interference level is much lower than the others and is also most secure. They are subdivided in the following type; Type of sensor Merits Demerits Application Ultrasonic sensors They detect (sense) all materials It has low resolution Used in doors for security Curb collision Limit switch Sensors They are cheap They have high current capability Must physical contact with the target They respond slowly They are used in basic end of travel sensing Capacitive sensors They are able to detect non-metallic targets They detect via some containers They sense highly to environmental changes Used for level sensing Inductive sensor Simple to install Easy to predict They only sense metallic targets Used in industries and machines Photo electric sensor They have a long life They sense over long distances They are fast in responding. Sensing range is affected by reflectivity and color of the target Lens are contaminable Used in packaging Handling material Detecting parts RFID Advantage They can hold more data than barcodes Used for monitoring the health records for patients Used for security and attendance reasons Disadvantages Coverage is limited to 3 meters Programming the RFID is time-consuming External electromagnetic interference can block remote reading Technology brings about loss of jobs to the unskilled labor Applications Used in the tracking of language and monitoring of health history of patients by hospitals (Weber, 2010). Video tracking Advantages There is shorter matching time which is as a result of good detection rate especially in the target detection It addresses on object tracking as well appearance change Disadvantages There are various hardware and programs needed to obtain and process the data The capture system may have specific requisitions for space to which it is being operated. The privacy issues in IoT are that there too much data to secure. The amount of information that the IoT devices can generate is staggering (Kumar, Patel, 2014). Another issue is that of the unwanted public profile; the company can use the collected data that consumers give willingly, analyze it and make decisions based on it (Wang Zhang, 2012). There is also the issue of hackers who can hack the systems and access the collected data. The security issue is based on public perception. The problem of hacking is a primary concern as researchers have been able to hack into real market devices with much energy and time (Dabbagh Rayes, 2017). Another issue is the actual security aspect. Securing the IoT devices carries more weight than securing the actual devices (Yang, 2014). Total time taken is 2+12+3= 17ms Changes after 1 s Therefore; 60ms is equivalent to 1 sec 17ms will equal how many seconds 17/60=0.28 Thus 1-0.28=0.72 s Time saved 0.72s The Nielson's law states that the high-end user's connection speed can grow up by 50% per year. This law of the broadband connectivity carries with it Moore's law of computer processing for some strange reasons (Stankovic, 2014). Nielson's observations were based on Moore's law that often mentioned view to which computers can be double every 18 months. His law relates to Moore's law in that the comment states that computers double every 18 months which corresponds to 60% per year. Moore's law for the network speed, the bandwidth grows slower than the computer's power because internet bandwidth is more of business realities than technological limits (Tan Wang, 2010). The implication of IoT is that there is a huge spread of the adaptation of IoT devices and other product that will utilize the same broadband connection and the technology will be availed for Nielson's law.
