Bjork-Shiley Heart Valve Ethics Response

Ethics are defined as rules or standards governing the conduct of a person or the members
of a profession. In the medical field, practices and procedures are monitored for ethical
appropriation at all times. Ethics in the medical field in many cases have helped to
harness the dangerous powers of the field, ensuring that the powers are not abused, and
have also in many cases hindered technological advancements in the field.

The Bjork-Shiley Convexo-Concave mechanical prosthetic heart valve killed 400 out of
86,000 patients. One person dying out of 215 is not a statistic that the medical field
would consider ethical by any means. The heart valve was undertested and unregulated
before it was used on these 86,000 patients. Shiley used a ?earn as you learn? approach
to his marketing of this valve. There was a lack of communication between Shiley and the
FDA as he somehow got the prosthetic valve approved for patient use in 1979.

Every year, there are around 60,000 Americans who seek to replace their faulty heart
valves. This high demand made the faulty prosthetic valve very dangerous. Shiley did not
inform patients even until the early 90?s of the valve?s tendency to fail. Shiley got
quick, 6-month approval of the valve, without extensive and proper testing. Also, when

  • D Caries
    D Caries Introduction Caries have been a constant nuisance to humans, decaying teeth can become a major problem for those affected. It is certainly not the oldest pathology, nor the one of the greatest prevalence throughout humankind, but the information that can be extrapolate from such pathologies is great. The aim of this paper is to outline the pathology of caries and the influence that these have had on the human populations affected. Caries or caries dentium is the common name for tooth de

    positive effects of gene altering The Positive Effects of Gene Altering Since the beginning of the human race, we have been looking. We have been looking for ways to make our lives healthier, more comfortable, and happier. In the beginning it was simple rocks, plants, and fires. As our technology advanced so did the comfort of our lives. The wheel, the cure to the plaque, and who can forget the remote control, were all tools that made it possible to improve the quality of life. What tool lies ah
  • Barbie
    Barbie Since the beginning of time, toys have often been an indicator of the way a society behaves, and how they interact with their children. For example, in ancient Greece, artifacts recovered there testify that children were simply not given toys to play with as in the modern world. The cruel ritual of leaving a sick child on a hillside for dead, seems to indicate a lack of attention to the young (Lord 16). The same is true of today’s society. As you can see with the number of toy stores in
  • Lumbar disc problems
    lumbar disc problems Summary The lumbar region of the human spine is a location that is very susceptible to injury and trauma. A majority of the population experience back pain at some time during their life, and although in most cases the pain subsides after a time of rest, there is an enormous need for treatment of this malady. The various types of treatment for lumbar disc herniations include a more conservative method of rest, physical therapy, and anti-inflammatory or non-steroidal drugs.
  • Constantine Brancusi
    Constantine Brancusi Constantine Brancusi I found it very difficult to find information on Constantine Brancusi in hard copy, therefore, you will see at the end of my paper that all of my sources are websites. The little information I did locate on the artist was very, very little. Therefore, I combined the small amount of information with some research I found on artists that were strongly influenced by Brancusi. Brancusi\'s imprint on contemporary sculptural practice ranges from the dissemina
  • Amputee Fittness
    Amputee Fittness The new advancements in prosthetics have allowed amputees and people born without limbs to participate in many activities. In order to keep fit and at an optimum weight amputees need to exercise. With prosthetics they can do many exercises as normal people. Training on a treadmill is a way for them to keep the cardiovascular system. This way can keep aerobic fitness where the heart and lungs are healthy. Also good for aerobic health, is stationary rowing which can be easily done
  • Biomechanics
    Biomechanics The term biomechanics means the study of the structure and function of biological systems using the methods of mechanics. Biomechanics studies the process of kinematics and develops artificial limbs and footwear specifically to aid the body in performance. The study of biomechanics also includes the stress testing on crash dummies in car accidents and any sport where stress is placed on the body in order to produce performance. The type of stress specifically is the joint stimulatio

  • Prosthetics
    Prosthetics Introduction Prosthetics is the branch of surgery dealing with mechanical devices used to reproduce the form and function of missing body parts. Prosthetics is the replacement of faulty or amputated body parts with artificial body parts. Artificial limbs have been in use since at least 300 BC. In AD 1509 German knight, Gotz von Berlichingen, called Gotz of the Iron Hand, wore an artificial hand with jointed fingers. Early in the 19th century a German prosthesist built a hand with fin

The human body is the physical manifestation of this represented self and is interpreted by the observer depending on its gender, age, colour, attractiveness, adornment and perceived disabilities (these perceptions often being culture-bound as well). In addition to this, the performer uses ma
