Ethics: Deactivating a Cardiac Pacemaker: Is it Ethical? This paper will address the ethical dilemma of deactivating a cardiac pacemaker. While this issue seems ethically simple, it is in practice, incredibly complex in its ethical ramification. This paper will attempt to chart out these ethical implications particularly as they pertain to nursing. While it is not necessary to look at the precise mechanics of a pacemaker, it must be understood, first, that a pacemaker is an electronic device that
conditions such as ulcers, traumatic or burn wounds, osteoarthritis, and cancer. Electrical stimulation is simply the application of electrical pulses to the body, whether it is for function or therapy. The classical and common example is that of the cardiac pacemaker. The range of clinical uses of electrical stimulation has and is growing wider and includes: pain relief (often known as TENS - Transcutaneous Electrical Nerve Stimulation), maintaining or increasing range of movement, muscle strengthening, facilitation

automobile, and the television. Almost every device has some type of computer in it. Whether it is a cell phone, a calculator, or a vending machine. Even things that we take for granted most cars since the 1980’s have a computer in it or a pacemaker. All of the advancements in computers and technology have led up to the 21st century in which “the greatest advances in computer technology will occur…” Mainly in areas such as “hardware, software, communications and networks, mobile and wireless
technology in their daily lives. Although it can be abused in many ways, technology used properly is a tool that aids in education, health and communication. Our physical health has benefited greatly from technology. Through inventions like the pacemaker and artificial limbs, a tremendous amount or people have had better physical conditions. This biological technology is not favorable to all. Some say that it is better for nature to do its work and people should not interfere. The spread of new inventions
condition, she wouldn’t live past the age of six. She was also partially blind in her left eye, which restricted her from driving. As she got older and older, her heart grew weaker and weaker. At the age of 35 years old, she had a pacemaker surgically implanted in her chest. A pacemaker is a battery-powered case that assists the heart in beating. An incision is made and a pocket is formed in the area overlying the muscle on the outside of the chest wall. “Most are placed to prevent the heart from going to
patients who have pacemakers will need an MRI during their life time.”(3) However, there are many risks for MRI scans on patients with pacemakers. What are the risks? And do the benefits outweigh the risks? I will explain to you what an MRI is and what they are used for. After I inform you on what are MRIs, I will explain the risks and benefits of the scans on pacemaker patients. Finally I will explain some ways to reduce the risks of the procedure for patients with pacemakers. MRI stands for Magnetic
inventions like the Pacemaker and Java - computer language - were the power of Canada that defined and advanced the Canadian medical and computer fields. Another Canadian technological innovation, the Blackberry in 1999 enriched the economic, job and mobile sector making Canada an economic hub. These technological innovations advanced human index parameters, gaining Canada recognition from around the world. In the early 1950s, the first ever amazing invention of an external cardiac Pacemaker was developed
Although not as strictly addressed, there is still a schism when it comes to the matters of experimentation involving animals. Those in opposition of it see it as being against the will of the animal, because animals have no say in the matter. However, through animal experimentation there has been vast medical advances in hospitals and veterinarians , research has led to cures for various diseases that would normally take many more years to cure, and the use of animals is highly ethical considering
Lab Report The Effects of Drugs on Cardiac Physiology The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside
cardiologists can insert pacemakers which are artificial devices that are placed near the heart inside patients for stimulating the heart muscle and regulating its contractions. In addition, cardiologists can insert stents which are tubular supports placed temporarily inside a blood vessel, canal, or duct to aid healing or relieve an obstruction. What they can also do is that they check up on the patients that need the most help and they can sometimes make CT scans or CMRI’s ( Cardiac Magnetic Resonance
might be pregnant is very critical, but in some cases, MRI could be performed safely late in a pregnancy the doctor needs to check the woman’s abdominal area or her baby. Some medical devices are not be safe to be used with an MRI, such as a cardiac pacemaker, a specific type of vascular stent, and inner ear implants (Robinson, 2012). Furthermore, metal objects within the body can also cause problems with the MRI. For example, objects such as watches, jewelry, pants, and eyeglasses are not allowed
leading to paralysis. Acute and subchronic oral doses of barium cause vomiting and diarrhea, followed by decreased heart rate and elevated blood pressure. Higher doses result in cardiac irregularities, weakness, tremors, anxiety, and dyspnea. A drop in serum potassium may account for some of the symptoms. Death can occur from cardiac and respiratory failure. Acute doses around 0.8 grams can be fatal to humans. Barium nitrate makes signal flares burn with a green flame. Barium ferrite is used to make magnets
Inventions and Discoveries of the 1960’s The 1960’s era was a time period notorious for its technology and innovation. This particular era of time was booming with creativity. People started to venture outside of the traditional mindset established by their elders, and the new generation made a great impact on the American lifestyle. The original models of these creations have been modified into complex designs, yet as we strive for perfection, we still use these revolutionary concepts. Like
cardiovascular diseases (Hjärt-Lungfonden, 2008) and today 40 000 of the Swedish population have a pacemaker. (CISIONWIRE, 2008) A treatment for a heart that is beating too slowly is receiving a pacemaker which keeps the heartbeat regular. (Hjärt-Lungfonden, 2008(2) The pacemaker system is divided into 2 parts and it is placed underneath the skin below the clavicle. The first part is the pacemaker itself, which is like a computer with batteries. Second part is the electrodes that with the help
the bolus travels into the pharynx, where the epiglottis closes off the top of the trachea so no food can enter. Then it moves on to the esophagus, where peristaltic waves push the food toward the stomach. The food enters the stomach through the cardiac sphincter at the end of the esophagus. Now the Cheetos have entered the stomach. The process of breaking down carbohydrates has already begun in the mouth and now more chemical and mechanical digestion will take place in the stomach. Once the
blood pressure (BP), and oximetery measurements provide better insight into the inner workings of the human body. In using the results of the assessment, one can determine the affects that rest and exercise have on the cardiac system. Heart rate is described as the rate of the cardiac cycle. Heart rate is measured in beats per minute (bpm). A well conditioned heart is able to pump large amounts of blood with each beat. This is called bradycardia (* 60 bpm). In contrast, a poorly conditioned heart
forces to include increased competition, regulations and product control, and the rapid pace of pacemaker technology in the overall market. Furthermore, Medtronic itself suffered from internal departure of workers (forming new rapid competition/startups), failure in product development (lack of new value and differentiation), and disaster in two major lines of pacemakers. Spin-off and copied pacemaker design and tech pushed out Medtronic’s market position and allowed early adapters and late followers
support cryoablation and its development of the Freezor Cardiac CryoAblation Catheter demonstrates that it continues to improve its technology to provide the best patient care. The Freezor Cardiac CryoAblation Catheter is primarily indicated for paroxysmal atrial fibrillations, specifically atrioventricular nodal reentrant tachycardia (AVNRT), and it provides a number of advantages over the current standard of care. Cryoablation with the Freezor Cardiac CryoAblation Catheter eliminates complications associated
the body temperature. Human body would not able to move at all without muscles. In human body there are more than 600 muscles and most of the muscles attached to the skeleton. Muscle system can be divided into three types of muscles which is the cardiac muscle, skeletal muscle and also smooth muscle. There are two type of muscle arrangement which is the antagonistic muscles and synergistic muscles. The only voluntary muscle tissue in
