Heart surgery is a process that some people must face, whether it is family members or them personally having the surgery and is better living through science for our society because of the many changes it has made over the years. There have been many changes in the scope of heart surgery and transplants, one major change that has helped is the Heart Lung Bypass Machine, it keeps the heart beating while doing any kind of heart surgery. This keeps the patient alive while the doctors are able to work on the vital organ. Heart surgery is a risky procedure that can greatly increase the life of the patient, and it can also end life quickly; though it is a necessary risk. This procedure is something that should be viewed as a good thing of science and better living because of all of the help that it has given to people who have had it and successfully completed all recovery processes that went on to live healthier and longer lives.
One way heart surgery is better living through science for our society is with the invention of a mechanical, temporary heart in the 1950’s; the IVOX was invented to save the lives of people with lung disease. The IVOX was also used to replace the ECMO. Georg Matheis, writer for Perfusion, states in his article “New Technologies for respiratory assist” that the IVOX is surgically implanted into a patient and is used to exchange gases within the body. The IVOX operates off of a small pump, which exchanges gases in the patient’s near dead lungs (Matheis). This led to the invention of the IMO, which uses a balloon to help exchange oxygen at a better and faster rate than before (Matheis). This IMO allowed a higher survivability in patients with lung disease. The death sentence that certain lung disease would...

Stephanie Lee MS in Medical Device Innovation Personal Statement This past January, I had the most enriching opportunity to dissect and study the thoracic cavity of a human cadaver through the Advanced Cardiac Anatomy course held by the UMN. For the first time, I held a human heart within my hands, studied its anatomy, and was also able to closely examine the placement of a dual-chamber defibrillator. My company, Heraeus Medical Components, specializes in products for cardiac rhythm/heart failure management, so this was extra meaningful for me to not only see the leads, but also follow them to the sites of therapy within the heart. In a room of twenty-four cadavers, could I have somehow impacted any one of these patients’ lives?
Brendan Maher, in his article “How to Build a Heart” discusses doctor’s and engineer’s research and experimentation into the field of regenerative medicine. Maher talks about several different researchers in this fields. One is Doris Taylor, the director of regenerative medicine at the Texas Heart Institute in Houston. Her job includes harvesting organs such as hearts and lungs and re-engineering them starting with the cells. She attempts to bring the back to life in order to be used for people who are on transplant waiting lists. She hopes to be able to make the number of people waiting for transplants diminish with her research but it is a very difficult process. Maher says that researchers have had some successes when it comes to rebuilding organs but only with simples ones such as a bladder. A heart is much more complicated and requires many more cells to do all the functions it needs to. New organs have to be able to do several things in order for them to be used in humans that are still alive. They need to be sterile, able to grow, able to repair themselves, and work. Taylor has led some of the first successful experiments to build rat hearts and is hopeful of a good outcome with tissue rebuilding and engineering. Scientists have been able to make beating heart cells in a petri dish but the main issue now is developing a scaffold for these cells so that they can form in three dimension. Harold Ott, a surgeon from Massachusetts General Hospital and studied under Taylor, has a method that he developed while training. Detergent is pumped into a glass chamber where a heart is suspended and this detergent strips away everything except a layer of collagen, laminins, and other proteins. The hard part according to Ott is making s...

Gastric bypass is life changing procedure that is not to be taken lightly by any means.
What I wanted to talk about today is this life save device called a automated external defibrillator. It has become the number one way to resuscitate a person who has had a cardiac arrest unwitnessed by emergency medical services and who is still in persistent ventricular fibrillation or ventricular tachycardia. Many people have played a big role in creating this device to become more efficient, smaller and easier to use for the general public. Here are just to name a few that played a part in the creation for this device: Claude Beck, James Rand, Paul Zoll, and Frank Pantridge. The first use of a defibrillator on a patient was in 1947 on a 14 year old boy. Claude Beck was performing a open-chest surgery when the boy went into fibrillation. Beck manually massaged his heart for 45 minutes until the arrival of the defibrillator. The defibrillator he used during surgery was made by James Rand and had silver paddles the size of large teaspoons. In 1956, Paul Zoll performed the first successful external defibrillation with a more powerful defibrillator. A major breakthrough in emergency medicine occur in 1965. At the time a majority of coronary deaths occurred outside of the hospital setting since defibrillator required a main power source and were only available in hospitals it made them pretty much useless in saving lives outside of a hospital setting. Frank Pantridge often referred to as the Father of Emergency Medicine, made the first portable defibrillator in 1965. This device was power by a car battery and weighted approximately 70 kg (155 lbs). By 1968 he was able to create a defibrillator that was safer to use and only weighted 3 kg (6-7 lbs). It was argued that their was a possibility of misuse of the device if given to a unt...

Coronary artery bypass graft surgery is a procedure that can be life-saving for patients with heart disease, but it also carries risks after the procedure that can impact patient outcomes negatively. Because over 395,000 Americans have CABG surgery each year, and the risk-adjusted mortality rate for patients is 2%, according to Centers for Disease Control (CDC) statistics, health care professionals must find ways of reducing risks and complications to improve the outcomes for many patients (Ferguson, 2012). Heart disease is often comorbid with other conditions, like lung disease, peripheral arterial disease, hypertension, and diabetes, which can raise the risk of complications (Ferguson, 2012; Nejati-Namin, Ataie-Jafari, Amirkalali, Hosseini, Sheik Hathollahi, & Najafi, 2013). Complications that can arise following surgery include atrial fibrillation, prolonged inflammatory reactions, a build up of fluid near the heart, accelerated atherosclerosis, and nearby vein or artery blockage (Gokalp, Ilhan, Gurbuz, Cetin, Kocaman, Erdogan, & … Satiroglu, 2013; Ferguson, 2012; Scheiber-Camoretti, Mehrotra, Ling, Raman, Beshai, & Bowman, 2013; Sicaja, Starcevic, Sebetic, Raguz, & Vuksanovic, 2013). These complications can lead to increased lengths of stay, increased readmission rates, risk of further complications, failure of the bypass graft, cognitive dysfunction and memory loss, patient suffering, and even death (Ferguson, 2012; Gokalp et al., 2013; Sicaja et al., 2013). In turn, nurses, other care providers, and institutions may face negative consequences themselves, including a risk of lawsuits, increased employee workload, higher per-patient costs, reduced or withheld private insurance, Medicaid, and Medicare reimbursements, auditing...
Some of the daily preparations that are performed by a perfusionist would consist of reading through a patient’s records to check out the patients history, family history, laboratory tests, cardiology reports and so on. Following this the heart and lung machine needs to be inspected and tested to make sure that it is in proper working order and that the disposables that are used are properly loaded and functional. Next the perfusionist needs to discuss with the surgeon what the needs of the patient may be and also what the needs of the surgeon may be. The perfusionist does this in order to use the correct disposables and correct pump to meet both the demands of the patient and that of the surgeon.
The author states “the effort to suppress scientific information reflects a dangerously outdated attitude.” Donahue supports this claim by explaining several cases in science where sharing information on microbiological studies has helped science move forward. The author mentions an article that was published describing how susceptible the United States milk supply is to the botulinum toxin. This article was suspended by the National Academy of Science because they believed it to be a “road map for terrorists” (p. 1). The author believes, however, that instead of censoring such an article, this information should be shared, this way other scientists will be able to discover ways to defend against terrorist attacks.
One of the common diseases in the respiratory system that many people around the world face is emphysema or also known as chronic obstructive pulmonary disease (COPD). It is a chronic lung condition where the alveoli or air sacs may be damaged or enlarged resulting in short of breath (Mayo Clinic, 2011). If emphysema is left untreated, it will worsen causing the sphere shaped air sacs to come together making holes and reduce the surface area of the lungs and the amount of oxygen that travels through the bloodstream, blocking the airways of the lungs (Karriem- Norwood, 2012). The most common ways a patient can get emphysema are by cigarette smoking or being exposed to chemicals, dust or air pollutants for a long period of time. Common physical exams reveal a temperature of 100.8 Fahrenheit, 104 beats per minute, a blood pressure of 146/92, and a respiratory rate of 36 breaths per min (Karriem- Norwood, 2012). (see appendix A.1,A.2, A.3, A.4 for complete proof.)
The primary concern for Mr. Miller would be preventing further ischemia and necrosis of the myocardial tissues, preventing serious complications such as cardiac dysrhythmias and heart failure, as well as relieving his chest pain that radiates to his left arm. Preventing further ischemia and necrosis of the myocardial tissue will help prevent the development of heart failure due to myocardial infarction, whereas relieving his pain will help reduce his episodes of shortness of breath, and will also help to reduce any anxiety and restlessness he may be having from being in pain and short of breath.

Medical Ventilator is a machine that mechanically moves air in and out of the lungs. It always be used to provide breathe for a patient who is physically unable to breathe, or breathing insufficiently. This is because this machine is able to help raise the oxygen level for these patients, and also to improve the ventilation, improve the ventilation function and reduce power consumption and save breath cardiac reserve capacity.
