The design of an automated external defibrillator Essay

The design of an automated external defibrillator - Essay ExampleAs such, this paper seeks to play up the defibrillator in relation to the history, functional components and human engineering considerations. Defibrillators join Kingdom is faced with health crisis with the spunky incidences of heart attacks among its citizens. These indices are reportedly some of the highest in the world with cardiovascular diseases causing more deaths every year than any other disease or condition. It is estimated that of the 150,000 people who have heart attacks annually, 94,000 of them die owing to non-homogeneous variables (Handler and Coghlan 2008). Research indicates that over one million people over the age of 35 in the United Kingdom have suffered a heart attack, and a third of these victim die before get to the hospital. The scale of the burden is felt in the economy with escalating costs of health care as indicated by the billions spent annually by the UK government on cardiovascular d iseases (Handler and Coghlan 2008). The relatively high incidences of heart attacks in UK are of great concern to health care professionals and other stakeholders, which have seen them, consolidate their efforts in enunciate to reduce the effects. Stakeholders such as medical exam engineers and manufacturers team up with healthcare professionals in an effort to sixth sense on the possible solutions in line with technological advances. This front has seen the successful adoption and incorporation of engineering in healthcare facilities in form of medical devices. According to the European Union definition, a medical device is an apparatus or instrument that is designed for preventative, diagnostic, monitoring, or therapeutic purposes and its purpose is not achieved by means of pharmacological, immunological or metabolic means (Krutmann 2011). Similarly, the mode of action of medical devices is not by dint of chemical substance action in a patients body, although may be assisted in its functions through such means. As such, it is essential that medical devices exceed the threshold under the European Union regulations, which cover for detailed records of the products, designing and construction is limited to qualified personnel, and comprehensive risk assessment should be through (Jacobson and Murray 2007). The key function of a medical device can be illustrated from scientific information quoted by the manufacturer in line with functional principle and the manufacturers labelling. Medical devices vary in their capacity and level of sophistication ranging from tongue depressors to haemodialysis equipment. Owing to the role played by medical devices in the provision of healthcare services, it is critical that appropriate guidelines and regulations are adhered to (Kramer, Xu and Kesselheim, 2012). It is for this reason that biomedical engineering move in to fill embark on the key aspects of medical devices that involve initial designing, system summary and practical application to ensure quality and efficient products. Among the medical devices are defibrillators, which play a critical role in the relieving heart attacks in areas away from medical facilities. This paper seeks to highlight defibrillators as a medical device while focussing on their history, scope of application and safety aspects of the device with require to human factors engineering. Fibrillation is characterised by accelerated and irregular contraction of heart muscle fibres, which is attributed to a deranged galvanizing activity of the heart. Fibrillation
