G. Mark’s Answer
A clinical engineer is the person who builds and maintains and supports medical devices and services in the hospital. They can do research, evaluate medical statistics and device new machines and methods. As such, they might supervise the users of these machines and other medial equipment. They also will consult in the use, training and development of medical equipment. Doctors and nurses and other medical personnel will often consult with them, particularly in matters dealing with the intersection of medicine and engineering, like recommending uses for devices and other medical resources. They also will be familiar with IT and IT principle and equipment, since computers are such an integral part of hospital environments and processes and becoming moreso as time goes on.
To become a clinical engineer is pretty much like becoming other types of engineers, except that some specialized training like a BS in Healthcare Science, which is Clinical Engineering. Some background includes the typical Liberal Arts Sciences, Mathematics and Language courses, with an especially significant emphasis on the sciences. Eventually that student will seek certification by the Examination Certification for Clinical Engineering tests, followed by an oral examination. So if you want to get into this field, a BS is your first step.
