More than a million times each year in hospitals all around the world, a device called the heart-lung machine keeps patients alive while surgeons repair damaged hearts in an unobstructed "dry environment." Those who benefit range from tiny babies with congenital defects to adults suffering from arterial blockage. For many years, Richard Griewski has led the design efforts on the 3M Sarns brand of heart-lung pumping systems, one of the oldest and most respected names in this life-sustaining technology. Griewski has played a particularly important role in pioneering the first computer-aided centralized monitoring systems for heart-lung machines. In the process, he has had to learn the fundamentals of cardiac surgery to address the human factors needs of the perfusionists who operate this equipment during critical moments. His engineering expertise also includes: pumping systems, cell biology, display systems, electronics, software, and electromagnetic compatibility. One veteran perfusionist at the famed Texas Heart Institute calls the Sarns devices the "Coca Cola" of the field, based on the machines' long track record for reliability, as well as such innovations as automatic battery backup, integrated gas mixer, and "splash-proof" design.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
Two issues have been the bane of the plastics industry for as long as one can remember: The ban on plastic grocery bags and whether the use of bisphenol A (BPA) in plastics such as polycarbonate and PVC is harmful to humans.
One expects to see outlandish apparel at major global fashion events, but New York Fashion Week may have outdone itself, and set a new bar for Paris and Milan, when it put an Ebola jumpsuit in the spotlight.
