Technology 1992-medical electronics

Advances of note during 1991 are reviewed. A microprocessor-based fiber-optic sensing system that monitors blood gas in real time was introduced. Also introduced was a tympanic or ear thermometer that measures infrared heat generated by the eardrum and surrounding tissue and displays the temperature in about 2 s. Interest in artificial heart research was reviewed. Images of the human brain as it performed the simple task of recalling a word showed that the recall process was going on in unexpected parts of the brain, not just in the hippocampus.<
