What is an example of a medical error involving equipment failure?

One example of a medical equipment failure leading to a medical error is the case of the Therac-25 radiation therapy machine. This event, which occurred in the 1980s, resulted in several patient overdoses and deaths due to software errors in the machine. The Therac-25 failed to correctly calculate and deliver radiation doses, leading to severe patient harm. The software flaws went undetected due to insufficient peer review and inadequate testing of the machine before it was released for patient use.
