Recall of AED

Nihon Kohden announced a recall of all AED units on November 20, 2009. AED is the abbreviation of Automated External Defibrillator, and it returns the heartbeat back to normal from ventricular fibrillation by defibrillation. Citizenry was able to use it from April, 2007. About 250000 AEDs were put in hospitals, ambulances, schools, public facilities, and so on, and Nihon Kohden represents about 50 percent of shares. The reason for the voluntary recall is a woman died because of trouble with an AED in April. In recent years, the number of such medical accidents creased due to medical machines. In my opinion, makers and engineers should check equipment more regularly for accidents not to happen. First, periodic inspections can prevent an accident discovering malfunctions early and service. Next when the malfunction is discovered measures can be taken for a malfunction not to happen again. Therefore, I think that service is important.
