According to the researches led by Mayo Clinic it’s now evident that calls made on cell phones do not affect hospital medical devices. However, store anti-theft alarms can cause implanted heart devices fail to work properly. The tests proved that ordinary use of cell phones caused no interference with patient care equipment. There were two cell phones used in the study that were using different technologies from different carriers, as well as 192 medical devices. During a five-month period in 2006 there were performed over three hundred tests were without a single problem.
Everything is good with phone but as soon as it appeared to be a portable CD player the things changed dramatically and a CD caused an abnormal electrocardiographic reading when a patient used it near one of the leads of the device. As soon as the player was turned off the device went on working properly.
John Abenstein, M.D., of Mayo Clinic's Department of Anesthesiology reports that risk of some technological devices upsetting the function of patient care equipment in hospitals appears to be small. There is a necessity that the Food and Drug Administration should make some more detailed analyses in order that health care facility policies can be altered when appropriate.
