Abstract
Although the cellular phone shows the high diffusion rate, many hospitals are asking for turning of a subscriber uniformly. Since the information about electromagnetic interference (EMI) with medical electric devices, especially with artificial cardiac pacemakers is known widely, patients and visitors follow it. However, for patients admitted for medium to long periods of time, switching off their cellular phone means shutting down an important route of communication. Allowing cellular phone use is an easy way to reduce inpatient isolation stress. The request for permission of cellular phone use is strong from the viewpoint of patient service. In this paper, while the limit of the safety about use of a cellular phone is shown from the knowledge acquired until now, the notes, technique, procedure, and three examples on which cellular phone use is permitted in restricted area are shown. For safe use of mobile communications in medical institutions, we must solve the following problems.
(1) Prevention of EMI with medical electric devices by the electromagnetic waves emitted by cellular phones
(2) Prevention of noise caused by people talking on telephones
(3) Prevention of accidents caused by lack of at entiveness of operators of cellular phones
