Abstract

An arrangement for patient monitoring. The arrangement includes at least one body sensor to detect a physiological parameter as body signal data and at least one of a body signal processing unit connected to the body sensor for processing body signal data, and a therapy device designed to act on the patient. In addition, the arrangement includes a monitoring center having a signal field strength evaluation means, a mobile phone terminal designed to transmit the data from at least one of the body signal processing unit and the therapy device to the monitoring center and from the monitoring center to the therapy device, and a cellular mobile phone network. The mobile phone terminal is operable in the cellular mobile phone network. The arrangement further includes a base station coordinate storage unit for storage of coordinate data and a mobile phone exchange linked to the base station coordinate storage unit for the reception of position data of the mobile phone terminal. The signal field strength evaluation means is utilized for evaluating signal field strength data reflecting the distance of the mobile phone terminal from at least one base station together with coordinate data of at least one active base station of the mobile phone network in order to determine the whereabouts of the patient.
