Abstract: The invention relates to a patient cable for medical measurements performed in connection with Magnetic Resonance Imaging (MRI). In order to eliminate the risk of thermal injuries without compromising the signal-to-noise ratio more than what is required for patient safety, the patient cable comprises two successive cable elements having different resistance characteristics. The second cable element, which is connected by the first cable element to the patient, has a total resistance increased from a normal high-conductivity resistance value of a patient cable to suppress antenna resonances in the second cable element. The first cable element, which is connected to the electrodes on the skin of the patient, has a total resistance substantially greater than that of the second cable element to prevent electromagnetically induced currents from flowing to the patient and to prevent excessive heating of the cable by electromagnetic induction.

Abstract: Arrangement in connection with a patient circuit and an absorber means. The arrangement comprises an information transfer means and an electronic means and a transponder electronically programmed with desired information. The transponder is attached to the absorber means. The information transfer means is arranged to communicate with the transponder, and the electronic means is arranged to carry out desired procedures from the basis of the information obtained from the anaesthesia/ventilation system and via the information transfer means from the transponder attached to the absorber means.

Abstract: The invention relates to an arrangement for monitoring of a patient comprising one or several sensors for patient connection, a patient transceiver device and a transfer system, which is capable to transfer data between the sensors and the patient transceiver device, the arrangement further comprising a base station/monitor transceiver device at least to receive data sent by the patient transceiver device, and a battery device to act as a power source for the arrangement. The battery device (11) is attached into one of the sensors (9).
