Validation of the Measurement Accuracy of the Tcore Thermometer

The aim of the study conducted at the UKSH is to investigate the measuring accuracy of the body core temperature thermometer Tcore®. Therefore the bias of the measurements to the reference measurements of the bladder catheter thermometer is determined. Patients included are in the ICU of the UKSH and awake. They already have the reference thermometer in the catheter. The patient investigation time is limited to maximum 2 hours, SAEs will be recorded for 24 hours. The temperature of the two temperature sensors will be compared on three timepoints.
