Comparative Evaluation of Body Temperature Measurement Using the CardioWatch 287-2 in an Intensive Care Setting.

Temperature readings from wearable Cardiowatch BT sensor, wearable Radius-T BT sensor, tympanic temperature and rectal temperature will be collected. Each participant will remain in the study as long as the rectal temperature is measured with a maximum of 24 hours. Other than the wearable Cardiowatch, the Radius-T sensors, and the rectal thermometer no additional interventions will take place due to the study. Temperature monitoring of patients will be performed according to hospitals routine care and will not be affected by the study. Patients may receive additional treatment to ensure best care.
