Conditions

Validation measurement accuracy of a non-invasive in-ear sensor for body temperature, heart rate and oxygen saturation

Interventions

Group 1: The sensor is placed in the patients ear before surgery. Body temperature, heart rate and oxygen saturation are then measured during operation. The data are then compared with the records of

Design outcomes

Primary

Measure	Time frame
Is the non-invasive in-ear sensor able to measure heart rate, oxygen saturation, and body core temperature over a long-term period accurately compared to standard intraoperative measurement instruments (electrocardiography, bladder temperature measurement and pulse oximetry)?	—

Secondary

Measure	Time frame
Do kinematics of non-invasive in-ear sensor and standard intraoperative temperature measurement differ with regard to a change in the body temperature?	—
