The 3M™ SpotOn™ system is a non-invasive, accurate core temperature monitoring system that continuously measures patient temperature with an affordable single-use sensor. A single-use sensor is placed on the patient's forehead before surgery and is worn throughout the perioperative journey. The temperature is always displayed. A memory chip within the sensor allows a two hour continuous visual representation of the patient temperature trend on the control unit. The sensor stays on the patient, as it is disconnected from the sensor cable and reconnected at each point of care, eliminating the variability associated with clinician technique and use of multiple monitoring devices.
