Patient Monitoring Sensors | Clinical Thermometry

Thermometrics Biomedical Chip Thermistor Assemblies are designed for use in applications involving both intermittent and continuous patient temperature monitoring. Repeatability and fast response are essential, not only for the intermittent temperature requirements associated with oral and rectal fever measurements, but also for the continuous monitoring often necessary during induced-hypothermia and general anesthesia, or when employed in the care of infants and premature babies. Intensive care units, along with recovery rooms, have also adopted patient temperature as part of their vital sign monitoring procedures. Temperature monitoring for skin surface, tympanic, esophageal, foley catheters, and biofeedback applications has also improved due to the high stability and tight interchangeable tolerances designed into each Thermometrics’ Biomedical Sensor Assembly.
