Abstract
A temperature probe, such as for a respiratory system in which breathable gases are supplied to a patient, includes a housing having a cavity sized to snugly receive therein a generally cylindrical container within which is secured a thermistor, with the container adapted to provide a barrier to moisture. The probe provides a quick temperature response but minimizes migration of moisture to the thermistor notwithstanding the high temperature and heat levels encountered in normal operation of the respiratory system.
