Abstract
A probe for obtaining temperature and humidity readings within the oral and nasal cavity. An elongated tube having a wire cage at one of its ends, includes first and second longitudinally positioned pairs of thermocouples, one thermocouple of each pair having a wetted wick for obtaining humidity measurements. The pairs of thermocouples are positioned within the confines of the wire cage such that temperature and humidity measurements are made of the subject's airway. Other longitudinally positioned thermocouples are outside the confines of the wire cage and are used to obtain surface temperature readings. For positioning inside the relatively small nasal cavity, one embodiment is constructed and arranged to reduce the outside dimension of the cage for ease of insertion and to return it to its original dimension after insertion, so that the thermocouples outside the confines of the wire cage can contact the nasal membrane.
