Digitized Infrared Segmental Thermometry: Time Requirements for Stable Recordings

The daily average core temperature (rectal on the left [A and C] and tympanic on the right [B and D]) for 17 subjects during the 30-minute recording session. The black box represents the 5- to 15-minute time interval for the Th stable trend. The gray block represents the 20- to 24-minute time interval for the IRC recording.

The average SST temperature (for each site: IRCL4l, IRCL4R, IRCC4L, IRCC4R) for 17 subjects for each day during the 20- to 24-minute recording interval.

A, The average Th SST (for each site: ThL4l, ThL4R, ThC4L, and ThC4R) for 17 subjects all 5 days combined during the entire recording period; the insert represents the same description on a smaller temperature scale. B, The average IRC SST (for each site IRCL4l, IRCL4R, IRCC4L, and IRCC4R) for 17 subjects all 5 days combined during the 20- to 24-minute interval.

The daily average SST temperatures (for each site: [A] ThC4L, [B] ThC4R, [C] ThL4l, and [D] ThL4R) for 17 subjects during the 30-minute recording session. The black box represents the 5- to 15-minute time interval for the Th stable trend. The gray block represents the 20- to 24-minute time interval for the IRC recording.

The daily average SST temperatures (for each site: [A] ThC4L, [B] ThC4R, [C] ThL4l, and [D] ThL4R) for 17 subjects during the interval of 4 to 16 minutes. Also note the smaller temperature scale (84°F-94°F).

The average temperature and relative humidity (%) for 17 subjects for the daily recordings.

The comfort range for core and SST temperatures with Th and IRC. Dashed lines represent the range of the comfort zones as calculated from McArdle et al ¹⁶.
