Summary
Accurate digitized infrared segmental thermometry (DIST) requires patients to acclimatize for at least 8 minutes in a controlled environment. This ensures stable skin surface body temperature readings for reliable DIST measurements.
Area of Science:
- Biomedical Engineering
- Medical Physics
Background:
- Digitized infrared segmental thermometry (DIST) measures skin surface body temperature.
- Determining optimal acclimatization times is crucial for accurate DIST readings.
Purpose of the Study:
- To evaluate the necessary acclimatization duration for stable DIST measurements.
- To establish core body temperature acclimatization trends in a controlled setting.
Main Methods:
- Seventeen subjects underwent a 20-minute acclimatization period in a temperature-controlled room.
- Bilateral DIST temperatures were measured using thermistors and infrared cameras (IRCs) at C4 and L4 levels.
- Temperature data was recorded after a 20-minute stabilization period, with continuous monitoring for 30 minutes over 5 days.
Main Results:
- Thermistor recordings showed stabilization trends between 8 and 16 minutes.
- Infrared camera (IRC) trends were also conclusive for core temperature requirements.
Conclusions:
- A minimum 8-minute acclimatization period in a controlled environment is recommended for accurate DIST readings.
- An 8-minute maximum recording period with the patient prone is suggested for optimal results.
