The continuing development and manufacture of infrared devices, together with improvements in thermal body mapping techniques have simplified surface skin thermography which is being used more extensively than ever before. Normative thermography data, however, remains incomplete. A normative blood redistribution range of skin temperatures was established for use as a reference for laboratory infrared thermography (IT), thermal body mapping, and mass fever screenings. 500 healthy volunteers participated in this prospective study. To determine the maximum range of the skin temperature changes due to the posture-related physiological blood redistribution, the volunteers were asked to keep one extremity up and another extremity down whilst lying, sitting, and standing. We obtained 6000 hand and 400 foot temperature readings. The normal temperature was 29.1 ± 0.6 °C for the middle fingers and 27.8 ± 0.7 °C for the toes. The physiological temperature change during body position changes ranged from 4 to 6 °C (fingers: 27-31 °C; toes: 26-32 °C). At normal room temperature, the surface skin temperature may vary within this range due to blood redistribution. These changes reflect the individual variability of vasomotor activity. This physiological range of temperatures should be taken into account during IT and other thermography-involved investigations.
红外设备的持续研发与制造，以及热体成像技术的改进，简化了体表皮肤热成像技术，该技术的应用比以往任何时候都更加广泛。然而，热成像的标准数据仍然不完整。建立了皮肤温度的标准血液再分布范围，作为实验室红外热成像（IT）、热体成像和大规模发热筛查的参考。500名健康志愿者参与了这项前瞻性研究。为了确定因姿势相关的生理性血液再分布导致的皮肤温度变化的最大范围，志愿者们在躺卧、坐着和站立时被要求一只肢体向上，另一只肢体向下。我们获得了6000次手部和400次足部的温度读数。中指的正常温度为29.1±0.6°C，脚趾的正常温度为27.8±0.7°C。体位改变期间的生理性温度变化范围为4至6°C（手指：27 - 31°C；脚趾：26 - 32°C）。在正常室温下，由于血液再分布，体表皮肤温度可能在这个范围内变化。这些变化反映了血管舒缩活动的个体差异。在IT及其他涉及热成像的检查中，应考虑这个生理温度范围。
