可靠的连续核心温度测量对于监测患者非常重要。零热流方法（ZHF）可以潜在地满足当前测量方法所缺乏的非侵入性、可靠性和短延迟时间的要求。本研究的目的是确定前额上新ZHF器械在这些问题上的性能。七名健康受试者在35 °C和50%相对湿度的环境条件下进行10分钟休息、30分钟次极量运动（平均温度升高约1.5 °C）和10分钟被动恢复的方案。将ZHF温度（Tzhf）与食管（Tes）和直肠（Tre）温度进行比较。ΔTzhf-Tes的平均偏差±标准差在休息时为0.17 ± 0.19 °C，运动时为−0.05 ± 0.18 °C，恢复时为−0.01 ± 0.20 °C，后两者不显著。95%的一致性范围为-0.40至0.40 °C，Tzhf与Tes相比几乎没有任何延迟。当核心温度迅速变化时，Tre表现出明显的延迟和偏离Tes。结果表明，所研究的ZHF传感器在高温和稳定的环境条件下能够很好地跟踪Tes，可能是医院可靠的无创连续核心温度测量的一种有前途的替代方案。
Reliable continuous core temperature measurement is of major importance for monitoring patients. The zero heat flux method (ZHF) can potentially fulfil the requirements of non-invasiveness, reliability and short delay time that current measurement methods lack. The purpose of this study was to determine the performance of a new ZHF device on the forehead regarding these issues. Seven healthy subjects performed a protocol of 10 min rest, 30 min submaximal exercise (average temperature increase about 1.5 °C) and 10 min passive recovery in ambient conditions of 35 °C and 50% relative humidity. ZHF temperature (Tzhf) was compared to oesophageal (Tes) and rectal (Tre) temperature. ΔTzhf–Tes had an average bias ± standard deviation of 0.17 ± 0.19 °C in rest, −0.05 ± 0.18 °C during exercise and −0.01 ± 0.20 °C during recovery, the latter two being not significant. The 95% limits of agreement ranged from −0.40 to 0.40 °C and Tzhf had hardly any delay compared to Tes. Tre showed a substantial delay and deviation from Tes when core temperature changed rapidly. Results indicate that the studied ZHF sensor tracks Tes very well in hot and stable ambient conditions and may be a promising alternative for reliable non-invasive continuous core temperature measurement in hospital.
