Subjects were immersed for 10 min in water at 14.5 degrees C, after exposure either to ambient temperature or sauna heating. During the immersions, total ventilation, end-tidal PCO2, the mean of three surface skin temperatures, and deep skin temperatures were measured. There was a statistically significant correlation between the rate of change of deep skin temperature and the initial ventilatory responses evoked during both cold water immersions. After the sauna heating and cold water exposure, the temperature gradient through the skin appeared to be related to the ventilatory response. There was no significant correlation between the rate of change of mean surface skin temperature and the ventilatory response. The results suggest that the primary drive to increased ventilation during cold water immersion is the rate of change of deep skin temperature.
在暴露于环境温度或桑拿加热后，受试者在14.5摄氏度的水中浸泡10分钟。在浸泡过程中，测量了总通气量、呼气末二氧化碳分压、三个体表皮肤温度的平均值以及深部皮肤温度。在两次冷水浸泡期间，深部皮肤温度的变化率与最初诱发的通气反应之间存在统计学上的显著相关性。在桑拿加热和冷水暴露后，通过皮肤的温度梯度似乎与通气反应有关。体表皮肤温度平均值的变化率与通气反应之间没有显著相关性。结果表明，冷水浸泡期间通气增加的主要驱动因素是深部皮肤温度的变化率。
