To determine the influence of variations in the temperature and humidity of inhaled air on the nasal mucosal temperature at various sites in the nasal airways.
Fifteen volunteers were enrolled in the study. The temperature was measured on the mucosal surface of the nasal septum at the level of the nasal vestibule, in the nasal valve area, anterior turbinate area and choanae. Temperature measurements were made using a miniaturized thermocouple. Continuous temperature readings were performed before and after 10 min of exposure to either cold, dry air, ambient air or hot, humid air.
Inhalation of cold, dry air significantly reduced the temperature of the septal mucosa at each location of measurement compared to the breathing of ambient air. Inhalation of hot, humid air significantly increased the septal mucosal temperature at all detection sites
The climatic condition of inhaled air can lead to significant changes in nasal mucosal temperature. As the nasal mucosa is important for nasal air conditioning, short-term exposure to air of extreme temperature and humidity can rapidly compromise nasal air conditioning.
确定吸入空气的温度和湿度变化对鼻气道不同部位鼻黏膜温度的影响。
15名志愿者参与本研究。在鼻前庭水平的鼻中隔黏膜表面、鼻瓣区、前鼻甲区域和鼻后孔测量温度。使用小型热电偶进行温度测量。在暴露于冷干空气、环境空气或湿热空气10分钟前后进行连续温度读数。
与呼吸环境空气相比，吸入冷干空气显著降低了每个测量部位的鼻中隔黏膜温度。吸入湿热空气显著提高了所有检测部位的鼻中隔黏膜温度。
吸入空气的气候条件可导致鼻黏膜温度发生显著变化。由于鼻黏膜对鼻腔空气调节很重要，短期暴露于极端温度和湿度的空气会迅速损害鼻腔空气调节功能。
