鼻腔粘膜依赖丰富的血管神经和腺体的分泌,对吸入的空气有效地进行热量和湿度的调节。此外,还赖于鼻气道有适当的阻力,以有助于调节吸入气体的湿热、下呼吸道的功能、正常呼吸时肺泡的气体交换,以及体内诸因素的平衡关系。因此,研究人的鼻气道阻力,有重要的生理学和病理学意义。 Nasal mucosa is dependent on the secretion of abundant vascular nerves and glands for effective regulation of heat and humidity on inhaled air. In addition, the nasal airway also depends on the proper resistance to help regulate the damp heat of inhaled gases, the function of the lower respiratory tract, the alveolar gas exchange during normal breathing, and the balance of various factors in the body. Therefore, the study of human nasal airway resistance, there are important physiological and pathological significance.
