正常人能够在极端寒冷的环境中活动，而不会出现呼吸困难的症状或呼吸道受损。1这种保护能力可能是因为在极端气候条件下，正常的呼吸道对吸入的空气进行加热和增湿的能力非常有效。2研究表明，在-100℃时从嘴唇输送的空气在到达气管分叉时被加热到体温的1到2°以内。3另一方面，患有慢性呼吸系统疾病的患者，如肺气肿、支气管哮喘或慢性支气管炎，可能会。
NORMAL man is able to function in an extremely cold environment without experiencing symptoms of respiratory difficulty or suffering injury to his airways.1 This protective ability may be due to the fact that the normal respiratory tract is highly effective in its ability to heat and humidify inspired air under extreme climatic conditions.2 Studies have shown that air delivered at the lips at -100°C. is heated to within 1 or 2° of body temperature by the time it reaches the tracheal bifurcation.3 On the other hand, patients with chronic respiratory disease, such as emphysema, bronchial asthma or chronic bronchitis, may . . .
