飞机是现代化的交通工具,随着我国民航事业的不断发展,乘坐飞机的人也越来越多。但是当您发生上呼吸道感染或患有某些鼻腔疾病时,最好勿坐飞机,改乘车船。为何患上呼吸道感染及某些鼻腔疾病的人暂不宜乘坐飞机呢?这得从气压的变化对鼻窦的影响谈起。飞机的升降可引起机内气压的改变。当飞机升空时,机内气压逐渐降低,鼻窦内气压高于机外气压。当飞机降落时,机外气压增大,达到正常的大气压,又高于鼻窦内气压。人体为了保持鼻窦内压力与外界气压的平衡状态,只有通过鼻窦出口的气流来维持。但是患有上呼 Aircraft are modern means of transport. As China’s civil aviation industry continues to develop, more and more people fly by plane. But when you have upper respiratory tract infection or suffering from some nasal diseases, it is best not to fly, change travel. Why people suffering from respiratory infections and some nasal diseases temporarily should not take a plane? This change from the pressure on the sinuses to talk about. Aircraft movements can cause changes in the pressure within the machine. When the aircraft was launched, the pressure inside the machine gradually decreased, and the pressure inside the sinus was higher than the pressure outside the machine. When the plane landed, the pressure outside the machine increased to reach normal atmospheric pressure, which is higher than the pressure inside the sinus. The body in order to maintain the internal pressure of the sinus and the balance of external pressure, only through the exit of the sinus flow to maintain. But suffering from the call
