随着生活水平的不断提高,乘机旅行的人越来越多。由于坐飞机时会产生突然的环境变化,机舱内的小气候与地面居室有很大不同,这对于某些旅客特别是一些患病乘客来说,可能会产生某些不适。因此,加强自我保健是十分必要的。 研究表明,对乘客影响较大的小气候因素主要包括—— 低气压 现代新型的飞机一般都有自动调压设备。大部分喷气式飞机的飞行高度距海平面9000～10000米。在这个高度上,座舱内的大气压可调节到相当于离海平面1500～2000米高度的气压。空气压力降低会导致血液中血红蛋白含氧比例降低,对于血液系统或呼吸系统有疾病的人影响较大。
With the continuous improvement of living standards, more and more people take the opportunity to travel. Due to the sudden environmental changes that occur when flying, the microclimate in the cabin is very different from that in the ground, which may cause some discomfort to some passengers, especially some sick passengers. Therefore, it is very necessary to strengthen self-care. Studies have shown that microclimate factors that have a major impact on passengers include: - Low air pressure Modern new aircraft typically have automatic pressure regulating equipment. Most jet aircraft flying height from the sea level of 9000 to 10000 meters. At this altitude, the atmospheric pressure in the cockpit can be adjusted to a pressure equivalent to a height of 1500 to 2000 meters from the sea level. A decrease in air pressure results in a reduced rate of hemoglobin oxygen in the blood and a greater impact on people with blood or respiratory illnesses.
