低温对机体的影响人体各部份的组织细胞,为了维持正常的生命活动,需要从血液中摄取氧气和营养物质,进行新陈代谢。很早以前,人们就观察到,在不同的温度下,细胞为了维持正常的功能,所需氧气的数量是不同的。譬如说,假如37℃时需要100％,而在22℃时只需要约25％,在6℃时就只需要3％了。换句话说,同样一点氧气,如果在37℃时可以维持细胞的生命活动5分钟,那末,在6℃时就可以维持160分钟。这是由于代谢随着温度的降低而减慢的缘故。
The hypothermia affects the body’s tissue cells in various parts of the body. In order to maintain normal life activities, it is necessary to take in oxygen and nutrients from the blood for metabolism. Very early on, people observed that at different temperatures, the amount of oxygen needed by cells in order to maintain normal function was different. For example, if you need 100% at 37°C and only about 25% at 22°C, then only 3% at 6°C. In other words, the same amount of oxygen, if it can maintain the cell’s vital activity for 5 minutes at 37°C, can be maintained at 6°C for 160 minutes. This is due to the fact that metabolism slows down as the temperature decreases.
