在使用氧气的注意事项中,有一项是不可将筒内氧气用空,应留100磅或保留5个气压的氧气。目前,我们在临床上用的氧气表,一般都是用公斤/厘米~2来表示,那么,怎样从氧气表上看出筒内尚有100磅或5个大气压的氧气呢?我们通过学习,换算出100磅/英寸~2约等于7公斤/厘米~2;5个气压等于5公斤/厘米~2;而氧气表上每一个小格等于10公斤/厘米~2。由此可知,当氧气表上只剩1个小格时,就应该停止使用。
In the use of oxygen, one of the reasons is not to empty the cylinder oxygen, should be left at 100 pounds or retain 5 atmospheres of oxygen. Currently, we are in the clinical use of oxygen meter, are generally expressed in kg / cm ~ 2, then, how to see from the oxygen meter cylinder still have 100 pounds or 5 atmospheres of oxygen it? Through our study, Conversion of 100 pounds / inch ~ 2 is equal to about 7 kg / cm ~ 2; 5 pressure is equal to 5 kg / cm ~ 2; and each small box on the oxygen meter is equal to 10 kg / cm ~ This shows that when there is only one small cell on the oxygen meter, it should stop using it.
