The major responsibility of the anesthesiologist is to provide adequate respiration for the patient. The most vital element in providing functional respiration is the airway. No anesthetic is safe unless diligent efforts are devoted to maintaining an intact functional airway.
麻醉医师在气道管理上的主要职责是确保患者充分的呼吸。气道是维持呼吸功能最主要的部分，如果没有充分保证呼吸道的通畅。任何麻醉都是不安全的。
米勒麻醉学Chapter 42 - Airway Management
The normal airway begins functionally at the nares. As air passes through the nose, the important functions of warming and humidification occur. The nose is the primary pathway for normal breathing unless obstruction by polyps or upper respiratory infection is present. During quiet breathing, the resistance to airflow through the nasal passages accounts for almost two thirds of the total airway resistance. The resistance through the nose is almost twice that associated with mouth breathing. This explains why mouth breathing is used when high flow rates are necessary as with exercise.
正常功能气道从鼻孔开始，鼻腔的重要功能是对空气的加温和湿化作用。除非患有鼻息肉或上呼吸道感染，一般情况下，呼吸经鼻开始。平静呼吸时气流通过鼻腔的阻力大约占总气道阻力的2/3，经鼻呼吸时的气道阻力大约是经口呼吸的两倍。这就是为什么人们在运动等需要高流量通气时常经口呼吸。

Gastric inflation rarely occurred when pressures less than 15 to 20 cm H2O were used. In general, such pressures were associated with tidal volumes well in excess of 1 L.
在15～20 cm H2 O 的压力下，胃胀气很少发生。达到导致胃内容物反流的压力时，潮气量往往超过1L 。
米勒麻醉学Chapter 42 - Airway Management
Oropharyngeal obstruction can also be overcome to some extent by increased oropharyngeal pressure from manual inflations with a breathing bag.
口咽腔梗阻也可以通过呼吸囊加压通气在某种程度上得以解决
米勒麻醉学Chapter 42 - Airway Management
One of the major concerns with such manual inflation of the lungs without tracheal intubation is the potential for gastric insufflation with high inflation pressures.
这种人工加压通气的方式，主要的后果是因压力增加引起胃内容物的反流误吸。
米勒麻醉学Chapter 42 - Airway Management
The relationship between pressure and gas entry into the stomach has been examined in unconscious, paralyzed patients.
压力和进入胃气体量的关系已在麻醉的患者身上得到检验。

The problem was explained to the patient & her husband. The patient was then put under general anesthesia , caesarean section was done to delivered her baby .
问题是向病人和她的丈夫解释，病人需要在全身麻醉下行剖宫产术，来为她接生。
随着血氧饱和度监测的普及应用,普鲁卡因静脉复合麻醉并发高铁血红蛋白血症的检出率明显增加
With the popularity of oxygen saturation monitoring applications, procaine intravenous anesthesia complicated by methemoglobinemia significantly increased the detection rate
The problem was explained to the patient & her husband. The patient was then put under general anest ...

这段话应译为：在向病人和她的丈夫解释所发生的问题之后，就给病人全身麻醉，以行剖宫产手术接生。
