FiO2

PaO2 / FiO2 and breathing rates are sensitive parameters for early detection of ARDS .

PaO2／FIO2和呼吸频率是早期发现ARDS的临床指标；

PaO2 increased at 5-15 minutes after PS , then FiO2 and MAP decreased .

给PS后5～15分钟PaO2显著上升，随后可调低吸入氧浓度（FiO2）和平均气道压（NAP）。

Keep FiO2 ( within 60 % );

限制吸氧浓度（≤60%）；

In the survival group , PaO2 / FiO2 and PaO2 / PAO2 were increasing gradually in order in each period ;

生存组各时段的PaO2/FiO2和PaO2/PAO2顺次增大；

Group B also showed that all these lung mechanics were improved except unchanged PaO2 / FiO2 , whereas group A showed that the all above aggravated during the whole therapy .

B组在治疗过程中除PaO2／FiO2无明显变化外，其余所有呼吸力学参数均有好转；

As compared with pre-treatment , the blood gas analysis after 6 hours were significantly improved beside PaO2 and PaO2 / FiO2 ( P < 0.05 , P < 0.01 );

治疗后6h与治疗前比较除PaO2、PaO2/FiO2外，血气均明显改善（P<0.05，P<0.01）；

In Vt 25 group , the microscopic examination revealed mild lung injury , PaO2 / FiO2 decreased mildly but the lung injury standards were not met in this group .

Vt25组病理学检查有一定程度的肺损伤，PaO2／FiO2有所下降，但未达到急性肺损伤标准。

To determine the safety and gas changes of lungs during low flow nitrous oxide-oxygen anesthesia , FiO2 , gases of alveoli , inspired gases and blood gases were measured respectively .

应用动物实验与临床研究相结合的方法，观察了低流量固定比例的氧化亚氮&氧麻醉期间FiO2、吸入气、肺泡气以及动脉血气变化。

The organ bath for PA rings tension study was employed . Adult male Wistar rats were raised in hypoxic environment with fractional inspired oxygen ( FIO2 , 0.12 ) for 9 d.

制备缺氧大鼠动物模型，成年雄性Wistar大鼠在低氧环境下（吸入氧分数为0.12）正常喂养9d。

Alveolar PO2 ( PaO2 ), fraction of inspired oxygen ( FiO2 ), and mean airway pressure ( MAP ) were measured , and chest radiographs were taken , for each patient before and after treatment .

分别在治疗前后测定动脉氧分压（PaO2）、吸入氧浓度（FiO2）、平均气道压（MAP）、拍胸片。

The survival patients ' albumin , arterial oxygen pressure ( PO2 ) and oxygen index ( PO2 / FiO2 ) were higher than those of the death group , while the creatinine , urea nitrogen , blood lactate were significantly higher in the death group than the survival group .

存活组患者白蛋白、动脉血氧分压（PO2）和氧和指数（PO2/FiO2）高于死亡组，而死亡组患者的肌酐、尿素氮、动脉血乳酸均明显高于成活组。
