Objective To evaluate the effectiveness of bronchoscopic lung volume reduction using one?

目的 评价使用纤维支气管镜单向活瓣支架肺减容术治疗肺气肿动物模型的疗效和安全性。

Methods:In a less invasive bronchoscopic approach designed to mimic LVRS,one-way valves are inserted into selected bronchi in emphysematous portions of the lung.

目的：探讨支气管镜肺减容术的作用机制、适应证、安全性、疗效、景方法：与肺减容术相似，通过纤维支气管镜向肺气肿部分的支气管置入单向活瓣。

The valves create atelectasis of emphysematous lung tissue by preventing air from entering,while allowing venting of expired gas.

The example seen here is a "tension" pneumothorax shifting the mediastinum, because a "ball-valve" air leak is increasing the air in the right chest cavity.

图为张力性气胸，因呼吸时活瓣样的结构使气体漏入到胸膜腔的越来越多，纵膈移位。

Methods: Twenty ASA Ⅱ~Ⅲ patients aged 28~69 years were randomly divided into 2 groups:(1)3-mins group (n=10).(2)8 deep breathings group (8DB). Arterial blood samples were drawn with a fraction of inspired oxygen of 0.21for arterial blood gas analysis. Before induction of anesthesia, patients in 3 mills group were asked to breathe normally for 3 mins during which 100% oxygen at 10 L/min through an anesthesia mask attached to a circle system with soda lime was adopted, and adjustable pressure limiting valve was kept open.

20例气管插管患者随机分为吸氧去氮组（3MIN组）与60s深呼吸8次组（8DB组），入手术室后在呼吸空气情况下采集动脉血气标本测定血气分析，并记录SpO2值。3MIN组采用完全密闭面罩，氧流量10L，麻醉机活瓣旋开以15次／min频率自然呼吸3min.8DB组在相同条件下在60s内深呼吸8次。

Gas of analgesia of use emergency treatment supplies equipment, device includes air feed a powerful person and the veil that take automatic valve each one, with hose connection, inspiratory sex air feed undertakes below valve automata.

使用急救镇痛气体供给设备，装置包括供气阀和带自动活瓣的面罩各一，用软管连接，在活瓣自动控制下进行吸入性供气。

The liquid which expands in the heat sensor with the rise of temperature forces its way over the capillary tube in the actuator by means of removing a plunger piston, which is made tight externally be means of a flexible metallic tube, at which the pi- ston rod, which comes out of the actuator, moves the valve rod against a spring and a closing valve throttles or closes.

在热感应器中扩张的液体由于那在毛细管上的温度军队的上升它的方法在那主动器经由除去一个跳进的人活塞，这被做紧紧地外部地是有柔性的金属管方法哪里 pi-从主动器出来的 ston 竿移动活瓣竿相对于一个春天和一个结束活瓣节流阀或结束。

The air in the tire leaked out through the valve.

轮胎内的空气从活瓣漏出。

This one mode pays close attention to network credence foundation of the businessman very much.
