气管

One two-steps variable resonance pipe-length of induction system has been excogitated and the control strategy was put forward. Using this system, the max.

用长进气管则谐振转速低，可提高低速范围的充气效率，从而提高最大转矩；用短进气管则谐振转速高，可提高高速范围内的充气效率，从而提高最大功率。

The most common artificial airway is intubated, and tracheotomy.

最常见的人工气道是气管插管和气管切开。

Experience of cardiopulmonary resuscitation include instant intubating the arrest victims and ventilating with 100% oxygen , initiating closed-chest compression and high-dose epinephrine infusion.

复苏成功的经验是对无气管插管的心跳骤停病人立即施行气管插管，坚持胸外按压和机械通气，大剂量肾上腺素的应用。

Were subjected to tracheotomy during radix linguae and/or corpus linguae partial resection, 2 were subjected to tracheotomy before general anesthesia and UPPP surgery because of obesity and short neck, 3 were subjected to tracheotomy because of difficult tracheal intubation before general anesthesia, 3 because of 3-platform operations, and 3 because of respiratory tract obstruction after tracheal extubation postoperatively in the ICU.

行气管切开术原因分别为同时行舌根舌体手术8例；肥胖、颈短2例；气管插管困难3例；三平面手术3例；在ICU监护结束拔管后发生呼吸道梗阻3例。

Thermosoftened,obturated ETTs were more effective than simple thermosoftenedETTs in reducing epistaxis.

热软化后的装有食道听诊器的气管内导管比单纯热软化的气管内导管在减少鼻衄方面更有效。

Methods First, 704 patients receiving CO2 laryngeal laser operation from July 2, 2003 to August 21, 2008 were enrolled, and their risk events and causes were systematically analyzed. Second, in vitro experiment, we tested the tolerance of the PVC tube against different CO2 laser energy in different cutting patterns when the cuff was inflated in water or air. We also tested the combustion conditions of the PVC tube in different oxygen concentration, laser energy and cutting patterns. Results Tracheal cuff were punctured by the laser in 92 of all 704 cases. Spark and dense smoke were observed in 8 and 37 cases respectively.

一是统计和分析我院2003年7月2日至2008年8月21日进行的704例喉二氧化碳激光手术所发生的危险情况；二是通过体外试验，观察注水和注空气时气管导管套囊在不同激光能量和不同激光切割方式下对二氧化碳激光的耐受情况，以及PVC气管导管在不同氧浓度、不同激光能量和不同激光切割方式下的燃烧情况。

Corticosteroids, immunosuppressive agents and dapsone were used in these patients. Tracheotomy was performed in 4 patients with airway obstruction. Montgomery T-tube or self-expanding metal stent were used in 2 patients with tracheal collapse. Of 13 case, 2 died from respiratory complications.

治疗：用皮质激素、免疫抑制剂和氨苯砜控制症状，4例因呼吸道梗阻行气管切开术，2例气管塌陷的患者用T型管或金属支架治疗。13例中2例治疗无效，死于呼吸道并发症，5年生存率78.6%。

Massive clinical practices proof,when breathes to the palpitation stops and its the serious oxygen deficit breath failure patient,the single track dependence nose drive pipe attracts the oxygen,the face guard attracts the oxygen or the mouth suitable breath is impossible to correct the oxygen deficit condition,must promptly carry on in the trachea to insert a tube,after the mouth or the nose trachea establishment artificial respiration channel,is the effective method.

大量的临床实践证明，对于心跳呼吸停止及其严重缺氧的呼吸衰竭患者，单纯依靠鼻导管吸氧，面罩吸氧或口对口呼吸不可能纠正缺氧状态，必须及时进行气管内插管，经口或鼻气管建立人工呼吸通道，才是行之有效的方法。

A swimmer with a snorkel can still breathe, but notice that snorkelers float right on the top.

使用通气管的游泳者还能呼吸，但是会注意到通气管得恰好漂浮在顶部才行。

A swimmer with a snorkel can still breathe, but notice that snorkelers float right on the top.

带着通气管的游泳者仍然可能呼吸，但是要注意到戴上通气管的人就浮在水面上。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
