Results We analyzed homodynamic when the patients applied mechanical ventilation for respiratory failure patients of the great ages. 1） When VT was ≥10 ml/kg and PEEP was set at 0～10 cmH2O, or when VT was 6～12 ml/kg and PEEP was 〉10 cmH2O, the respiratory tract produced high peak pressure and the inspiration platform pressure, with which HR and CVP increased, and SBP, DBP, CI and CO decreased.

结果1。高龄患者在VT达≥10ml/kg时，在PEEP设定为0～10cmH2O范围内；或PEEP≥10cmH2O时，VT设定在6～12ml/kg范围内时，均可产生较高的气道峰压和吸气平台压，产生HR和CVP增高，SBP、DBP、CI和CO下降等血流动力学异常。2。

BACKGROUND: We evaluated the usefulness of the hyomental distance ratio, defined as the ratio of the HMD at the extremeof head extension to that in the neutral position, in predictingdifficult visualization of the larynx in apparently normalpatients, by examining the following preoperative airway predictors,alone and in combination: the modified Mallampati test, HMDin the neutral position, HMD and thyromental distance at theextreme of head extension and HMDR.

背景：我们通过以下单一或混合的术前气道指标评估了颏舌距离比在预测表面上正常的患者喉镜检查时发生困难视野的可靠性：改良Mallampati 试验、头部中立位时的HMD、头部最大伸展位时HMD和甲颏距离以及HMDR.HMDR定义在为头部最大伸展位和中立位时HMD的比值。

Background: Subepithelial hypervascularity and angiogenesis in the airways are part of structural remodelling of the airway wall in asthma, but the effects of inhaled corticosteroids on these have not been explored.

背景：气道上皮下血管过度形成及血管发生是哮喘患者气管壁结构重建的一部分，但是吸入型糖皮质激素在这方面的作用并没有被研究。

Methods:①Make clinical scale of the magnitude of the tongue and the palate to the group of the OSAHS and the normal control②Successive scanning of the upper airway at the states of the normal inspiration and under the Müller action on both normal controls and the OSAHS patients with multi-slice spiral computed tomography. The scope of scanning was from the roof of nasopharynx to the level of hypohyal, bonding multiplate volume reconstruction,using the image workstation to survey the cross section area, sagittal diameter, coronal diameter on the soft tissue thickness in the lateral pharyngealwall and posterior wall of the pharynx, and the postzone of soft palate, uvula palatine ,tongue and epiglottis.

采用高分辨率多排CT(multi-slice spiral computed tomography，MSCT)对正常人和OSAHS患者的上呼吸道分别在平静吸气状态下以及Müller动作下进行连续扫描，扫描范围从鼻咽顶部至舌骨下缘，图象进行三维重建，应用图像工作站测量正常人和OSAHS患者的软腭后区(retropalatal region，RP)、悬雍垂后区(uvula region，UV)、舌后区(retroglossal region，RG)和会厌后区(epiglottal region，EPG)气道横截面积(cross section area，CSA)、矢状径、冠状径、咽侧壁和咽后壁软组织厚度以及舌体大小(包括舌体长度、舌体最宽处的宽度、中纵切面面积，舌背高度)。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
